Labial frenectomy refers to removal of muscle fibers / tissue in the middle of upper lip which extents to the gum tissue between central incisors. These muscle fibers and the force they exert during function can cause the upper incisors to shift and separate (i.e. Diastema). Your orthdontist may request an oral surgeon to remove the labial frenum to help minimize such shift.
Lingual frenectomy refers to removal of muscle fibers / tissue the occurs in the floor of the mouth extending to or near the tip of the tongue on one side and to the gum tissue behind the lower central incisors in the other. This can limit range of tongue movement and compromise a child’s eating ability and phonetics. This is referred to as ankyloglossia or tongue tie. It can also cause recession of the gum tissue behind the lower incisors. Lingual frenectomy procedure allows removal of this band of muscle fibers and improve tongue movement.
Frenectomy is a relatively minor oral surgery procedure that often takes no more than 10-15 minutes to complete. It can be performed with local anesthesia, although IV sedation or nitrous oxide sedation are often given for more patient comfort.
