A composite filling is a tooth-colored dental restoration that's used to repair decayed, cracked, or chipped teeth.
Here's what happens during a root canal treatment:
A mixture of powdered glass and plastic resin.
Designed to blend in with the natural color of your teeth.
Can be used on front or back teeth, and can also be used to repair other dental issues like discoloration.
Can last 5–12 years, but may need to be replaced more often than amalgam fillings.
Can cost more than amalgam fillings, and may not be covered by some insurance plans.
A dentist removes the decayed or affected part of the tooth, then places the filling in its place. The filling hardens immediately after a blue UV light is applied to the tooth.
Some composite resins contain Bisphenol-A (BPA), a chemical that may be associated with health issues. You can discuss the materials being used with your dentist to reduce the risk of exposure. You should also communicate any allergies or other health issues with your dentist.
