Our teeth help to maintain bone density by a natural renewal process. This ensures normal bone growth and healthy tooth tissue. If you have been missing a tooth or teeth for some time, or if there was a past infection in the area, you may have lost some of the bone that supported your tooth. Bone grafting is the process by which we build up a thin or shrunken jawbone. If you are considering an implant but dental x-rays and/or CAT scan show that you have a thin jawbone as a result of bone loss, then a graft will be necessary.
If you require several implants then the amount of bone to be grafted will increase in proportion to the number of implants.
