Dentists use different fillings depending on the type and location of the tooth, the size of the damaged area, the extent of the decay, and the type of restoration needed. Molars are often filled with amalgam (silver) or composite (tooth-colored) fillings, while premolars may be filled with either composite or amalgam.
Dentists will usually fill canines with either composite or gold, while the anterior teeth are usually filled with composite. Fillings can also be used to repair cracked or broken teeth.
