2. What Is a Composite Tooth Filling?

Composite fillings, also known as tooth-colored or white fillings, are made from a mixture of plastic resin and fine glass particles. Unlike traditional amalgam (silver) fillings, composite fillings blend seamlessly with your natural teeth, making them a popular choice for visible areas.

Key Features of Composite Fillings:

Aesthetic Appeal: Matches tooth color.
Bonding Strength: Chemically bonds to the tooth.
Minimally Invasive: Requires less tooth removal than amalgam.
Mercury-Free: Safe for long-term use.
