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 center of the tooth. 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 can help you feel more relaxed.
There are two broad categories of dental fillings: metal fillings and tooth-colored fillings. Each may offer particular advantages and disadvantages in certain situations.
Amalgam — The classic “silver” filling in use for more than a century, dental amalgam is actually an alloy made up of mercury, silver, tin, and copper. The mercury combines with the other metals in the amalgam to make it stable and safe. These fillings are strong and inexpensive, but also quite noticeable. They also require relatively more tooth preparation (drilling) than other types.
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 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.
Disadvantages of Silver fillings:
Silver fillings have some drawbacks. los edges of the silver filling can wear down, become weak or break. This results in the tooth not being protected and lets cavities get started once again. With age, the metal of a silver filling expands, contracts, and can split.
Silver fillings can corrode, leak and cause stains on your teeth and gums.
Some people choose to have their silver fillings replaced with Tooth-Colored Restorations.
Advantages of Tooth-Colored Restorations
There are some advantages to tooth-colored restorations. Such restorations can be used in instances where much of the tooth structure has been lost. The tooth remains intact and stronger.
The result is a beautiful smile!
