Hi folks I am male and 67 years old. I was diagnosed with Diabetes type 2 in January 2017. A Question for the community? Has anyone suffered from toothache from hell? In March of this year I felt a sharp pain in my lower jaw back teeth on the left, every time I ate or brushed my teeth? New that I had a broken tooth in that area which was seen by Dentist many years ago and repaired. So saw dentist and renewed filling, and has been ok ever since. But the beginning Of June this year noticed that my upper jaw back teeth on the same side became sensitive whilst eating and brushing teeth. The sensitivity became very acute and started to really hurt whilst eating and brushing. Made appointment with Denist usual inspection with x ray etc but nothing found? I should say by now eating or brushing teeth became a nightmare as pain would last from a few seconds to 10 plus minutes. Could this be the Metformin reducing my Ph levels and driving the acidity in my mouth up as this only happens with food or brushing teeth. Again the PAIN is pure agony? Anyone had similar issues with teeth sensivity. Have stopped taking Metformin as of today as I feel that 1000mg seems excessive?
