The gum above the tooth has also become sensitive. When I had the
heat sensitivity, it seemed to spread like a
wave of pain deep in the tooth. I went to the dentist the other day and had an x-ray done and he didn't find anything. He advised me to have another dentist examine it and have a deep cleaning and have them put an antibiotic in the deep crevice between the two back teeth to heal what he thinks is a gum infection problem. I am now taking 500mg of Cipro which I have on hand.
