JamieFoxxGetsIntoCharacterWithHelpFromHisDentist

If you were a well-known actor, how far would you go to get inside the character you’re playing in a movie? Plenty of stars have gained or lost weight to fit the role; some have tried to relate to their character by giving up creature comforts, going through boot camp, even trying out another occupation for a time. But when Jamie Foxx played a homeless musician in the 2009 film The Soloist, he went even further: He had part of his front tooth chipped out!

“My teeth are just so big and white — a homeless person would never have them,” he told an interviewer. “I just wanted to come up with something to make the part unique. I had one [tooth] chipped out with a chisel.”

Now, even if you’re trying to be a successful actor, we’re not suggesting you have your teeth chipped intentionally. However, if you have a tooth that has been chipped accidentally, we want you to know that we can repair it beautifully. One way to do that is with cosmetic bonding.

Bonding uses tooth-colored materials called “composite resins” (because they contain a mixture of plastic and glass) to replace missing tooth structure. The composite actually bonds, or becomes one, with the rest of the tooth.

Composite resins come in a variety of lifelike tooth shades, making it virtually impossible to distinguish the bonded tooth from its neighbors. Though bonding will not last as long as a dental veneer, it also does not require the involvement of a dental laboratory and, most often, can be done with minor reshaping of the tooth.

Cosmetic Bonding for Chipped Teeth
A chipped tooth can usually be bonded in a single visit to the dental office. First, the surface of the tooth may be beveled slightly with a drill, and then it is cleaned. Next, it is “etched” with an acidic gel that opens up tiny pores. After the etching gel is rinsed off, the liquid composite resin in a well-matched shade is painted on in a thin layer, filling these tiny pores to create a strong bond. A special curing light is used to harden this bonding material. Once the first layer is cured, another layer is painted on and cured. Layers can continue to be built up until the restoration has the necessary thickness. The bonding material is then shaped and polished. The whole procedure takes only about 30 minutes!

SolvingtheProblemofMissingTeethWithOrthodonticsandRestorations

Normally, teeth erupt and grow in a symmetrical alignment: on the top palate, for example, the two central incisors take center stage; on either side are the lateral incisors, and then beside these the canines (cuspids).

But what happens when teeth don’t grow in? The result can be a smile that just doesn’t quite look right; more importantly, normal function is impaired because the person can’t grasp and chew food correctly.

These missing teeth are the result of a congenital (“from birth”) defect. It’s estimated that almost a quarter of all people are missing one or more wisdom teeth, and more than 5% are missing one or more second premolars or upper lateral incisors.

In a normal arch (the upper or lower set of teeth), each tooth type performs a particular role during eating. A missing tooth causes the remaining teeth to compensate, but beyond their capacity. The remaining teeth also tend to move to fill in any gaps left by the missing teeth, as when the eye teeth move toward the central incisors in the absence of the lateral incisors. This puts them out of position, so they can’t cover (“occlude”) their counterparts on the other arch and grasp food properly.

To improve the smile and restore proper chewing function it’s necessary to first move these “out of position” teeth to their correct position through orthodontics. We would then fill the gaps that result with life-like restorations (preferably dental implants with crowns) that resemble the type of tooth that should be there.

The restoration needs to be timed carefully, especially for young patients whose jaw structure has not fully developed. If implants are installed before the jaw’s full maturity (usually late teens or early twenties), the implant crowns may not appear to be the right length as the jawbone continues to grow. Since bone growth depends on the normal pressures exerted by the teeth, there may also be insufficient bone mass in the gap area to support a dental implant. Growing bone with bone-grafting material may be necessary before installing implants.

The total process could take many months or even years, depending on age and other conditions. In the end, though, the results can be astounding — better function and a vibrant, new smile.
