Amalgam Fillings

Until recently, dentists filled and sealed cavities exclusively using
a silver and mercury amalgam. Unfortunately, these fillings (or
restorations) often weaken teeth due to the large amount of the
original tooth that has to be removed.

Modern dentistry has increasingly turned to composite fillings as a
strong, safe and more natural looking alternative. Composite fillings
utilize a soft white plastic substance that includes a hardening
agent.

Replacing large fillings on back teeth often require a stronger and
properly contoured restoration. These are called inlays or onlays
depending on their size. These restorations need to be custom-made at
an off-site dental lab and two visits may be required.
