i have a question on behalf of my mom, she's 65 years old. The dentist told her that almost all of her teeth on her upper jaw will be extracted and every tooth will be bone grafted before they give her dentures. is bone grafting really necessary before dentures or can we get away without it? It will cost us $330.00 per tooth and they need to remove 8 . It's really expensive so is it really necessary or can we do away with it?
