A small band of tissue
The lingual frenulum connects the underside of the tongue to the floor of the mouth. Tongue-tie, or ankyloglossia, describes a restriction of tongue movement related to this tissue. Frenulums vary naturally in length, thickness and attachment.
A visible frenulum is normal. Its appearance, or a heart-shaped tongue tip, cannot by itself show whether a child has a functional problem or needs treatment.
What an evaluation considers
A clinician looks at movement and the tasks that concern your family. For an infant, this may include observing a feed and reviewing growth. For an older child, specific oral tasks or speech concerns may guide assessment.
Many children with a noticeable frenulum have no problems. Monitoring or supportive care may be appropriate. A procedure should follow an individualized discussion of function, alternatives, risks and possible benefits.
