Hi, I had pain in last tooth due to cavity near the gum area. Dentist did temporary filling and asked to observe for 45 days after which he would do permanent filling. I still have pain sometimes in my tooth when I drink water after 3 weeks of filling. Should I go for root canal? Or can I avoid it as the pain is sometimes and goes with a pain killer. Can it have any affect on other neighbour teeth also if I don't go for root canal? this is my major concern.
