Swimming is recommended after one week following the extraction of a large tooth. Large teeth, especially the last wisdom tooth, are deeper after extraction, so do not engage in strenuous exercise, including swimming, for a week. Strenuous exercise can cause accelerated blood circulation and increased blood pressure, which can trigger the dislodging of blood clots in the extraction sockets. Swimming may cause the blood clot in the extraction socket to dislodge, resulting in bleeding from the extraction wound and prolonging the healing time. Bacteria in the pool may also cause infection of the extraction socket or dry socket. It is recommended to wait until the soft tissues in the extraction socket are completely healed and the extraction wound is completely covered after a week before swimming. Therefore, it is important to wait at least a week to swim after an extraction to avoid bleeding or infection of the extraction wound.
