Frenectomy

We have naturally occurring muscle attachments in our mouths, which connect our upper and lower jaws to the muscles of speech and eating. These muscle attachments are located on both the outer and inner aspect of our jaws.

A prominent lingual muscle attachment, or frenum, can occur between the under-surface of the tongue and the inner aspect of the gum of the lower front teeth. This condition is commonly known as a “tongue-tie” (Figure 1). It will significantly restrict movement of the tongue and can affect speech. It can even make basic home oral hygiene techniques such as brushing and flossing more challenging. A frenectomy may be indicated in order to eliminate this prominent frenum. Tongue posture, tongue mobility, oral functions, and communication are all dramatically improved following this procedure, as the tongue is immediately allowed a wider range of motion (Figure 2).

A prominent labial muscle attachment, or frenum can occur between the gum of the upper or lower front teeth, on the facial aspect – and the inner aspect of the lip (Figure 3). It has the potential to exaggerate muscle pull on the gum, resulting in gum recession. This frenum may also prevent the teeth from coming together, resulting in a gap (diastema). A frenectomy may be indicated in order to help release this muscle attachment from the gum (Figure 4). When orthodontic treatment is planned, the removal of a prominent frenum may increase the stability and improve the success of the final orthodontic outcome.

This is a short procedure. Patients usually resume most of their normal eating and oral hygiene practices within 1-2 days (see “Post-Operative Instructions”). The majority of healing takes place during the first week.
