Pain started about two weeks ago in upper right molar, which was also very sensitive to heat and cold. Went to my dentist, who found fine cracks in the tooth, removed a filling in that and the adjacent tooth and put a temporary dressing in both. She said if it didn’t work it would help to pinpoint the source of the pain. It’s now got much worse. At night I get severe pain in the parallel teeth on my bottom jaw too, which keeps me awake. The pain seems to be coming from the gums, which are painful to touch. I’m using clove oil but it only works temporarily. Aargh - so painful!
