Unfortunately, sometimes teeth fail and need to be removed (extracted). Chronic periodontal disease, deep decay that undermines the structural integrity of the tooth, and fracture are a few reasons that teeth require extraction. Other common reasons for dental extractions include removal of poorly positioned wisdom teeth, retained primary (baby) teeth, or to create space for orthodontic treatment. Many times patients will decide to replace a lost tooth with a dental implant. If a tooth is planned for extraction and the patient is considering replacing the lost tooth with a dental implant, placing grafting material in the tooth socket after the tooth is removed is generally a sound clinical decision. The rationale for grafting the extraction site is to help preserve the bone so there is as much bone available to receive and support the dental implant.
