Traditionally all cavities have been filled using metal or amalagam material. While effective, there are a number of drawbacks to these types of fillings, including the presence of trace amounts of mercury, as well as that the fillings are visible when a person opens their mouth. In addition, these fillings can often crack or otherwise fail over time, resulting in the filling needing to be redone. Today most dentists prefer to use composite resin fillings for a number of reasons, including the lack of metal, improved appearance, longevity, the ability to easily work the materials and the versatility of the material.
One of the benefits of composite resin fillings is that the material does not include any metals such as mercury in the material. In addition, composite resin fillings are white in color and the dentist has the ability to shade the material to match the color of the tooth. It is virtually impossible for the untrained person to tell if someone has a filling in the tooth. Also, composite tooth colored fillings are very durable given the nature of the material and it is rare for a composite resin filling to fail.
A vast majority of dentists also prefer composite resin fillings, because it is very easy to work with. It does not set until a special light is applied to “cure” the resin. Once it is hard, it is easy to shave any excess material using a dentist’s drill. In many cases it is also possible to easily repair a broken or chipped tooth using the resin, which could eliminate the need for a dental crown.
Composite resin filings are state of the art and are much better than traditional amalagam fillings!
