There will be swelling in different degrees during the recovery of the broken bone, but it will gradually subside in 3-7 days, and the suture can be removed in about a week. If you need to work at this time, you can go to work. But it takes about 1 month to completely reduce swelling. From 3 to 6 months, due to the changes of attachment position and muscle tension, the masseter muscle itself will rebuild itself and shrink, so the best effect is about 6 months.
