DINA GIESLER:
The best way to describe a crown
is it's a cap that we put
on a tooth,
and it's probably the best
procedure
we have to save a tooth.
A patient
needs a crown when the tooth has
been compromised with, you know
obviously, a big cavity
or a root canal
or a large filling that takes up
more than 3/4 the size
of a tooth.
If you were to take out
an old filling,
usually there's
just a shell left.
So that's a very weak
substructure,
so a crown is actually something
that covers and protects
the tooth.
