Jawbone health: Optimum jawbone health is perhaps one of the most important factors affecting the candidacy for dental implants. When a tooth is extracted, small bits of the jawbone will also be removed along with the tooth. This can initiate jawbone shrinkage or deterioration. In case you desire a dental implant but your jawbone isn’t strong enough to sustain the implant, you would have to undergo a bone graft. A bone graft is where bone tissues are extracted from a different part of the body and grafted to the jawbone. Once its volume increases, the implant surgery can be carried out.
