After a recent extraction, when does the extraction site typically disappear on an X-ray?

The extraction site typically shows significant healing and remodeling that can be observed on an X-ray approximately 18 months after a tooth extraction. During this time, the bone undergoes processes of resorption and remodeling, which can lead to changes in the appearance of the extraction site on radiographs.

In the initial months following extraction, there will be some loss of bone density and changes in the contours of the bone shown on X-ray. However, the more definitive changes that signal the completion of bone healing and regeneration in that area usually take up to 18 months. This period accounts for the stabilization and maturation of the bone following the surgical procedure.

While changes in the extraction site can still be visible at 6 months, and healing is certainly underway, it's not until around the 18-month mark that the area has typically reached a point where it might be less prominently visible or integrated into the surrounding bone. Viewing this from a clinical perspective, it reflects the ongoing biological processes at work and aids in understanding the timelines relevant for further dental work or assessments post-extraction.
