When a pocket forms around one or more teeth, it allows bacteria to invade the roots of the teeth, jeopardizing your smile. To reverse the condition, Dr. James Voorhees may recommend flap surgery in Lenexa, Kansas. Also known as osseous surgery, flap surgery involves cleaning the roots of the teeth and reshaping the bone and gums.
