While out with friends one evening, you take a bite of ice cream. Suddenly, pain shoots through your teeth. It only lasts a second, but it's enough to ruin your good time.
This could be tooth sensitivity, a painful reaction to hot or cold foods. It often occurs when the enamel in prolonged contact with acid has eroded. Acid is a waste product of bacteria found in plaque, a thin film of food particles that builds up on tooth surfaces due to inadequate brushing and flossing. Enamel normally mutes temperature or pressure sensation to the underlying dentin layer and nerves. Loss of enamel exposes the dentin and nerves to the full brunt of these sensations.
Sensitivity can also happen if your gums have shrunk back (receded) and exposed dentin below the enamel. Although over-aggressive brushing can often cause it, gum recession also happens because of periodontal (gum) disease, a bacterial infection also arising from plaque.
The best way to avoid tooth sensitivity is to prevent enamel erosion or gum recession in the first place. Removing accumulated plaque through daily brushing and flossing is perhaps the most essential part of prevention, along with a nutritious diet low in sugar and regular dental cleanings and checkups.
It's also important to treat any dental disease that does occur despite your best hygiene efforts. Gum disease requires aggressive plaque removal, especially around the roots. While receded gum tissues often rebound after treatment, you may need gum grafting surgery to restore lost tissues if the gums have receded more deeply. For enamel erosion and any resulting decay you may need a filling, root canal treatment or a crown, depending on the depth and volume of structural damage.
While you're being treated you can also gain some relief from ongoing sensitivity by using a toothpaste with potassium nitrate or similar products designed to desensitize the dentin. Fluoride, a known enamel strengthener, has also been shown to reduce sensitivity. We can apply topical fluoride directly to tooth surfaces in the form of gels or varnishes.
Don't suffer through bouts of tooth sensitivity any more than you must. Visit us for a full exam and begin treatment to relieve you of the pain and stress.

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!
