1 side of face swollen, pain in cheek by jaw & up to eye causing constant headache denisits said not teeth probably to do with sinus (2 months)?

Advice: This really requires a complete medical and dental history along with x-rays and a personal clinical exam in order to try to determine cause. Having said that, I would do two things- first consult another dentist who comes highly recommended (General Dentist and\or Oral Surgeon) AND also consult a physician (preferably an ENT Specialist).

ENT: If dental infection has been ruled out, time to sEe an Ear/Nose/Throat specialist.

See ENT for eval: If this is not a dental related issue that you have been experiencing, you should see an ENT for evaluation and diagnosis.
