In a healthy mouth, the bony tooth sockets cups and supports the teeth. But patients with periodontitis develop holes in the bones around the teeth, which leads to the formation of periodontal pockets and loosening of the teeth.
Many times after a tooth is removed, a bone graft is used to fill in the otherwise hollow area. A bone graft is similar to what the scaffolding does for a house. Your body will build new bone around this scaffolding and resorb the bone graft over time, replacing the hollow area with a solid area of bone.
Depending on the extent and location of the bony (osseous) defects, treatment may include osseous surgery, which reshapes the existing bone and is generally used to treat bone loss around multiple teeth. The alternative is regenerative surgery, which involves regenerating the lost bone, usually when defects are limited to one tooth.
