I went to the dentist two months ago to have one of my back molars checked. It was aching for a week. The dentist said the tooth was very decayed but he will try to save it through a root canal treatment if I want to. I agreed and he performed the root canal on that day.
Shortly, after I got the filling, I got a swelled lymph node in the right side of my neck and the tooth was hurting at the same time. After a week, the swelling was gone but the tooth pain remained. After about two weeks, I again had a swollen lymph node. I also noticed that the tooth hurts with anything hot and cold even with air. The next day, I woke up with headache and fever.
Is it time for the tooth to go? The dentist would only be able to see me after a month and I can’t go elsewhere because of insurance. What should I do while I wait for my appointment? Please help!
Thanks.
