Decayed and damaged teeth require bio-compatible and long lasting fillings for the restoration of structure, function and aesthetics in most of the cases. Front teeth require filling materials capable of restoring aesthetics with less functional demands. Back teeth are involved in the mastication of food particles and heavy occlusion forces. Choice of filling teeth in the posterior areas of mouth is extremely important.

Dental amalgams are strong restorations and have good retention rate which is considered an important factor in such cases.

The American Dental Association (ADA) also has defended the fillings as having “established a record of safety and effectiveness.”
