New advances in bonding, resins and ceramics have made tooth-colored
fillings that are strong and lasting a reality. Dental amalgam (silver), is
an economical option that is safe for most people except those few who have
a true allergic reaction to it. In some cases, amalgam can contribute to
tooth fracture, however.
With all of the questions about amalgam, many wonder if they should have
their silver fillings replaced. Removal of these fillings can cause
structural damage to your teeth, depending on the filling's size, and might
cause unnecessary expense.
