Following a tooth extraction, the jawbone begins to shrink. During the first year after an extraction, up to 60% of the width and up to 40% of the height of the bone can be lost. If the extraction site is left to heal on its own, the results can be unpredictable and often aesthetically displeasing. Extraction site preservation involves a very precise extraction to reduce damage to the bone structure, then a filling of the newly-exposed space with bone grafting materials in order to prevent any jawbone shrinkage even before it occurs.
Patients who opt for extraction site preservation almost always see more predictable and more cosmetically-appealing results. This treatment can be a key to a healthy and proper recovery from an oral extraction.
