After wisdom tooth extraction, it is better to eat spicy food after 1 week. After wisdom tooth extraction, blood clot is usually formed within 15-30 minutes, connective tissue gradually grows in after 1 day, gingival epithelium starts to grow to the surface of blood clot in 3-4 days, and the blood clot is basically replaced by granulation tissue in about 1 week, and the wound will initially heal. Moreover, the process of wisdom tooth extraction is generally more traumatic and the operation takes longer. If you eat spicy and stimulating food during this period, it may accelerate the local blood circulation, which may easily cause pain, swelling and delayed healing of the gum and extraction socket wounds, and may even induce dry socket syndrome and cause severe pain in the extraction socket. After tooth extraction, it is recommended to maintain good oral hygiene, avoid spicy and stimulating food, preferably eat light and nutritious food, try not to eat hotter or harder food, make sure to protect the blood clot, and do not sip or lick the extraction wound to reduce the infection of the wound.
