Summary. Eruption of an inverted tooth is a rare condition. This case report describes the inverted eruption of a supplemental lower premolar in a 10‐year‐old Caucasian female. The tooth erupted in a downward direction and reached the lower cortical border of the mandible 2 years later. During an 8‐year follow‐up period, the tooth did not interfere with eruption of permanent teeth and the patient remained symptom‐free. Considering clinical examination, medical and dental history as well as scientific evidence, the inverted eruption was most likely caused by a developmental abnormality with an inverted location of the tooth bud. This reported eruption of an inverted tooth is extremely rare and requires a radiographic follow‐up to evaluate the relative position of this tooth in the jaw bone and its potential interference with neighbouring teeth or anatomic structures.
