Crowns
If
a tooth is severly decayed, broken, or cracked we may suggest
an artifical crown be placed on the tooth. This should be
a painless procedure that takes two or three office visits.
If the
roots and base of the tooth are strong, we will prepare the tooth
for the crown by removing a portion of the enamel and dentin.
If the
tooth is severely decayed, or weak, then it may be necessary to
insert a post into the tooth to support the crown. In this
case, root canal therapy is performed, and then the post is bonded
into the cleaned out root.
Since
the crown must be carefully constructed to match the opposing
tooth and ensure a correct bite, several impressions of the teeth
are taken and sent to a lab which will construct the crown.
A temporary crown will be placed to protect the tooth until the
next appointment.
At the
next visit, the dentist will fit the crown over the old tooth.
After some adjustment it is cemented in place.
