that touch the tooth cause extreme pain making it hard to
eat. It is not cold sensitive
at all. I have not gone back to
the dentist since the sensitivity has come back, I feel they won't know what to do again. The x-rays showed no cracks, my gums are very healthy, only 2 other cavities in 29 yrs. No prior dental work ever besides this RC. I have NO sinus or ear problems, no pain in my jaw, we tried antibiotics prior to the 2nd root canal, but that didn't help.
