6 years ago I went to the dentist he put a white plastic thing in my mouth told me to bite down and it hurt so bad and I was told I had a cracked tooth and needed a crown. So I had a crown put on. This did not aleviate the pain. A few years later I had a root canal done by an endodontist who drilled a hole through the crown. I had 4 canals and not the typical 3. After this the pain did not go away it has been 2 years since the root canal. My xrays come back good no signs of problems.
How is it after 6 years I still have pain in the same tooth?
I still have part of my tooth under the crown Could it be that my tooth that remains is still cracked?
I am having a pulsating throbbing toothache that will not go away.. I need help, advice, suggestions. PLEASE
