White fillings: Yes the metal fillings can be replaced with white fillings. We usually do not replace them unless they need to be replaced because of decay of fractcures but you can request they be done. If the fillings are really large they will need to be replaced with a crown ( tooth colored ). The latest generation of white fillings last as long as metal fillings.

Discuss with DDS: Composite (white) fillings are the most widely used dental filling material today. However, you should discuss this with your dentist for your individual needs before the filling is placed in your tooth.

Cavities: White fillings are initially soft and they adapt to any shape of the cavity and look normal and do not darken the tooth over time. They wear down quicker. Metal fillings are comprised of a mixture of copper, silver tin and mercury. They tend to tarnish and sometimes do not preserve the natural tooth structure. Talk to your dentist about replacing your old fillings and which is better for you.
