The healing of the alveolar socket after tooth extraction is divided into several stages.

The alveolar socket will bleed after tooth extraction. The bleeding will stop after 15 to 30 minutes, and a blood clot will form to seal the wound, protect it, prevent infection, and promote normal wound healing.

The gums shrink a few hours after tooth extraction. After 24 hours, fibroblasts from the alveolar bone wall grow into the blood clot and fix the blood clot. The blood clot is replaced by granulation tissue in about seven days.

Three or four days after tooth extraction, more mature connective tissue begins to replace the granulation tissue, which is basically completed in about 20 days.

New strands begin to form 5 to 8 days after tooth extraction. About 38 days later, 2/3 of the extraction socket is filled with fibrous bone. It takes about three months to completely form bone. Mature bone cannot be replaced. Mature bone and alveolar apophysis function are reconstructed and restored.
