No, that is one possible reason with a filling, but surgery
and extractions can heal over leaving an abscess and that
could be a very painful problem. When my wisdom teeth were
removed, the roots actually penetrated the sinus cavities.
For several weeks I could have salt water run through from
my mouth to my nose by dipping my head. This was not a
problem flying, it was even more venting. But I would want
to have a flight test before I was the only pilot on the
plane.

Gas would be reabsorbed if enough time passed, but if there
was any gas it would expand during a climb faster than it
would be absorbed, think the bends.
