My jaw swelled up and I had to have the tooth
removed. This required me to get a bridge. The tooth
for the back part of the bridge had a crown on it with a previous root canal from about 10 years ago. I had never had any problems with this tooth. Once the bridge was placed, I had severe sensitivity and pain from the back tooth. I've gone to the dentist several times and he always makes some excuse as to why it is hurting. Once, there was cement in the gum line.
