Composite Resin Fillings (Tooth Colored)

Composite resin is a filling material designed for aesthetic dental restorations. Formulated to resemble the color of your natural tooth, composite resin is often used for filling dental cavities or for dental bonding front teeth.

Composite resin consists of glass or quartz filler added to a resin medium, which produces a tooth-colored filling. The invention of composite resin offers a substitute to the amalgam dental fillings we’ve grown so accustomed to. This plastic and glass mixture contains no metal and can be shaped to resemble a real tooth. Onlookers usually can’t tell that a tooth has even been filled!

There’s been a lot of discussion about whether composite resin is safer than amalgam. Throughout its 150 year history, there’s been no evidence linking amalgam to the diseases some say it causes. Amalgam is a stable filling material deemed safe by many public health organizations — it is much more likely you’ll obtain mercury from fish or polluted air than from it leaking out of silver dental fillings. But if you do prefer mercury-free restorations, speak with your dentist about your concerns.

For Your Consideration: Before you start replacing all of the silver in your mouth with composite resin dental fillings, keep in mind that it may not be for everyone. Here’s what you need to know about composite resin before you have any work done:

  • Not as durable or long-lasting as amalgam
  • Will need to be replaced every 7-10 years
  • May not be suitable for larger dental fillings
  • Procedure is more detailed and costly than amalgam restorations
  • Tooth-colored fillings are vulnerable to staining
  • May leak causing decay under the filling
  • May fracture the tooth as it cures over the first 24 hour period after placement
  • May prematurely wear causing your teeth to move
