Tooth extraction is normally covered by medical insurance and can be reimbursed. So patients who have teeth that need to be extracted are advised to go to the oral and maxillofacial surgery department of a regular hospital for tooth extraction if their physical condition allows and their blood pressure is normal. After the extraction, you must follow the doctor’s advice, do not brush or rinse your teeth for 24 hours, and spit out the cotton ball bite for about half an hour to 40 minutes. After two hours, you can eat warm, cool, thin and soft food, and do not touch or suck the extraction sockets to prevent secondary bleeding. In addition, during the process of eating, attention should be paid to keep the extraction wound clean to prevent food residues from falling into the extraction wound and producing infection or dry socket, etc.
