A frenotomy or frenectomy is a procedure that corrects a congenital condition in which the attachment for the tongue or upper lip is too tight, causing restrictions in movement that can cause significant difficulty with breastfeeding and in some instances, other health problems like dental decay or spacing, speech difficulties, and digestive issues. When it affects the lingual frenulum, this condition is commonly called a tongue-tie (the medical term is ankyloglossia). Approximately 20% of the population has this condition, so your lactation consultant or doctor may feel that a procedure is warranted to improve symptoms.
