A frenulum (also called frenum, lingual frenum, or lingual frenulum) is a band of tissue that connects the tongue to the floor of your mouth, and your lips to your gums. The tongue frenulum, for instance, is the small fold of tissue connecting the bottom of your tongue to the floor of your mouth.
In some cases, the frenum is too short, tight or tough, and basically does its job too well. The inhibited movement causes difficulty with regular tasks like eating and talking, or hurts proper development in children, leading to aesthetic problems. Most commonly, your child is lip tied or tongue tied.
A Lip Tie (labial tie) is the tissue that connects the upper lip to the upper gums. Sometimes this tissue is too thick, too tight, or both. The presence of a lip tie (upper lip tie) are mostly found in newborns and infants and are breastfeeding related.
A Tongue Tie is a condition when the frenulum connecting the tongue to the bottom of the mouth is too short, therefore restricting the range of motion of the tongue. The medical term for a tongue tie is Ankylglossia.
