Teeth or Sinus: The symptoms that you describe could be caused from tooth problem or sinus inflammation/infection. The cause can be determined but it requires a dentist to evaluate you in person with the help of x-rays and a clinical exam along with a medical and dental history. We can't and shouldn't explain over the internet how you self determine a differential diagnosis.

Could be either: your upper teeth sit in the wall of the maxillary sinus that is beneath the cheekbone. They could be the source of infection, or the pain could be referred to them by a sinus infection. Teeth not sensitive makes it seem more like sinus. Warm Xlear rinse could help. Three weeks is a long time and infections in this location could become serious. You probably need to have an exam/ x-ray done.
