You can drink milk after tooth extraction, but you should pay attention to the fact that you should drink milk only after two hours of tooth extraction and there is no obvious bleeding from the wound. Also pay attention to the temperature of the milk, do not drink milk that is too hot, otherwise it may irritate the wound and make it bleed, which is not conducive to the healing of the wound. The diet after tooth extraction should be mainly warm and cool liquid or semi-liquid food, such as rice porridge, soup, noodles, etc. Do not eat too hot, too hard or spicy stimulating food, which may damage the blood clot and be detrimental to the wound healing. It is also important not to brush teeth, rinse mouth or take hot bath for 24 hours after tooth extraction, and not to lick the wound with tongue to avoid affecting the wound. Patients should also pay attention to keep sufficient rest and avoid staying up late and overworking, which are not conducive to wound healing.
