How Do White and Silver Fillings Compare?

Posted in Fillings

White fillings are made of a composite resin material. Some dental offices use this material exclusively. Silver fillings are made from an alloy of metals, such as:

  • Liquid mercury
  • Silver
  • Tin
  • Copper

What are the differences between these two types of fillings?


Metal fillings tend to be placed faster than white ones. This coupled with the fact that the materials are cheaper for placing metal fillings make them more affordable than white ones. Many insurance companies prefer to only pay towards the cost of a metal filling and might expect the patient to cover the difference for the more costly ones.


This one is pretty obvious! It’s essentially a matter of personal choice whether or not you want metal fillings showing when you smile. The white ones will blend in and not be nearly as noticeable.


How long a filling lasts depends primarily on how well you take care of it. Proper brushing and flossing reduce the chances that a new cavity will develop around the filling. Metal fillings can hold up better to the forces of chewing. White fillings have the potential to fracture, but this is because they are more structurally similar to your tooth than metal ones are.


No definitive studies have shown that having amalgam fillings in your mouth puts you at risk for mercury poisoning. However, some cautious patients prefer to err on the side of safety and opt for composite restorations. The white fillings contain no mercury.

Which kind of filling is right for you?

You’ll have to talk about that with your dentist when the need arises. At least you’re prepared with some information on the most common restorative options!
