Crowns provide support for teeth that are otherwise comprimised. This is accomplished by surrounding the weakened tooth with
a tough restoration, similar to a cast on
a broken bone. The main difference is that
a crown in permanent. Crowns are made of
various materials. The most common have a
metal substructure covered by tooth colored
porcelain that is matched to your teeth.
Others are made of all porcelain, and occasionally
all gold crowns are still fabricated. Your
dentist will determine which is best for
your particular situation.
