s the tooth next to the crown, but the dentists cannot figure out the problem (even with Xrays), whether it may be a cavity in
that next tooth, an infection in
the root canal
, a nerve, or what one dentist suggested -- that the filling in that next tooth is old and is pressing on a nerve.
He told me I may have the same problem, and filed down the filling some. It helped me for a while, but I too have discomfort (not actual pain) when I chew on that molar area.
