Dental Filling

What is a Filling?
A filling is a way to restore a tooth damaged by decay back to its normal function and shape. We first remove the decayed tooth material, clean the affected area, and then fill the cleaned out cavity with a filling material.

By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).

  • Composite (plastic) resinsآ are matched to be the same color as your teeth and therefore used where a natural appearance is desired. The ingredients are mixed and placed directly into the cavity, where they harden. Composites may not be the ideal material for large fillings as they may chip or wear over time. They can also become stained from coffee, tea or tobacco, and do not last as long as other types of fillings generally fromآ three to 10 years.
  • Porcelain fillingsآ are called inlays or onlays and are produced to order in a lab and then bonded to the tooth. They can be matched to the color of the tooth and resist staining. A porcelain restoration generally covers most of the tooth. Their cost is similar to gold.
