What can i expect during bone grafting surgery?

Varies widely: How many teeth? For one to three teeth: less bleeding when grafting is done and the graft helps to stop the bleeding. Normally the dentist places a covering over the graft site and you will need to eat soft foods to help keep it in place. Normally you will be on an antibiotic and a mouth rinse may be prescribed. You should do better than if they didnt graft the site after the extraction.

Depends: It depends on the size of the bone graft placed. Obviously the larger grafts may require longer to heal and there may be more discomfort. However when grafting immediately following extraction there is very little pain and some discomfort for a day or two. Bone grafting is very predictable.
