After decay or damage has been removed, a tooth filling protects the tooth and helps maintain its shape while ensuring an even biting surface. Without it, a cavity will continue to grow and ultimately cause the loss of the tooth and other dental issues. The material you and your dentist choose for your filling is important. Here are the four most common options.

A Guide to Tooth Filling Materials

1. Composites

Composite fillings are made of resin and plastics. They are soft when applied to the tooth, which allows them to be fitted to the exact dimensions of the space to be filled. Once they've been fitted, they’re hardened with a high-intensity blue light. Composites come in natural colors, so they fit in well with the shade of the surrounding teeth.

2. Amalgam

Amalgam fillings are comprised of silver, mercury, and several other metals. The metals are mixed to combine a putty that quickly hardens once it’s placed in the tooth. Amalgam fillings are cost-effective and long-lasting, with a life span of 15 years or more.

3. Porcelain/Ceramic

Ceramic fillings, made of porcelain, involve a multi-step application process. First, a mold of the tooth is taken, then the filling is custom-made to fit the contours of the tooth. At the next appointment, the filling is affixed over the decayed or damaged area. Porcelain fillings are the most natural-looking option and have strong stain-resistant capabilities.

4. Gold

Gold tooth fillings work like porcelain in that they are custom-made from an impression of the tooth. While it’s typically the most expensive type of filling, gold does have some benefits that others on this list do not. They boast long life and durability—they can last for more than 20 years and are extremely resilient.
