Frenectomy can sometimes obstruct normal function, i.e. such as , limited movement of the tongue, which may affect speech during early development of the child and restricted smile of the upper lip, as well as in placement of dentures.
A Frenectomy is simply the “clipping” of the attachmen. There is release of the tissue and thus unrestricted movement of the upper lip with the labial frenum, and the tongue with the lingual frenum. The “clipping” of the side frenums, although rare, are done for allowing a better fit of dentures that may otherwise be dislodged or “fall out” easily.
