Sharon -
Could it be related to your obturator? I know that my teeth (on the side with the obturator wires) ache from time to time, and I've chalked it up to wire pressure...I did go to my dentist with this complaint last year, and he took xrays and did a thorough check of all my teeth and could find nothing. Eventually, the aches went away.
Good luck with this -- I hope everything turns out okay!
