Six weeks ago I had a bone graft (from my own bone) for a front lower tooth, that was pulled last year, to prepare for an implant. I quit smoking for almost 3 weeks, but did start again. I know I shouldn't smoke, but I also had some other serious upsets in my life which made it very hard for me to quit at this time. Anyway, my question is, how long does it take before the bone graft start to attach to your own bone or start to work or heal? Was the 3 week period that I was not smoking enough time for it to at least start to attach?
