Tooth ache?!
Question:
Tooth ache?
i was at the dentist just a month ago, got a few fillings done. one of my tooth started becoming sensitive to cold, or perhaps it was always sensitive, anyhow, recently, it started hurting like a throb on and off, and it hurts when i put pressure on it, like when i chew. what could this possibly mean, would the dentist have picked up the cavity under the already filled tooth if one existed?
Answers:
There could have been alot of decay in that particular tooth. Sometimes a tooth nerve can be irreversibly damaged even if the decay doesn't actually expose the nerve. If there is an old filling in a tooth, an additional cavity often times does not show up on an x-ray. The additive trauma of replacing the old filling may have also caused the nerve to be irreversibly damaged.This happens often. You may need a root canal.
