Abstract
Background The 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 presentation A 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. Conclusion Double 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.
