Composite fillings, also referred to as a resin fillings, are commonly used to repair broken, chipped or decayed teeth. The material for composite fillings is also used to reshape teeth in order to improve the appearance of a smile. Composite fillings can be color matched to existing tooth surfaces, creating a natural look. This is especially important when selecting the material to be used for highly visible teeth.

Composite fillings are formed from a mixture of plastic and glass used to replicate the look of natural teeth. Before a filling is placed, decay is removed and the tooth is prepared. The tooth-colored resin filling material is then bonded onto the tooth in layers and hardened by exposure to a special light. The composite is then shaped to ensure a good fit and polished to prevent wear.

Composite fillings have become a popular choice over the older metal amalgam fillings for many reasons.
