I had a tooth pulled and now need a bridge. My dentist prepped the teeth for the bridge and in stalled the temp. I had a lot of pain after went back and he said I need a root canal done on one of the prepped teeth. went home and still had pain went back and now he says I need a root canal done on both of the prepped teeth. I never had any problems or pain with those teeth. Did he cause the problems when he prepped the other teeth for the bridge? Shouldn't he have known before if I needed the root canals done, and wouldn't there have been an issue with those teeth before he did anything?
