Hi doc: with greetings of the day: I am 57yrs male, had rct for upper left last tooth from mds doc. She made vent on three places taking 12 painful sittings & two were successful she said. Did temporary filling & asked to come once pain subsists. As there was repeated pain, even after 4 months, doc said rct has failed & hence redo the rct or extract. Another mds was appraoched. He took omr(mouth xray) & referred to a) facial surgeon, took head scanning for possible sinusus & found nothing b) another visiting rtc specialist-a friend of him for opinion. The doc makes temporary filling every time I complain of pain. In the meantime, I complained of jaw pain & shoulder pain but ignored saying it is not related to them. Finally, had heart attach & also diagnosed diabetes & under treatment. I did not find solution yet with mds docs past one & half year. Yesterday I was again advised for temporary filling. Appreciate your advise please. Regards.
