How long until buccal fat removal swelling goes down?

Swelling is typical and can take several weeks to resolve. If you're concerned, I recommend following up with your surgeon. I hope this helps. 

Swelling post buccal fat removal depends on the patient's body healing ability. In 90 % of the patients the swelling last for 2 to 3 days. In 10% of the patients the swelling is severe and it could last up to 7 days.
