A frenum is a naturally occurring muscle attachment, normally seen between the front teeth (either upper or lower). It connects the inner aspect of the lip with the gum. A frenectomy is the removal of a small fold of tissue that attaches to the gum tissue and the lip, or the tongue. The procedure is done predominantly for orthodontic purposes. There is minimal post-operative pain when the procedure is performed with a laser. When indicated, a gingival graft is done in conjunction with the frenectomy to increase attached gingiva and decrease recession.
