my dentist of 15 years turns out to have let me bang a 30 year old #9 platinum crown bang into my head for 6 years after referred pain to the ear. 2 Specialist finally admitted his neglect. I have taken every vitamin and test you can.. I figured it was that tooth, but my blind dentist stated everything was ok. because of the cronism within the community, it took time to find an honest dentist, the tooth is now removed, and pain is better but still unbearable
