The frenulum is a small fold of tissue, a small ligament that attaches a muscle to the gum tissue. The frenulum holds the tongue in place against the floor of the mouth and also holds the upper and lower lips in place against the gums. These are known as the lingual frenum and the labial frenum.

Some frenum tissue structures are larger than others, may be too big, or attached too close or not close enough. All of these abnormalities can cause problems with things like eating and talking.  For example, if a frenum is attached too close to the gum margin it can pull on the tissue causing or worsening a recession.

 A frenectomy is a simple procedure done to reduce the connection of the frenum in the mouth or in some cases remove it completely. 

 Patients who remove their frenulum, can have reduced pain or discomfort, and increased facial appearance. They can have improved self confidence in speech and stabilized prosthetics such as dentures. Furthermore, they reduce the chance for injury and prevent further recessions.
