The Tooth Book

Teeth–they come in handy when you chew or smile! In Dr. Seuss’s hilarious ode to teeth, little ones will laugh out loud as they find out all the things teeth can do and how to take care of them so they last a lifetime!  

Just Going to The Dentist

Mercer Mayer's very popular Little Critter is on his way to the dentist. It's a thorough check-up, complete with dental x-rays. When Dr. Ghum insists on filling a cavity, Little Critter goes through it bravely. The visit is painless to the reader because of Little Critter's funny, honest way of look at things -- including the world of dentistry.

Braces

Dental braces: Which type makes the right choice for you?

Say goodbye to the "tin grin," you have lots of other options.

When it comes to having your teeth straightened, you'll find that you have lots of treatment alternatives to choose from.
Here's a list of the types of braces, or options, that your dentist should be able to offer:
  • Invisible (Invisalign®)
  • Lingual (iBraces®)
  • Ceramic (Clear)
  • Metal (Including gold braces, fashion brackets, personalized color schemes)

I) Regular braces - You can dress them up or blend them in.

Having traditional braces (brackets and wires on the front side of your teeth) doesn't mean you have to put up with having an old-fashioned "tin grin."
Nowadays there are lots of cosmetically-pleasing variations you can opt for.

A) Ceramic / Clear Braces.

This alternative to regular metal braces involves the use of tooth-colored, or clear, ceramic orthodontic brackets.
The obvious advantage of this choice is that your brackets will more closely match the color of your teeth, and therefore help your braces to blend in better with your smile.
Ceramic braces still require the use of a metal archwire that runs across your teeth and fits into each bracket. It may, however, be possible for your dentist to use a "frosted" one.  

B) Gold Braces

Orthodontic hardware can be treated so it looks like it has been made out of gold. Some patients feel that gold braces have a softer, warmer appearance than stainless steel. Others like its luster and think it creates a distinctive look for their smile, somewhat reminiscent of fine-quality jewelry. 
Colored elastic bands worn with braces.

C) Colored Orthodontic Bands

Regular braces can be spiffed up and customized so they are colorful and exciting.
You do this (and it doesn't cost you anything) just by picking out your own special color scheme when you select the elastic bands that are used with your braces.
 

D) Designer Orthodontic Brackets

You can opt for orthodontic brackets that have a unique or fun design, such as hearts, diamonds, flowers or footballs.  

E) "Mini" Orthodontic Brackets

Your orthodontist may be able to use miniaturized orthodontic brackets with your case. Because they are smaller, they can help to make your braces less noticeable.
As an added benefit, a smaller bracket means that a person's braces won't stick out quite as far off the surface of their teeth. This can make having braces more comfortable since they won't rub against your lips and cheeks quite so much.

II) Alternatives to having regular braces.

The following are treatment-approach alternatives to having traditional braces.

A) Invisible braces (Invisalign®)

A comparison of the appearance of Invisalign ® vs. traditional braces.
"Invisible" braces are a relatively new treatment alternative that involves the use of plastic aligners to realign the patient's teeth (instead of wires and brackets like with regular braces).
And just as their name implies, since the aligners are made out of a thin, clear plastic, it's hard for other people to tell that they're being worn.
As an added benefit, you remove the aligners when you eat or clean your teeth, which makes having braces less of an ordeal. The dominant brand name associated with invisible braces is Invisalign®. 

B) Lingual Braces (iBraces®)

Lingual dental braces.
This alternative can be thought of as regular braces that have been mounted on the backside of a patient's teeth.
As opposed to invisible braces, lingual braces are sometimes referred to as being "non-visible." That's because if someone looks really closely at your mouth, they'll probably see a hint of them. But otherwise, most people won't notice them at all.
One brand name associated with this treatment option is iBraces®.  

Wisdom Teeth FAQ

Wisdom Teeth

Link to types of impactions animation.
Link to 3rd molar x-rays slideshow.

1) What are they?

"Wisdom teeth" are a type of molar. Molars are the large chewing teeth found furthest in the back of the mouth.
Most people have 1st, 2nd and 3rd molars. A person's third molars are their wisdom teeth.

a) When do they come in?

For most people, the eruption process takes place during their late teens or early twenties (usually ages 18 to 24 years), although eruption outside of this age range is not uncommon. If there is not enough room for the teeth, or they are not aligned properly, they may never fully erupt. (See "Impacted Teeth" below.)
An x-ray showing a person's upper and lower teeth on their right side.
Details about which teeth are a person' wisdom teeth.

b) How many wisdom teeth does a person have?

People usually have four: upper left, upper right, lower left, and lower right.
If they don't, it's due to their genetic makeup. It's been estimated that about 25% of people are lacking one or more. (Faculty, 1997)

An x-ray showing different classifications of tooth impactions.
Examples of different classifications of impacted teeth.

2) What are "impacted" wisdom teeth?

In dental terminology, an "impacted" tooth refers to one that has failed to fully emerge into its expected position. (Our slideshow and the animations below provide examples.)
This failure to erupt properly might occur because there is not enough room in the person's jaw to accommodate the tooth, the tooth's eruption path is obstructed by other teeth or because the angulation of the tooth is improper.

3) Types of impactions (classifications).

Dentists use a number of terms, in combination, to describe the positioning of impacted teeth. They are mesial, distal, horizontal, vertical, soft-tissue and bony.

a) Mesial, vertical, horizontal and distal.

These terms are used to refer to the general angulation (positioning) of the tooth.
Graphic showing mesial, distal, vertical and horizontal impaction types.
Mesial, distal, vertical and horizontal tooth impactions.
  • The term "Mesial" (also mesio-angular) means that the tooth is angled forward, toward the front of the mouth. This is the most common type of wisdom tooth impaction.
The other types of impactions, in order of frequency of occurrence, are the vertical, horizontal, and distal types.
  • Vertical impactions have a relatively normal orientation.
  • Horizontal (also traverse) impactions have an alignment where the tooth is lying on its side.
  • Distal (also disto-angular) impaction has an angulation that is generally directed towards the rear of the mouth.Show
Graphic illustrating soft tissue and bony impaction types.
Full-bony, partial-bony and soft-tissue impactions.

b) Soft-tissue and bony wisdom tooth impactions.

In combination with the classifications above, wisdom teeth are also categorized as soft tissue or bony impactions.
  • A "soft tissue" impaction is one where the upper portion of a wisdom tooth (the tooth's crown) has penetrated through the bone but has not yet fully erupted through the gum tissue.
  • The term "bony" or "hard tissue" impaction indicates that the tooth still lies primarily within the jawbone. A full-bonyimpaction is entirely encased by bone tissue, whereas apartial-bony one has erupted through it somewhat.

c) How likely is it that your wisdom teeth will be impacted?

Studies suggest that the incidence of having at least one that's impacted runs on the order of 65 to 72%. (Faculty, 1997)

Graphic illustrating how a lack of jawbone space can lead to problems.
Inadequate jawbone space leads to impaction.

4) What causes wisdom tooth impaction?

The reason why some wisdom teeth are impacted is not an easy question to answer. A primary cause simply seems to be a condition of inadequate jawbone space behind a person's second molar.
Why this lack of space exists is not fully understood. There does, however, seem to be a correlation between large tooth size and/or the presence of generalized tooth crowding and having impacted wisdom teeth.

The human diet has changed.

The dietary changes adopted by modern man have been theorized as playing a role in the incidence of 3rd molar impaction.
The coarse nature of stone-age man's diet had the effect of producing extensive tooth wear (not just on the chewing surface of the teeth but also in between, where neighboring teeth touch against each other).
When this type of wear takes place, it tends to reduce the "length" of the teeth (as a set), thus creating additional jawbone space to accommodate the wisdom teeth by the time they erupt. In comparison, the diet of modern man does not usually cause a significant amount of this type of wear.
It has also been argued that the coarse nature of stone-age man's diet, as compared to modern man's relatively soft diet, probably required more chewing muscle activity. This activity could have stimulated greater jawbone growth, thus providing more space for wisdom teeth.
Additionally, the harsh world of the caveman no doubt often lead to the occurrence of broken teeth and tooth loss. Once a tooth (or a portion of it) is missing the teeth behind it have a tendency to shift forward. This type of movement would make more jawbone space available for wisdom teeth. In comparison, with the advent of modern dentistry there are relatively few reasons why a tooth should remain unrepaired or be lost.

Buckeye Star Ad for Nov 2014


Ginger Bite-Us from AAPD

She may be cute, but she has quite the bad temper. She’ll kick, bite and scratch until your gums are red and inflamed. Watch out for this horrible little hothead!


Tooth DK from AAPD

He’s the most fearsome of them all, causing cavities and toothaches everywhere he goes. He’s hatching an evil plan for mouth domination, one tooth at a time!


Tartar the Terrible from AAPD

This monster packs a mean punch. That’s because he’s working on hardening tooth buildup, which becomes far more difficult to remove than plaque.


Banning the Binky

Tips on weaning your child from the pacifier, including different approaches that can reduce stress for both kids and parents when trying to “ban the binky!”
By AAPD President Dr. Ed Moody
Many parents are thankful for the invention of pacifiers that can help calm and soothe fussy babies. Infants often use a pacifier or suck on a thumb for comfort, security or simply as a method to make contact with the world. In fact, some babies begin to suck on their fingers or thumbs even before they are born! The American Academy of Pediatric Dentistry (AAPD) recommends a pacifier over a thumb to comfort new babies since a pacifier habit is easier to break at an earlier age.
Why does this matter?AAPD_PacifierWeaning_10.24
The sucking reflex is completely normal and many children will stop sucking on thumbs, pacifiers or other objects on their own between 2 and 4 years of age.  Frequent pacifier use over a longer period of time can affect the way a child’s teeth bite together and the growth of the jaw. The upper teeth may tip outward or become crooked and other changes in tooth position or jaw alignment could occur. Intervention may be recommended for children beyond 3 years of age. The earlier a child can stop a sucking habit, the less chance there is that it will lead to orthodontic problems down the road.
My child won’t give up their pacifier – what do I do?
Some parents swear by cold turkey, while others have gradually weaned their children off pacifiers. Below are some techniques that will help your infant give up the Binky for good. But no matter which route you take, remember that as the experts in little teeth, pediatric dentists will be an invaluable resource for guidance and recommendations on the best approach to quit the pacifier.
Ask your pediatric dentist
A pediatric dentist can assist in encouraging children to stop a sucking habit and discuss each child’s particular situation. This, along with support from parents and caregivers, helps many children quit their pacifier and thumb-sucking habits. If your child needs further encouragement, pediatric dentists can also recommend behavior modification techniques to persuade children to quit the pacifier for good.
Offer an alternative
What causes your child to cry out for their beloved Binky? Once you’ve identified which situations trigger your child’s desire for a pacifier, be ready to replace it with comfort and reassurance. It can be helpful to swap out the pacifier with a transitional object such as a cuddly doll or stuffed toy. Additionally, distracting your child with a fun activity can help take their mind off the desired Binky. Be sure to offer positive reinforcement and praise when your child sleeps through the night or self-soothes without his pacifier.
Time to get creative
If you’re still running into roadblocks, it’s time to put a creative spin on the “bye-bye Binky” process. One idea is to take your child and pacifier to the store to pick out a new toy to replace their pacifier. There are many experienced store clerks who are used to this trick and are willing to play along when your child “trades in” the pacifier for a new toy of her choosing. Other parents have thrown a “Goodbye Binky” party, set out the pacifier for the Binky Fairy or donated the Binky to children who need it.
Use a countdown
If your child is resisting the idea of losing his or her pacifier, try making the process into a game. Similar to the graphic shown on this page, create a countdown game where you tell the child that over the next three to four weeks Binky will be shrinking. The first week, cut a very small hole in the top of the pacifier. Be careful to make clean cuts that do not leave any part of the pacifier hanging which could break off in your child’s mouth. Continue to cut a portion of Binky off each week until there is no longer anything left for your child to suck on. This is a great way to separate your child’s association from someone taking the pacifier away to the pacifier just breaking on its own. At the end, you can tell your child it’s time to bid Binky bye-bye.
Timing is key
Whether you decide to gradually wean or go cold turkey, make sure to time it right. Try not to take away the pacifier during life changes, major transitions or traveling so as not to put further stress on the process. Once you’ve made the plan to ditch the pacifier, make sure all caregivers are on board and stick with it! If you choose to gradually remove the pacifier, try limiting use to nap time and bed time at first. Or, let your child use the pacifier for short periods of time if you feel he particularly needs it, and gradually shorten the frequency and length of time the pacifier is used.
If you decide to go cold turkey, be sure to collect all pacifiers around the house – the last thing you need is your little one finding a pacifier the week after she gave it up and going back to square one! If you need additional ideas on how to wean your child off the pacifier be sure to ask your pediatric dentist or visit mychildrensteeth.org for further tips and a pediatric dentist locator to find a pediatric dentist near you.

AHCCCS

The Arizona Health Care Cost Containment System (AHCCCS) is the name of the Medicaid program in the state of Arizona. As with all Medicaid programs, it is a joint program between the state and the Centers for Medicare and Medicaid Services (CMS). It became the final such state Medicaid program to implemented under Title XIX (as all other states had previously created their own programs) when it began in October 1982 as a section 1115 demonstration project. The program acronym AHCCCS is frequently pronounced like the word "access."

In 1987, under a policy recommended by the AHCCCS, the Arizona state legislature voted to extend health care to some pregnant women and children in the indigent population and defund organ transplants. Subsequently, the AHCCCS received significant media attention after a woman from Yuma was denied funding for a liver transplant and died as a result.

Until 1988, AHCCCS covered only acute care, except for limited post-hospital skilled nursing facility coverage. The Arizona Long Term Care System (ALTCS) was created to allow Arizona to implement a long-term care (LTC) program for the elderly, physically disabled, and the developmentally disabled. It is administered as a distinct program from the acute care program. Registering for the ALTCS program can be done either through ALTCS directly or through a third party agency.

In 1990, AHCCCS began phasing in mental health services, beginning with coverage of seriously emotionally disabled children under the age of 18 who require residential care. Over the next five years, behavioral health coverage was extended to all Medicaid eligible persons.

In 2001, AHCCCS received permission from CMS to expand eligibility for its Medicaid acute care program to 100 percent of the Federal Poverty Level.

As of 2005, almost 1,013,800 people were served in the acute care program and close to 41,655 were enrolled in the LTC program. In addition, 50,672 children were enrolled in the Arizona SCHIP program, known as KidsCare.

How to take Dental X-Rays

A Brief History of Orthodontics by Archwired.com

If you think the desire for straight teeth is a trapping of modern society, think again! Extreme Makeovers may be new, but "braces" date as far back as ancient man!
Early History
Even ancient people wanted straight teeth! According to the AAO (American Association of Orthodontists), archaeologists have discovered mummified ancients with crude metal bands wrapped around individual teeth. To close gaps, it has been surmised that catgut did the worknow done by today's orthodontic wire! Later, in 400-500 BC, Hippocrates and Aristotle both ruminated about ways to straighten teeth and fix various dental conditions. Straight teeth have been on our minds a very long time!
While Greece was in its Golden Age, the Etruscans (the precursors of the Romans) were burying their dead with appliances that were used to maintain space and prevent collapse of the dentition during life. Then in a Roman tomb in Egypt, a researcher found a number of teeth bound with a gold wire -- the first documented ligature wire! At the time of Christ, Aurelius Cornelius Celsus first recorded the treatment of teeth by finger pressure. Despite all this evidence and experimentation, no significant events in orthodontics really occurred until the much later, in around the 1700s (although dentistry as a whole made great advancements in the interim). It should be noted that in Medieval times, specialized barbers often performed dental "operations", extractions, and procedures such as blood-letting. Let's be glad we live in the 21st Century!
Important Breakthroughs
Even before George Washington wore his famous wooden teeth, dentists were thinking about ways to correct bad bites. In 1728, French Dentist Pierre Fauchard published a book called the "The Surgeon Dentist" with an entire chapter on ways to straighten teeth. Fauchard used a device called a "Bandeau," a horseshoe-shaped piece of precious metal which helped expand the arch. French Dentist Ettienne Bourdet followed Fauchard in 1757 with his book "The Dentist's Art", also devoting a chapter to tooth alignment and appliances. Bourdet was the dentist to the King of France. He further perfected the Bandeau, and is also the first dentist (on record) who recommended extraction of premolars to alleviate crowding. He was also the first to scientifically prove jaw growth. Here's a link to a series of pages with some fascinating illustrations of early expansion devices.
Scottish surgeon John Hunter wrote (among other surgical books) "The Natural History of the Human Teeth" in 1771, clearly describing dental anatomy. Hunter coined the terms bicuspidscuspidsincisorsand molars.  His second book, "A Practical Treatise on the Diseases of Teeth", described dental pathology.  Although teeth straightening and extraction to improve alignment of remaining teeth has been practiced since early times, orthodontics as a science of its own did not really exist until the mid-1800s. 
In 1819 Delabarre introduced the wire crib, which marked the birth of contemporary orthodontics. The term orthodontia was coined by Joachim Lafoulon  in 1841. Gum elastics were first employed by Maynard in 1843. Tucker was the first to cut rubber bands from rubber tubing in 1850. And in the late 1800s, Eugene Solomon Talbot was the first person to use X-rays for orthodontic diagnosis. But all this was nothing compared to advances in orthodontics in the 20th Century.
Daddy-O (as in Orthodontic)
Historians claim that several men deserve the title of being called "The Father of Orthodontics." Fauchard certainly took orthodontics out of the dark ages, but these men really put maloclussion on the map. One man was Norman W. Kingsley, a dentist, writer, artist, and sculptor.  In 1858, he wrote the first article on orthodontics, and in 1880, his book "Treatise on Oral Deformities" was published. The second man who deserves credit was a dentist named J. N. Farrar who wrote two volumes entitled "A Treatise on the Irregularities of the Teeth and Their Corrections". Farrar was very good at designing brace appliances, and he was the first to suggest the use of mild force at timed intervals to move teeth. 
In America in the early 1900s, Edward H. Angle devised the first simple classification system for malocclusions, which is still used today (Class I, Class II, and so on). His classification system was a way for dentists to describe how crooked teeth are, what way teeth are pointing, and how teeth fit together. Angle contributed significantly to the design of orthodontic appliances, incorporating many simplifications. He founded the first school and college of orthodontics, organized the American Society of Orthodontia in 1901 (which became the AAO in the 1930s), and founded the first orthodontic journal in 1907. A journal and website bearing his name still thrive today. His highly praised reference book, "Malocclusion of the Teeth" went through seven editions. In the wake of all these advancements, the field of orthodontics and dentofacial orthopedics eventually became a respected dental specialty in its own right.
Other innovations in orthodontics in the late 1800s and early 1900s included the first textbook on orthodontics for students, published by J.J. Guilford in 1889, and the use of rubber elastics, pioneered by Calvin S. Case (some believe it was H. A. Baker).
The First Metal Mouths
What did braces look like a century ago? In the early 1900s, orthodontists used gold, platinum, silver, steel, gum rubber, vulcanite (and occasionally, wood, ivory, zinc, copper, and brass) to  form loops, hooks, spurs, and ligatures. Fourteen- to 18-karat gold was routinely used for wires, bands, clasps, ligatures, and spurs, as were iridium-platinum bands and arch wires, and platinized gold for brackets. Why gold? It is malleable and easy to shape. Gold had its drawbacks, however -- because of its softness it required frequent adjustments, and it was expensive! Anyway, you guessed it -- these bands wrapped entirely around the each tooth -- the original "metal mouth" was real gold or silver! How's that for bling?
In 1929, the first dental specialty board, the American Board of Orthodontics, was born. On a side note, the first synthetic (nylon)-bristle toothbrush was invented in 1938. Around this time, stainless steel became widely available, but using it for braces was considered somewhat controversial. It wasn't generally accepted as a material for orthodontic treatment until the late 1950s/early 1960s! In addition, you may be surprised to learn that x-rays were not routinely used in orthodontic treatment until the 1950s!
Advancements in the 1970s
Braces continued to wrap around the teeth until the mid 1970s, when direct bonding became a reality. Why did it take so long for dentists to invent the modern bonded bracket? The adhesive! The bonded bracket was actually invented earlier, but the formulation for the adhesive wasn't perfected until almost a decade later. At first, bonded brackets were (of course) made of metal. Like any new method, it took a while for the direct bond bracket to catch on -- which is why some people may remember wearing the old "wrap around" metal braces into the late 1970s.
Around this time, the self-ligating bracket also appeared on the scene. Self-ligating brackets don't need tie wires or elastic ligatures to hold the arch wire onto the bracket -- they are held on by a "trap door" built into each bracket. As early as 1935, the idea of a self-ligating brackets began to take shape. Over the years many designs were patented, but few were commercially available until Ormco created the Edgelock system in 1972. As the 1980s and 1990s progressed, many companies created their own versions of self-ligating brackets and improved upon the idea by offering both passive and active resistance on the arch wire. Nowadays, we have a number of self-ligating choices, such as Orec's Speed Braces, Ormco's Damon System, GAC's In-Ovation, and Adenta's Evolution.
In the 1970s, Earl Bergersen, DDS created the passive Ortho-Tain appliances, which guide jaw growth and help correct orthodontic problems and malocclusions in both children and adults. The Ortho-Tain appliances look like custom plastic mouthguards, and are worn mainly at night, or for only a few hours each day. In many cases, people have been able to correct (or greatly  diminish) many types of orthodontic problems with these removable custom-made appliances.
Around 1975, two orthodontists working independently inJapan and the United States started developing their own systems to place braces on the inside surfaces of the teeth -- lingual braces. These "invisible braces" offered people the results of bonded brackets with one big advantage -- they were on the inside of the teeth, so nobody else could see them!  In America,  the late Dr. Craven Kurz of Beverly Hills California developed the Kurz/Ormco lingual system. In Japan, Professor Kinya Fujita, of Kanagawa Dental University invented his own lingual system, and continues to make great advances in the lingual method. 
It takes special training to treat a patient with lingual braces, and many American orthodontists in the 1970s and 1980s were reluctant to use the method -- but orthodontists in other countries readily embraced it, and continued to make advancements with new techniques. Recently, lingual braces have become more popular because technology has made them more comfortable. One example is iBraces, a company which custom-fabricates brackets for a patient's teeth with the aid of digital computer imaging.
Lingual braces were the "invisible" braces of choice until the early 1980s, when "tooth colored" esthetic brackets made from single-crystal sapphire and ceramics came into vogue. Nowadays we also have brackets made from a combination of ceramic and metal -- giving the patient a strength of metal with esthetic look of less noticeable "tooth colored" braces. Recently, a European company even invented a ceramic bracket that is self-ligating!
Invisible Braces via Silicon Valley
As far back as 1945, orthodontists realized that a sequence of removable plastic appliances could move teeth toward a predetermined result. Some orthodontists even made simple plastic "aligner trays" in their offices for minor adjustments. But it took an adult who'd just had braces to take the concept a step further.
Invisalign was the brainchild of Zia Chishti and Kelsey Wirth, graduate students in Stanford University's MBA program. Wirth had traditional braces in high school (she reportedly hated them). Chishti had finished adult treatment with traditional braces and now wore a clear plastic retainer. He noticed that if he didn't wear his retainer for a few days, his teeth shifted slightly -- but the plastic retainer soon moved his teeth back the desired position. In 1997, he and Wirth applied 3-D computer imaging graphics to the field of orthodontics and created Align Technologies and the Invisalign method. With a boost from ample Silicon Valley venture funding, Align soon took the orthodontic industry by storm. Dentists and other dental companies were skeptical at first, because neither Chishti nor Wirth had any professional dental training. Invisalign braces were first made available to the public in May, 2000 and proved extremely popular with patients. Soon similar products began appearing on the market, made by GAC,
3-M Unitek, Ormco, OrthoClear, and others.
The Future: Technology Continues to Advance
As technology enhances our daily lives, it also continues to advance the science of orthodontics. More and more companies are utilizing digital computer imaging to make orthodontic treatment more precise. The SureSmile system by OraMetrix, for example, takes a detailed 3-D model of a patient’s teeth and helps the orthodontist develop a precise treatment plan for tooth movement. The orthodontist's treatment plan then drives a highly accurate robotic process to customize the arch wires needed for treatment. This often shortens treatment time and gives highly accurate results.
NASA developed one of the late 20th century's most dramatic orthodontic breakthroughs: heat-activated nickel-titanium alloy wires. At room temperature, heat-activated nickel-titanium arch wires are very flexible. As they warm to body temperature they become active and gradually move the teeth in the anticipated direction. Because of their high-tech properties, these wires retain their tooth-moving abilities longer than ordinary metal wires and need less frequent attention from the orthodontist. Many orthodontists now employ heat-activated wires in their treatment plans.
What does all this mean for the orthodontic patient of the future? As companies develop more precise, high-tech materials and methods, your braces will be on for a shorter period of time, be smaller and less visible, result in less discomfort, and give great results. We've sure come a long way from the wrap-around "metal mouth" -- and that's something we can all smile about!

No, the statue didn't really have braces. I Photoshopped them in. As if you couldn't tell.

Trauma Guidelines

Concussion -
No treatment is needed only observation.
Soft food for 1 week
Clinical control at 1 week, 6-8 weeks

Subluxation -
No treatment is needed. Observation
Soft food for 1 week
Clinical control at 1 week, 6-8 weeks

Extrusion -
For minor extrusion (< 3mm) in an immature developing tooth, either careful reposition the tooth or leave the tooth for spontaneous alignment.
Extraction is the treatment of choice for severe extrusion in a fully formed primary tooth.
Soft food for 1 week.
Clinical control after 1 week. Clinical and radiographic control at 6-8 weeks, 6 months, and 1 year.

Lateral luxation -
If there is no occlusal interference, as is often the case in anterior open bites, the tooth should be allowed to reposition spontaneously.
When there is occlusal interference local anesthesia should be applied where after the tooth should be repositioned by gentle combined labial and palatal pressure.
For teeth with severe displacement in a labial direction, extraction is the treatment of choice. Extraction is indicated in these cases because of the collision between the primary tooth and the permanent tooth germ.
Soft food for 10-14 days.
Clinical control after 1 and 2-3 weeks. Clinical and radiographic control at 6-8 weeks and 1 year.
