My upper back molar had a root canal done three years ago. I have been having mild pain in it for a couple of months now. The dentist sent me to an who said there is an infection right under the crown and he put me on antibiotics for seven days. He will redo the root canal when I finish the antibiotics.
I can't decide yet if I'll have the redone or if I should just have it pulled. Please help me make a decision. What is the chance that this tooth will not give me a problem again in the future if I will go with the expensive canal?
I look forward for your answer. Thanks a lot!
