Dental fillings: almost everyone has one or more in their mouth, but few people know the finer details of this common dental restoration. For example, do you know what your fillings are made of? Or how long the average filling lasts before it needs to be replaced? If you have metal fillings that are so old you cant remember when you got themyou may want to have them checked by your dentist to make sure they arent in need of replacement!

When tooth enamel is exposed to bacterial acids, it can become demineralized. If not treated promptly, demineralized enamel develops a cavity, or hole. Fillings restore holes in your teeth, by filling them up with a replacement substance to restore the structure of the tooth and prevent the cavity from growing larger.

Fillings may be made from either metal amalgam or composite resin. Silver and gold used to be popular metals for fillings many years ago but todays metal fillings are usually made from a combination of silver, tin, copper, and liquid mercury.

There is some concern about amalgam fillings because they contain small amounts of mercury, and mercury is toxic to humans. This issue has been studied in depth by the Food and Drug Administration (FDA), which determined that the mercury in fillings does not pose a threat to ones health. Because the mercury is not in a form that can be absorbed by the body, it does not pose any significant health risks in a dental filling. However, some people prefer to avoid metal fillings for this reason, just to err on the side of caution. Additionally, some countries have banned the use of mercury in fillings, but this is mostly to prevent the potential environmental risks posed by waste materials. (There is more danger from mercury being released into the environment from medical waste than there is from the mercury present in dental fillings.)

Depending on how well they are placed and how the tooth is used, fillings can last a very long time. However, they should always be checked by your dentist at your routine check-ups, to make sure they are not showing signs of failure.

On average, metal amalgam fillings tend to last about 12 years, while composite resin fillings last about 8 years. Both types of filling can cause problems in your mouth if they outlive their lifespan and are not promptly replaced. When metal fillings age, they have a tendency to expand, which may lead to the tooth becoming cracked by the pressure. Composite fillings, on the other hand, tend to leak as they age, which can lead to secondary decay if the cavity becomes exposed.

If you maintain a schedule of regular preventive visits, your dentist will already be keeping an eye on your fillings every time you take an x-ray or have your teeth examined. If they need replacement, we will let you know!

Root canal therapy is not the same as a standard dental filling, but it is similar. Fillings can only fill and replace tooth enamel. If decay or a crack reaches the inside of a tooth (beyond the hard enamel) the soft tissues (blood vessels, nerves, and other tissues) must be replaced with a different substance to restore the tooth. Root canals are often finished with a filling, but they can also be finished with a dental crown.

Many patients are pleasantly surprised to learn that we can easily replace metal fillings with composite fillings. If youve had metal fillings for several years, it may only take a single visit to have them replaced with more attractive white fillings.
