The soft white object in the socket after tooth extraction may be healing tissue or food debris. The healing of the extraction wound is a complex process, first the blood clot is formed; then the blood clot hardens and granulation tissue is formed; then connective and fibrous tissues begin to replace the granulation tissue, at this time the inner surface of the alveolar socket is covered with yellowish-white soft material, which does not require any special treatment and is a normal phenomenon; finally, the fibrous bone tissue replaces the connective tissue, and it will take 3 months for the alveolar sockets to completely osseointegrate and heal. During the healing period, the alveolar socket is not completely flattened, which can lead to food debris remaining in it, which is usually white and soft, and is usually removed by rinsing the mouth with water. If there is any discomfort such as odor, bleeding, etc., it is recommended to consult a doctor promptly.
