Similar in color and texture to natural teeth, the fillings are less noticeable and much more attractive than silver (amalgam) fillings. Composites are not only used for restoring decay, but are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.

The Procedure:

After the tooth is cleaned from decay or an old filling, the composite material is placed in layers using a light specialized to harden each layer. The final surface is shaped and polished to match the tooth.

Advantages:

White fillings come in a range of shades so they can be matched to the color of the existing teeth. The white filling material is strong and durable, and since it bonds to the tooth structure, it strengthens the tooth rather than weakens it as the silver (amalgam) filling does. Also, less tooth structure needs to be removed when placing a white filling than when placing a silver one.

Disadvantages:

The composite material is more expensive than silver fillings, and the restoration is more difficult and time consuming to place.

Alternatives:

Silver filling can be a cheaper alternative when money matters. In cases of extensive decay, inlays, onlays or crowns are the only alternative.
