Children's permanent teeth normally erupt over several years after first forming below the gum line. All their permanent teeth should come in by the time they reach early adolescence.
Unfortunately, this process doesn't always happen as it should. If the erupting teeth become crowded due to a poor bite (malocclusion), teeth still to come in may not have enough room to fully erupt. They become impacted, a condition in which the visible crown remains partially or completely submerged below the gum line.
Impacted teeth create consequences for other teeth and dental health overall. They more readily cause abscesses (a localized infection within the gum tissue) and can damage the roots of nearby teeth. Impacted front canine (eye) teeth can interfere with bite function and their visual absence mars an otherwise attractive smile.
If your child's canine teeth have failed to erupt properly, there is a way to help them fully come in if you act before their mouth structure fully matures. The first step is an orthodontic evaluation of their entire bite. This will determine if there's enough space to move other teeth to make room for the impacted canines.
If so, we would then find the exact position of the impacted teeth using x-rays and possibly cone beam CT scanning for a detailed three-dimensional image. The teeth could be in a variety of positions, such as angled toward the roof of the mouth or cheek or buried high in the jawbone. If the teeth are too far out of position the best course of action may be to remove them and replace them later with a dental implant.
If the impacted teeth, though, are in a feasible position for retrieval, we first expose each tooth through the gums with a minor surgical procedure and bond a small bracket to it. We then attach a small gold chain to the bracket that loops over an orthodontic appliance attached to other teeth. The appliance will exert pressure over several months to pull the tooth into proper position.
If successful, your child will gain the use of these important teeth and a more attractive appearance. But don't delay — this desired outcome will become much harder if not impossible to attain as their teeth and jaws continue to develop.

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.
“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…
For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.
When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.
A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.
But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.
Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!
