Dr. Graham I have two molars (teeth 14 and 15) upper back left side that had fillings done a year and a half ago. The dentist had to put root caps on because he drilled all the way down to my root. They never healed properly and have always given me trouble. Pain has been getting worse in the last few weeks. I might have to get a root canal. In your opinion and with what you know so far, do you think a root canal is necessary or could I heal it with fasting? What is your opinion of root canals in general? I found a biological dentist that uses more compatible material but it is still a root canal nonetheless. I would love your opinion and any advice you have. Thank you so much.
