When an adult tooth is removed and not replaced, jawbone deterioration may occur. Natural teeth are embedded in the jawbone, and stimulate the jawbone through activities such as chewing and biting. When teeth are missing, the alveolar bone, or the portion of the jawbone that anchors the teeth in the mouth, no longer receives the necessary stimulation, and begins to break down, or resorb. The body no longer uses or “needs” the jawbone, so it deteriorates and goes away.
The rate the bone deteriorates, as well as the amount of bone loss that occurs, varies greatly among individuals. However, most lost occurs within the first eighteen months following the extraction, and continues throughout life.
X-ray A and B shows bone loss around extracted tooth. With SAC treatment for 10 months, 60-year-old male shows rapid building up of jaw bone even where a tooth is extracted.
