A Midline Maxillary Tusk-Shaped Incisor in an Infant

Abstract

A 4-month-old boy, who previously presented for a sizable gingival hemangioma on the lower gingiva two months earlier and was being treated with propranolol and monthly follow-up, now presented with a sudden onset of a white lesion in the upper gingiva that caused great discomfort during breastfeeding to his mother one morning. Examination of the oral cavity revealed in the midline of the upper gingiva, a primary dental eruption reminiscent of a tusk or a fang due to its incurved crown and sharp vertex (Figure 1A).
