What does “Alveolar bone resorption” mean?
Alveolar bone resorption is a reduction in the amount or height of jawbone surrounding teeth. Causes and situations must be distinguished, including loss due to periodontitis and bone changes during healing after extraction.
Original spelling: 잇몸뼈
How it differs from gum recession
Alveolar bone supports teeth beneath the gums. Visible gum recession and bone loss may be related but are not the same change. Periodontal examination and radiographs assess remaining support; a single image does not establish the current rate of progression.
Areas with teeth and areas without teeth
Around teeth, inflammation and attachment loss from periodontitis are assessed together. At extraction sites, the ridge width and height may change through healing and remodeling. The cause affects decisions about periodontal treatment, observation, or preparation for prostheses and implants.
Treatment goals and limits of recovery
Controlling inflammation to reduce further loss and reconstructing bone already lost are separate goals. Regeneration or bone grafting may be considered for some defects, but not every area of loss returns to its original state. Remaining bone shape, whether the tooth can be preserved, and the planned prosthesis position are considered together.
Frequently Asked Questions
Does scaling make lost bone grow back?
Scaling and periodontal treatment are important for inflammation control but do not restore all lost bone. A separate assessment is needed to determine whether regeneration can be attempted in the defect.
Does bone loss on an X-ray mean immediate extraction?
Bone quantity alone does not determine the decision. Remaining support, mobility, infection, restorability, and maintenance conditions are assessed together.

What caused the bone change, and is it currently progressing?
Explanation and evidencePeriodontal examination and comparison with earlier images distinguish past loss from current inflammation.
