Worried About Bone Graft

Jane, a dental implant patient, ask us:

I am getting two dental implants soon. Tooth # 29 has to be extracted, and tooth # 30 has been missing for many years. The dentist told me that I would need a bone graft done in # 30.

He said he’d be able to do the tooth extraction, the bone graft and the dental implant at the same time in one visit. Laser will be used. I will then have to wait for about 4 months, and have post operative visits to see the progress and determine when the crown and the abutment can be placed.

Does anyone have any advice about the bone graft? I am terrified of the idea of getting the bone graft, as I have heard quite a few stories that were not so good. What kind of graft should I be getting? What should I be looking out for? Why do these grafts sometimes fail? Any professional help in alleviating my anxiety would be much appreciated. Thanks very much.
