You and your dentist should decide together which filling material will work best for you. If you want one kind of material or wish to avoid a certain type, tell your dentist. He or she will advise you if the material that you want will work.
The most common materials for restoring (or filling) teeth are amalgam (sometimes called silver), composite resin (sometimes called plastic or white), gold, ceramic and glass ionomer. Each material has pros and cons. Some materials may better meet your needs than others.
It depends on the size of your cavity and its location. If your cavity is in a molar, for example, the filling will receive a lot of biting force or stress, so a strong material is needed. If it is in the front of your mouth where there is less biting force and people will see it, a different material may be better.
