A frenectomy is a surgical procedure that removes or loosens a band of tissue (frenum) that is connected to the lip, cheek or floor of the mouth. The frenum is a part of the normal oral anatomy but a large or wide frenum may inhibit normal function. When a frenum is too large or wide it can restrict the movement of the lip, cheek or tongue or may impinge on the gingiva (gums) and causes recession.
A thick frenum on the floor of the mouth may restrict the movement of the tongue, preventing speech or chewing function. A frenectomy may be indicated on children, depending on the extent of the restriction. Difficulty in speech may be an early indication of the problem.
A thick labial frenum is a band of muscles from the lip that may attach to the gingiva, contributing to a space between the teeth. This is often seen between the top or bottom front teeth. A frenectomy may be recommended to help stabilize the position of the teeth.
