Abstract
BackgroundThe lingual frenulum is a mucous membrane fold found underneath the tongue. It helps the tongue to perform its function. There are few anomalies that can affect the lingual frenulum, such as ankyloglossia and absence of the lingual frenulum. We report a case of two lingual frenula to educate practitioners about the presence of such an anomaly.Case presentationA 10-year-old healthy Saudi girl came to our dental clinic complaining of “malpositioned frontal teeth.” Upon intraoral examination, two lingual frenula were found connecting the tongue with the floor of the mouth. Intraoral examination revealed no other abnormalities.ConclusionDouble lingual frenulum is an existing frenulum anomaly that did not affect normal function of our patient. A search of the literature revealed that this may well be the first reported case of such a condition.

The lingual frenulum is a fold of mucous membrane found underneath the tongue
There are few anomalies that can affect the lingual frenulum and sometimes interfere with function, such as ankyloglossia, where the frenulum is attached near the tip of the tongue, commonly described as “tongue tie,” or absence of the lingual frenulum either sporadically or in some developmental conditions, such as Ehlers-Danlos syndrome [2, 3]
Summary
Double lingual frenula can be considered a variation from normal. In our patient’s case, it did not affect the tongue functions, so no intervention was needed. Further investigations of a larger population with double lingual frenula are needed to measure the correlation between double lingual frenula and difficulties in breastfeeding, speech impediments, malocclusion, maxillary constriction, and obstructive sleep apnea
