Generally speaking, it takes about half a year for most people to fully recover after grinding the mandibular angle. Secondly, bone grinding surgery has certain surgical risks. If it is mandibular angle, it is usually within 24 hours after the critical period. There must be an observation period in the follow-up, so pay special attention. Don't laugh after grinding the bone for half a year, because the bone hasn't grown well yet! I didn't know this until I consulted Dr. Zhang Xiaotian. I suggest that if you want to do this kind of operation, you should still find a professional doctor.
