Do amalgam fillings weaken teeth?
Amalgams break teeth A major problem with amalgam fillings is that they significantly weaken the teeth they are in. The larger and older the filling, the weaker the tooth becomes. After years of wear, many amalgam-filled teeth develop deep structural cracks adjacent to the fillings.
