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!

Home whitening kits are a popular way to turn a dull smile into a dazzling one. But these self-applied products only work for teeth with outer enamel stains — if the discoloration originates inside a tooth, you’ll need professional treatment.
Known as “intrinsic staining,” this type of discoloration most often occurs within a tooth’s pulp or dentin layers. There are a number of causes like tooth trauma or tetracycline use at an early age. A root canal treatment used to remove infection from deep within a tooth can also cause discoloration: sometimes blood pigments left after tissue removal or the filling materials themselves can stain a tooth’s interior.
Intrinsic staining can often be treated by placing a bleaching agent, usually sodium perborate, into the tooth’s pulp chamber. But before undertaking this procedure on a tooth that’s undergone a root canal treatment,Â we want to first ensure the filling is intact and still adequately sealing the tooth from infection. We also want to make sure the supporting bone is also healthy.
If all’s well, we access the pulp in the same way as the root canal treatment, and preferably through the same access hole. We then clean out the pulp chamber of any stained matter and then ensure the root canals remain filled and sealed off from the pulp chamber.
We can then place the bleaching agent into the pulp, a process that will need to be repeated every three or four days to achieve the desired level of brightness. After each session we place a cotton pellet over the opening and held in place with a temporary adhesive; we can easily remove and re-apply this covering during subsequent sessions. Once we’ve achieved the desired color change, we seal the tooth with a permanent filling and restore the access cavity with a tooth-colored composite resin material bonded to the enamel and dentin.
There are other options for an intrinsically stained tooth like veneers or crowns that outwardly cover the discoloration. Internal bleaching, however, is a more conservative approach that causes less alteration of the tooth. If successful, it can restore a stained tooth to a brighter, more attractive shade.

We all experience the occasional bout of bad breath from dry mouth or after eating certain foods. Chronic halitosis, on the other hand, could have an underlying health cause like periodontal (gum) disease, sinus infections or even systemic illnesses like diabetes. Anyone with persistent halitosis should undergo a thorough examination to determine the root cause.
If such an examination rules out a more serious cause, it’s then possible the particular population of bacteria that inhabit your mouth (out of a possible 600 or more strains) and your body’s response makes you more susceptible to halitosis. After feeding on food remnants, dead skin cells or post-nasal drip, certain types of bacteria excrete volatile sulfur compounds (VSCs) that give off an odor similar to “rotten eggs.”
In this case, we want to reduce the bacterial population through plaque removal, which in turn reduces the levels of VSCs. Our approach then is effective oral hygiene and perhaps a few cleanings — the basics every person should practice for good oral health — along with a few extra measures specific to chronic halitosis.
This calls for brushing and flossing your teeth daily. This will remove much of the plaque, the main breeding and feeding ground for bacteria, that has accumulated over the preceding twenty-four hours. In some cases, we may also recommend the use of an interproximal brush that is more adept in removing plaque clinging to areas between the teeth.
You may also need to pay special attention in cleaning another oral structure contributing to your bad breath — your tongue. The back of the tongue in particular is a “hideout” for bacteria: relatively dry and poorly cleansed because of its convoluted microscopic structure, bacteria often thrive undisturbed under a continually-forming tongue coating. Simply brushing the tongue may not be enough — you may also need to use a tongue scraper, a dental device that removes this coating. (For more information, see the Dear Doctor article, “Tongue Scraping.”)
Last but not least, visit our office for cleanings and checkups at least twice a year. Professional cleanings remove bacterial plaque and calculus (hardened plaque deposits) you’re unable to reach and remove with daily hygiene measures. Following this and the other steps described above will go a long way toward eliminating your bad breath, as well as enhancing your total oral health.
