A frenum is a naturally occurring muscle attachment, normally seen between the front teeth (either upper or lower) but also noted between some premolar teeth on the sides of the mouth. The frenum connects the inner aspect of the lip with the gum. A lack of attached gingiva (the firm gum around the teeth), in conjunction with a high (closer to the biting surface) frenum attachment, which exaggerates the pull on the gum margin, can result in recession. Additionally, an excessively large frenum can prevent the teeth from coming together resulting in a gap between the front teeth. If pulling is seen or the frenum is too large to allow the teeth to come together, the frenum may be surgically released from the gum with a frenectomy. A frenectomy is simply the surgical removal of a frenum.
When Orthodontic treatment is planned or initiated, the removal of an abnormal frenum, with or without a gingival graft, can increase stability and improve success of the final orthodontic result.
Note: Any surgical or invasive procedure carries risks. Before proceeding, you should seek advice from an appropriately qualified health practitioner
