A frenum is a naturally occurring muscle attachment whereby small strands or bands of muscle attached the lips, cheeks and tongue to bone near the teeth (either upper or lower). The properly positioned frenum plays little to no role in the function of muscles of facial expression or gingival (gum) health. A poorly positioned frenum, long or short frenum may have detrimental effect on:
A frenectomy is a release of the frenum from its bone base. The frenum is simply trimmed to satisfy the desired effect and sutures are usually not necessary.
Those undergoing orthodontic treatment need to be evaluated to see if the removal of an abnormal frenum can increase the stability and improve long-term success of the final orthodontic result.
