It is normal for the blood clot to turn white after tooth extraction, don’t worry. 1. The blood clot in the extraction socket after tooth extraction will mechanize and grow new granulation tissue in about 24 hours. In about 7 days, the epithelial tissue will crawl along the surface of the blood clot, forming a white pseudomembrane, and the gums will initially heal. The white pseudomembrane attached to the epithelium and the whitening of the blood clot are normal phenomena and do not require special treatment. 2. If the blood clot disappears, only white pseudomembrane, and there is a special odor in the alveolar fossa, accompanied by severe pain, it may be the emergence of dry socket, need to consult a doctor in time. Therefore, it is normal for the blood clot to turn white after tooth extraction, and if there is pain or bad odor, you need to go to the dentist in time.
