Hello. I've had conflicting advice about the desirability of restoring the lower left second molar with an implant following extraction. I've been told that I would need a bone graft in this area but that this would be performed at the time of extraction (btw, extraction due to two failed root canals due to very negligent dental treatment and my previous dentist has agreed to pay for any work I need as a result of this).

However, some dentists suggest that it is not necessary to restore a tooth in the LL7 area and that the risks (difficulty of reaching the area, possibility of nerve damage etc) outweigh the benefits. Could you let me know your opinion please (cost is not too much of an issue for me and I'm interested in what would be the HEALTHIEST thing for my mouth and general body - I'm 31 and overall physically very fit). I'm having difficulty dealing with all these conflicting views!!!!!

Many thanks.
