When a tooth is extracted, bone loss occurs rapidly. Up to 50% of the bone height and width will likely be lost within the first six months. Without intervention bone loss will continue. This makes it difficult or sometimes impossible to wear dentures, and can disqualify you as a candidate for implants. However, bone loss after an extraction can be prevented. If graft material is placed into the site soon after the tooth has been removed, little to no bone loss will occur.
