I am in the midst of phase I of a reconstruction of my teeth due to bruxism and/or TMJ. After the 4 hr. appt to prepare my upper teeth for
the impressions, my dentist decided to fix a problematic tooth
not specified in the phase I project. He found I needed a root canal, which he did. During the procedure, he said my "devital" tooth
had abscessed and he worked on that.
