Back molar pain, painful blister on molar. X-ray done. What could be the reason?
Patient: Hello, I have seen a dentist for my back molar being in a lot of pain. There were no restorations on the tooth and the dentist did xrays and said there was nothing wrong and dismissed me, three days later I went to the emergency room and they found nothing to be wrong that they could find without a dentist on staff, I have now dwveloped a very large and painful blister stemming from the tooth that had origionally caused me pain and it concerns me a lot what could be wrong?! Doctor: Hi, After reading your symptoms i understand that it is related to your wisdom tooth and there is no caries(bacteria in tooth) as your dentist didnt find anything on xrays. Abnormal position of the wisdom tooth and the gum covering it can cause sever pain. assuming it is the wisdom tooth, it is not unusual or rare so you should not worry too much. Due to the tooth being at back and malpositioned food lodgement occurs resulting in infection and swelling of the gum tissue in the area, which leads to ulceration due to improper biting while eating resulting in pain.  Warm saline gargles(3-4 times/day) along with an antibiotic course with a painkiller will help you temporarily. I would strongly advice you to visit your dentist to identify the problem and treat it accordingly. Regards
