You can’t eat within 2 hours after tooth extraction, and you can eat properly after 2 hours. After tooth extraction, a gauze or cotton ball will be placed in the extraction socket, which needs to be bitten for about 30 minutes and then spit out. At this time, a clot will be formed in the extraction socket, which plays a very crucial role in the healing of the extraction socket, but at this time, it is not stable enough, and eating too early or too hot may lead to the dislodgement of the clot. After 2 hours after extraction, you can eat soft, warm and cool food, do not eat hard, overheated food, try to use the side without extraction to chew, to prevent clot dislodgement, causing the extraction socket to bleed again. Generally about ten days after the extraction socket is completely healed, you can eat normally. Do not brush your teeth or rinse your mouth for 24 hours after the extraction. If there is bleeding again or other discomfort after tooth extraction, you should go to the hospital in time and be treated under the guidance of the doctor.
