Sinus infection or tooth problem?
I really hope to hear from people. I had a crown ten years ago in an upper-left molar with no problems. Three weeks ago I started feeling extreme cold sensitivity in that one tooth and in my lower left teeth, could not drink cold water or eat food from the fridge. Warmth does not seem to bother it at all. Went to dentist; x-rays showed no need for root canal, was diagnosed with sinus infection. I have taken an entire Z-pack of antibiotics, seen my reg. doctor who prescribed Keflex and Mucinex D. Three weeks later I have just as much tooth sensitivity and sinus pressure. I am at the point that I just break down and cry the tooth pain hurts so much. Should I go to another dentist or does this really sound sinus-related? How long can the sinus infection last?
