The treatment of abnormal labial frenum is often a matter of dispute. The oral surgeon, rightly enthusiastic over his prowess in fashioning normal structures out of marred oral tissues, is apt to advise excision. The pediatrist, witnessing the remarkable mending of abnormal structure and function in the process of growth, is inclined to advise leaving the affected structure alone.
While dental texts reflect a lack of decisive thought on the subject, a questionnaire conducted by the International Journal of Orthodontia and Dentistry for Children1 reveals a growing skepticism among orthodontists regarding the advisability of excision. Leaders in this field are of the opinion that in most instances a thickened labial frenum will correct itself with the coming of the permanent canines and the second and third molars.
Confused parents often turn to the pediatrist to help decide what constitutes an abnormal frenum and how such abnormality should be corrected.
