What is a crown?

A crown is a laboratory fabricated custom made tooth that precisely fits over a broken natural
tooth to hold it together and return it to normal function and appearance.  Up until recently,  crowns were
made out of gold or porcelain, or a combination of a gold understructure which is completely covered by
tooth colored porcelain to match your other teeth.  

Now in most cases our office uses new metal free crowns made of either dilithium silicate, or zirconia.
These crowns are extremely life-like in appearance and function and are very strong.

Zirconia and dilithium silicate (Bruxzir and E-max) crowns are often so natural in appearance that it is
difficult to tell them from your own teeth.  These crowns also require less drilling as more healthy tooth is

What will I experience during my crown appointment?

A topical anesthetic (numbing cream) is rubbed on your gum with a Q-tip.  Then, an injection of
local anesthetic is given into the numbed area.  If you are extremely nervous about your crown,
nitrous oxide (laughing gas) can be given, but is rarely needed.
After you are numb, 1 to 1.5mm, about 1/20 inch of enamel is removed around the tooth.  
An impression is taken of the prepared tooth and sent to the laboratory.  A temporary tooth is
then placed over your prepared tooth. One to two weeks later your new crown is bonded in
place.  A typical crown procedure on a back tooth is showed below.

A bridge is a replacement for missing natural teeth.  A false tooth or pontic, is connected to two or
more crowns, and is cemented in your mouth replacing the missing tooth.  With the high success rate and
comfort of implants, less missing teeth are being replaced with bridges and more with
