Q. I need an upper left premolar and adjacent molar extracted. I am keen on getting implants to replace these teeth. My dentist offers implantology, but he has only placed 40 implants so far (with 100% success). I trust him and consider his work very good, but would I be better to look for a dentist who has placed hundreds or even thousands? He assures me that he would be mentored throughout by a more experienced surgeon.
