Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.
What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!
Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.
If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.
For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.
Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.
Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.
So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.

Like other living tissue, your teeth can feel. Dentin, the layer below the enamel, houses fluid-filled conduits that transmit temperature or pressure sensations to a nerve network within the tooth’s inner pulp. It’s so effective that incoming sensations must be buffered — “toned down”— to avoid a painful overload of the nerves. The enamel above the gum line and a bone-like substance called cementum below help do this.
Unfortunately, if teeth lose this protection they can become hypersensitive. This can cause a flash of sharp pain while eating or drinking something cold or hot or just biting down.
There are a number of causes for tooth sensitivity, any of which can influence how we treat it. While you’ll need a dental exam to know for sure, your hypersensitivity will more than likely stem from one of these 3 problems.
Periodontal (gum) disease. This is an infection caused by bacterial plaque, a thin film of bacteria and food particles that accumulates on the teeth due to poor oral hygiene. The inflamed gum tissues weaken and detach from the teeth, causing them to shrink back or recede. This leaves the cementum unprotected, which easily erodes and exposes the dentin to acid and bacteria — and hypersensitivity. Clinically removing the plaque helps the affected gums heal. In extreme cases, the gums may need surgical grafting to regenerate.
Overaggressive brushing. While a lack of oral hygiene can contribute to gum recession, ironically too much hygiene — brushing too hard for too long — can damage your gums and cause them to recede. Brushing really doesn’t require a lot of elbow grease — a gentle scrubbing motion over all tooth surfaces is sufficient to remove plaque. Fine-tuning your brushing will help your gums to recover and heal.
Mouth acid. Although quite strong, enamel has one formidable enemy: acid, which can erode enamel and expose the dentin. Over-indulgence in acidic foods and beverages can make your mouth more acidic; more likely, though, bacterial plaque will again be the culprit, because bacteria excrete an acidic waste product. You can reduce mouth acid with daily brushing and flossing and consuming less acidic foods and beverages.
