Composite restorations are the typical ‘white fillings’ we’ve all become familiar with. They are placed directly into the prepared tooth, hardened with a light, shaped and polished. Drawbacks include the fact that they only last 3 to 10 years depending on the size of the filling, location in the mouth, and heaviness of the bite. Composites can also be sensitive for a while after being placed.
Composite restorations are used routinely today where silver-mercury fillings were used in the past. Most people are pleased to have nice new white fillings when the old metal fillings need replacement.
