A frenectomy is a surgical procedure that removes or loosens a band of muscle tissue that is connected to the lip, cheek or floor of the mouth.
The frenum is part of the normal oral anatomy, but may sometimes restrict movement of the lip, cheek or tongue. A labial frenum is a band of muscle from the lop that may attach to the gums, contributing to a space between the teeth.
The frenectomy may be recommended after orthodontic treatment to help stabilize the position of the teeth. Another indication for a frenectomy is a partial or full-denture patient whose function is hindered in chewing. Frenectomies are occasionally performed for aesthetic considerations if the frenum prevents a natural smile.
