I really need help. I am 51 yrs. old and I have had about 12 root canals in my lifetime. I had a lot of decay
and large fillings, and I did this on the advice of a family member (who is a dentist--a very good one) to save my teeth. Now most of my teeth are crowns and, although, they look good, I am starting to have problems with needing to get root canals *retreated.* I had two in particular, large molars, that have caused me so much pain with pain shooting up to my ear.
