Your face should not be swollen for more than 3-5 days at most after having a tooth pulled.

Salt water is a good rinse to keep infection away, use it heavy duty, and gargle too with it every few hours for about a week at least. I haven't ever had a problem with pulled teeth, 4 wisdom teeth pulled over 20 years ago, and two molars several months ago. It's doubtful any of them had the ligament scraped out proper either

Vitamin C helps you heal quicker.
