Food residue in the extraction socket can be rinsed out or the residue can be removed. If there is food residue present inside the socket, you can wait for 24 hours and then gently rinse your mouth, which can dislodge the food residue, but it is best not to exert excessive force, so as not to cause the blood clot to fall off and affect the patient’s recovery. If the food residue is not completely removed, you can choose a regular hospital to ask a professional doctor to remove the residual material, so as not to cause inflammation of the socket or symptoms such as pain and swelling. You need to pay attention to your personal diet after the extraction of the socket, it is best not to eat stimulating food and avoid chewing on the affected side. Brush and rinse your mouth carefully after each meal to avoid food impaction, which may affect your recovery.
