According to its recovery law, it is advisable to avoid strenuous exercise within 1 week. Generally, the alveolar fossa is congested after tooth extraction, and a blood clot is formed in about 15 minutes. At the same time, the surrounding gum edge shrinks and rolls in, narrowing the wound. After 24 hours, the blood clot was organized, the wound was completely covered one week later, and new bone appeared on the sixth day. Four weeks later, new bone filled the alveolar fossa, and three months later, the new bone was completely formed. So 1 week suggests not to do strenuous exercise.
