A rare case of ankyloglossia and bilateral fusion of mandibular incisors.

Dental anomalies may occur both in primary and permanent dentitions. Abnormalities in tooth size, shape, and structure result from disturbances during the morphodifferentiation stage of development. They are observed frequently during routine dental examinations and might be associated with a syndrome. Dentists must be familiar with the prevalence of such anomalies, as early diagnosis can prevent complications such as compromised aesthetics, space loss, midline shift, and carious exposure. This article describes a rare presentation of bilaterally fused permanent mandibular central and lateral incisors, along with ankyloglossia and fluorosis in a 22-year-old man with the chief complaint of "dirty teeth."
