Hey everyone, im already missing tooth #2, but my tooth #3 the dentist says im probably going to need a root canal. (Long story short, im having massive migraines and xrays show my roots are in my sinus cavity which is probably causing ny migraines). My question is should i get a root canal and hope that that fixes the problem and hope to not have problems later on. Or should i just fet the tooth pulled, but ill then be missing tooth #2 & #3.
