In the oral cavity, most people have two bands of tissue called frenums that are located in and around the teeth and gums. They are two basic types of frenums: a lingual and a labial frenum. The lingual frenum is located between the base of the tongue and the floor of the mouth. If the frenum restricts the movement of the tongue, a surgical procedure called a frenectomy may be performed.
In the upper arch, the tissue that connects the gum to the lip is called the labial frenum. If it is abnormally wide or long, it can create a space between the two front teeth, and that may require a surgical procedure.
Frenectomies are a very common laser procedure that can be accomplished effectively with any wavelength. Simple ones can often be achieved with topical anesthesia only. Hemostasis is usually excellent, particularly with the more thermal CO2, Nd: YAG, and diodes.
