Tooth extraction generally about a week can appear epithelial tissue healing, but to fully achieve bone healing generally need about three months.
After tooth extraction bite cotton ball 30 minutes spit out , at this time in the alveolar fossa, can form a blood clot to close the wound, blood clot has a hemostasis, to prevent infection, and promote the role of healing.
Around 24 hours the blood clot began to appear mechanization, fibroblasts like to the extension of the blood clot, 3 days or so can be bundled, become amorphous hoof tissue fibers.
Three to four days after tooth extraction , gingival epithelial blood clot surface growth, a week later visible epithelial healing is basically complete, but the extraction window wound is larger, the time may be delayed completion.
Six days after tooth extraction, new bone formation, four weeks or so new bone filled with alveolar fossa, the complete formation of tissue generally takes three months later.
Therefore, it usually takes one week to heal after tooth extraction, and three months for complete healing to be achieved.
