Can Composite Fillings be Whitened?

Posted in Teeth Whitening

A lot of people want to know if their white dental fillings can stain or be whitened. Since the material is a matched to the rest of the tooth, it’s an important topic to discuss. Not only are composite fillings necessary for restoring teeth, they’re also essential to maintaining pleasing aesthetics when you talk or smile.

The fillings themselves cannot change color or be whitened. If you decide to whiten your teeth, the tooth enamel will become whiter but the filling itself will remain the same shade. There are many different shades of composite available and each one is carefully selected to match your natural tooth. If you decide later on that you want your natural tooth to be a different color, then the filling will need to be replaced and re-matched to the tooth after your smile is whitened. If whitening is in your future, you might want to consider completing it before having a new filling placed, that way it will match your treatment investment.

Over time it is possible for the margins of restorations to become leaky. Bacteria and stain can seep into the margin around the filling, between it and the tooth. You might notice this as a dark line around your tooth-colored filling, making it stand out from the rest of the tooth. If this is the case, it’s time for you to talk to your dentist about replacing the filling. Not only will this correct the aesthetic concern, it will also prevent new cavities from forming underneath your existing filling. Again, it’s worth considering whitening before having the filling replaced, especially if whitening is something that has been on your mind.
