I have no clue and I would be guessing.See your dentist asap.
I would recommend having a dentist take a look at it. It could be anything, and without an exam or xray it would just be a wild guess. Pain could relate to a dental abscess, grinding habit, cracked tooth, etc. There are a bunch of things that could be causing it.
thanks for writing back... ill do that , but it has to be nerve or a root problem , ive taken pain killers but still hurts
I had some part of a filling come out in a back molar and went to refill. Immediately after anes. wore off - that nerve pain you describe. It's been nearly 2 weeks, sedative filling and all; you touch one part of the tooth and youch. Feels like a nerve. So, was a nerve damaged? Root exposed? Dentist said tissue is healthy underneath (aside from the bad decay he refilled). Is root canal my only option?
