Why doesn't damaged bone around a tooth simply grow back? Gum disease can destroy tooth support, and healing does not automatically rebuild it. A bandage over a cut protects it while repair begins. In guided tissue regeneration, a membrane sits between the gum and damaged area. But it is not merely a cover. It selectively blocks faster-growing gum tissues from filling space first. That leaves protected space for cells from the periodontal ligament, the tissue linking tooth and bone, and nearby bone to repopulate the defect. Whether regeneration succeeds depends on defect, stability, infection control, and patient healing. Guided tissue regeneration does not create tissue or guarantee complete restoration; it improves conditions for the body's repair. So why doesn't it grow back? It often cannot rebuild predictably on its own. The procedure gives the right cells time and space to restore the support.
