White bone visible in the tooth socket after tooth extraction

The white substance in the socket after tooth extraction is not bone. It is actually a blood clot, new granulation tissue, or a protective membrane that helps promote wound healing and accelerate coagulation. Do not poke it with hard objects, as this may interfere with the healing process. After tooth extraction, avoid touching the wound as much as possible—frequent contact will slow down recovery. If swelling or pain occurs, be sure to return to your dentist for a follow-up examination and treatment promptly.
