A frenectomy is a procedure that consists of releasing the frenum, a band of fibrous tissue, under the tongue or upper lip to allow for better range of motion. Children may be born with a combination of conditions called a tongue-tie (ankyloglossia) and/or a lip-tie causing restrictions in movement that can cause difficulty with breastfeeding, and in some instances, other problems like dental decay or spacing, speech and airway difficulties, and digestive issues.
