I've contacted a doctor in regards to buccal fat removal , he was very thermal about the procedure and I hnderstood everything , the only concern that I have is that he mentioned he would leave the incision open and free of any stitches so the incision can heal on its own within days . He said it was safe as long as I followed all hygiene instructions including using the special mouthwash he was going to give me . Is this ok ? Or should I be worried and look for another doctor ?
