One molar, which has a very large amalgam filling from a previous dentist, has a large crack and discoloration down one side of the tooth
. The dentist recommended a ceramic crown
(he has some device in his office which can make the crown while-we-wait). The tooth currently does not cause any pain.
The next tooth over also has a very large amalgam filling. The tooth looks healthy, but the filling looks old (its maybe 7 years old), and possibly needs to be replaced.
