The gubernaculum dentis (GD) is an anatomical feature described in literature as the eruption pathway that connects the dental follicle to the gingiva in permanent teeth. The gubernacular cord, which lies within the GD, serves as a link between the tooth follicle and the overlying gingiva and can be observed in the alveolar region on the lingual or palatal aspect of primary teeth. Cone beam computed tomography (CBCT) is regarded as one of the most effective and reliable imaging techniques for assessing the maxilla and mandible, including the teeth, due to its ability to capture high-resolution images of hard tissues. This report discusses a case involving a 16-year-old female who was referred for a CBCT scan regarding an impacted tooth 23, which revealed a hyperplastic dental follicle associated with the gubernacular cord. Many cases involving the GD likely go unrecognized or are incorrectly diagnosed. Therefore, noting such incidental findings on CBCT is crucial and should be given appropriate attention.
