If the endodontist only gives the Tooth
a 30% chance I think those are not very good odds. Yes the infection will be removed at the time of the extraction. I am very much in favor of implants and I restore them all the time in my office. It is a excellent alternative to cutting two adjacent teeth to put in a bridge. My first choice if you have to lose the Tooth
is the placement of an implant.The implant can be a life time restoration.
