How to get rid of buccal fat removal remaining suture? Is it normal 3 weeks post op?

Thank you for your question. I recommend you make an appointment to see a plastic surgeon so they may evaluate your complaint. I imagine they will be able to easily removed the offending suture. Best of luck. 

Resolvable sutures from buccal fat removal usually dissolve in 2 weeks after surgery. In some cases, the sutures could remain for longer (up to 3 , 4 and even 5 weeks).If a buccal fat removal suture is still present inside the mouth after two weeks, the safest way to revue is by going back to the surgeon that performed the prodecure and get it removed by either the surgeon or his/her qualified staff.
