I'm a dentist, and I've had this kind of operation. Ten days is probably enough. Generally, it takes about 2 to 3 days to arrange the operation after admission, and the weekend is counted separately. After seven days of observation, it is basically stable and free from danger, and can be discharged. After simple mandibular surgery, the swelling will be fine, and it will completely disappear in two to three weeks. If you add the jawbone, it may take more than a month to recover.

I wish you a speedy recovery!
