If you have never had a cavity, congratulations! If you have had one, you are not alone. About 78% of us have had at least one cavity by the time we reach age 17, according to a 2000 report by the U.S. Surgeon General. Fortunately there's a time-tested treatment for cavities: the dental filling.
Fillings do just what the name implies — seal a small hole in your tooth, i.e., a cavity, caused by decay. This prevents the decay (a bacteria-induced infection) from spreading further into your tooth and, if untreated, continue on to the sensitive inner pulp (nerve) tissue located in the root canal. Should that happen, you would need root canal treatment.
There are a variety of materials used to fill teeth these days, but the process of filling a tooth is similar regardless. The first step is a clinical exam of the tooth with x-rays, to determine the extent of the decay. Then the decayed area of the tooth is removed, usually with a handheld instrument such as a dental drill. Of course, your tooth will be anesthetized first, so you won't feel any discomfort. If you normally feel nervous about receiving numbing injections, it's possible that taking an anti-anxiety medication or using nitrous oxide can help you feel more relaxed. After removing the decay, the remaining tooth structure is roughened or “etched” with a mildly acidic solution; then translucent cement is applied to bond the tooth and the filling material together.
Tooth-Colored Filling - Composite
A popular choice for those who don't want their fillings to show, composite is a mixture of plastic and glass, which actually bonds to the rest of the tooth. Composites are more expensive than the low cost fillings such as amalgam fillings, and the newer materials can hold up almost as long. Less drilling of the tooth is necessary when placing composite as compared to amalgam.

What to Expect After Getting a Filling
The numbness caused by your local anesthesia should wear off within a couple of hours. Until then, it's best to avoid drinking hot or cold liquids, and eating on the side of your mouth with the new filling. Some sensitivity to hot and cold is normal in the first couple of weeks after getting a tooth filled. If it persists beyond that, or you have any actual pain when biting, it could signal that an adjustment to your filling needs to be made. Continue to brush and floss as normal every day, and visit the dental office at least twice per year for your regular checkups and cleanings. And remember, tooth decay is a very preventable disease; with good oral hygiene and professional care, you can make your most recent cavity your last!
