After wisdom teeth extraction, the bone (clinically known as alveolar bone) is exposed on the edges, which can be left to heal by resorption or undergo alveolar bone revision surgery. 1. There will be some exposure of alveolar bone at the edge of the wound after extraction; if the exposed alveolar tissue is small and there is no obvious pain symptom, it can be left to heal by resorption, and the alveolar bone can be restored to the normal level in two to three months in general. 2. If the alveolar bone in the extraction socket is exposed too much, accompanied by obvious occlusal pain and other symptoms for a long time without significant relief; we must consult a doctor for alveolar bone repair surgery, using professional tools (such as bone chisel, bone file, etc.) to repair the alveolar bone that is protruding or sharp can be smoothed. It is recommended to consult a doctor for a clear diagnosis of alveolar bone exposure after wisdom tooth extraction to avoid delaying the condition.
