In the past, dental cavities were filled with a mixture of metal alloys, also known as amalgam. Today, tooth-colored or composite fillings are a mixture of resin, glass or quartz and porcelain ceramics. These materials are resilient and long lasting. These fillings are colored to match the patient’s teeth and are practically invisible to the untrained eye. For aesthetic and/or medical purposes, these tooth-colored fillings can be used to replace old and worn dental amalgam, gold or other metal fillings.
While composite fillings have visual advantages, over time they can become discolored. Just like metal fillings, tooth-colored fillings can be set and cured in one visit to the dentist.
Tooth-colored fillings are priced similarly to metallic alloy. They are not as long-lasting as amalgam fillings, and may chip in certain locations of the mouth. The dentist will discuss filling material options and recommend options based on the patient’s medical and aesthetic needs.
