Double Tooth in a Dog: A Case Report and Treatment of a Developmental Tooth Disorder

Tooth structure anomalies, though not frequently described, can be observed in the external appearance not only of humans but also of dogs. The emergence of an oversized set of teeth is not solely an esthetic and health problem, but often also leads to behavioral issues. In the commonly available medical literature, there are many cases describing the occurrence and treatment of double teeth, both in the incisors and in the cheek teeth. In this article, the authors describe a clinical case of a one-year-old female Golden Retriever dog diagnosed with a double tooth in her permanent dentition. The complex morphology of the affected tooth posed a considerable diagnostic and therapeutic challenge. Surgical separation of the tooth was performed, requiring an individualized treatment approach and the adaptation of protocols derived primarily from human dentistry. This case highlights the diagnostic and clinical decision-making difficulties associated with such anomalies. It also emphasizes the importance of tailored therapeutic strategies for managing rare dental developmental abnormalities in dogs. The teeth were successfully surgically separated, and thus the present report contributes to the limited body of literature on double teeth in veterinary patients and provides practical insight into their management. This description of the first case of this type in veterinary dentistry aims to encourage readers to explore the topic of double teeth and demonstrates a non-standard way of thinking and dealing with such a tooth. The presented case is unique from both a diagnostic and therapeutic perspective. Previous publications have focused on these abnormalities as separate entities, failing to consider their simultaneous occurrence within a single tooth. The therapeutic approach employed also deserves particular attention. The most commonly recommended approach involves extraction of the affected teeth; however, in this case, an attempt was made to separate and preserve them, representing a novel clinical approach.
