What is a White Dental Filling?

When you smile or speak animatedly, you show more than just your teeth; you also show all of the dental work present in your mouth. For many people, this means the metal of one or more fillings flashing against the pearly white color of the teeth around them. For many others, however, their dental fillings aren’t noticeable, since they’re made from tooth-colored composite resin instead of conventional metal amalgam. Often referred to as white fillings, the resin restorations can offer a more discreet and secure solution to treating infectious tooth decay.

Composite Resin vs. Metal Amalgam

How do white fillings compare to their older, metal counterparts?


Naturally, metal fillings can withstand a greater amount of pressure than composite resin, which is a mixture of acrylic and glass-like particles. Because of this, Dr. Smith may sometimes recommend amalgam fillingsto restore back teeth, or molars. Nevertheless, white fillings can be bonded to your tooth’s structure, improving the tooth’s structural integrity by holding the tooth together.


As their name suggests, white dental fillings can be custom tinted to match the specific color and shade of your teeth, making them invisible once they’ve been placed and polished. The cosmetic appeal of dental resin is so effective that it can be used as a purely cosmetic dental treatment, known as dental bonding, to improve a tooth’s appearance. Severe tooth stains, chipped or uneven tooth edges, or teeth that appear too short can usually be corrected with a cosmetic dental bonding.


While all dental fillings are built to last, metal fillings are better suited for handling larger amounts of pressure for longer periods of time. Unfortunately, metal fillings may fail due to shrinkage or expansion in cold or hot temperatures (respectively). The longevity of metal and white fillings is different for each patient and depends on a number of factors, including how well you care for them, but most of them can last up to 15-20 years before needing replacement.
