There are two types of frenectomy, labial and lingual. Both procedures carry risks and side effects. A labial frenectomy is done when the thin piece of skin that attaches the upper lip to the upper gum is strained and pulls the gums away from the teeth. A lingual frenectomy is done when the portion of muscle and skin that attaches the bottom of the tongue to the bottom palette of the mouth is connected too far out on the tongue, and interferes with talking, swallowing, or eating.
