Hi， Bryanna，
I think my case is very complicated!
I have tons of root canalled teeth，both front and back. I got to know root canal is very bad in the year 2012,since then I have had 4 extracted due to infection. I didn't follow my dentists advice to re do the root canal. But now I was wondering is it the correct to pull them out because I did a lot of research and get to know almost 90% extraction end up with cavitation,which is worse than root canal！even the ligament is removed. I'm planning to get another root canal molar extracted this year。But now very confused. I have another question, i find every time I have a single tooth removed, the adjacent tooth is always also a root canal one, I was wondering is it a factor to prevent the bone healing and since cause cavitation later?
