Do Amalgam Fillings Leak?

As previously mentioned, metal amalgam fillings will eventually leak. Fractured fillings mean that the mercury in the filling could be leaking out. Fractured fillings also mean more bacteria can get into the healthy part of the tooth causing a larger cavity.

How do I know if my amalgam filling is leaking?

If you notice that your teeth are darkening, it may be the result of the metal leaking out of the filling and into your tooth. You may also feel soreness, or notice that your filling can “give” under pressure. Both are symptoms of a failing amalgam filling.

When should amalgam fillings be replaced?

Metal amalgam fillings are designed to last for about ten years. At that point there's a good chance that the cement holding it in place is partially dissolved, which can make the filled tooth susceptible to decay from within! If your metal amalgam filling is over ten years old it's definitely time to replace it!
