The issue with silver fillings is the way they weaken the structure of the natural tooth. The weakening of the tooth is due to the material expansion and contraction when coming in contact with extreme temperatures. Continual flexing may create microfractures, and the filling can crumble and leak over time. Besides that, there are concerns about the mercury content of amalgam fillings, a metal that can be toxic in huge amounts.

Composites are much better for teeth as less tooth structure needs to be drilled for their placement and the resin bonds to the natural tooth very strongly.

Placement of composite fillings is rather technique sensitive, and your dentist will thoroughly clean out the decay before completely drying the tooth. Next, they will gradually apply the filling material in tiny increments, curing it with a particular light. At last, the restoration will be shaped and polished and should be just about invisible.

Amalgam fillings typically can last up to 10 years before they begin to leak or fracture, so it’s possible yours could do with replacing.
