Complete recovery from buccal fat removal takes approximately three weeks. Your surgeon will give you a regimen to follow for a full recovery. The doctor will provide you with a special mouthwash that will help you stay infection-free. You'll also be given instructions on how to care for the incision. A liquid diet is necessary for the first couple of days. Your doctor will tell you how to transition to solid foods gradually.
