Bone is an essential component of our oral health. Unfortunately, when a tooth needs to be extracted, the supporting bone can be compromised and ultimately lost unless steps are taken to prevent the loss. Bone grafting involves packing bone granules into the empty tooth socket to maintain bone height, width and volume. The bone granules can be from cadaver bone, animal bone or from another area of your mouth. Ultimately, after 4-6 months, the grafted bone is your bone allowing the site to be used for future dental treatments such as implants.
