Abstract
Objective: Approach through a narrative review on anatomy, diagnosis and treatment of ankyloglossia in early childhood to show the relevance of a dental intervention in those cases. Bibliographic Review: The mucous fold that runs from the lower half of the tongue to the floor of the mouth is called the tongue frenulum. The word "ankyloglossia" comes from the Greek words "agkilos" (curves) and "glossa" (tongue). It’s an anatomical condition in which the subject is born with a short frenulum, which may or may not impact the individual's life, as it limits movements that can result in changes in the speech. The relevance of a dental intervention for cases of ankyloglossia may favor a better performance of the tongue, without harming the functions of this structure. In the development of the treatment, the surgical procedure is fundamental with the objective of a better lingual flexibility allied to the speech therapy, aiming at the reestablishment of phonation and normal swallowing physiology. Final Considerations: When the problem is well marked, it can cooperate for the better progress of the individual's psychic-emotional, providing better mobility of the movement of the tongue, as well as a better pronunciation of the words.
