Aim To present a case of a pulpless permanent incisor that continued root formation following root canal treatment. Summary A healthy 8‐year‐old girl with a history of dental trauma resulting in a coronal fracture involving enamel, dentine and pulp was referred by her general dental practitioner for treatment and evaluation of tooth 21. The tooth had a necrotic pulp and periapical rarefaction was evident radiographically. The canal was prepared, dressed with Ca(OH) 2 and then filled with a rolled gutta percha cone and Roth's root canal sealer. A radiograph exposed eight years post‐treatment, showed evidence of continued apical formation. Key learning points• Teeth with necrotic pulps and periapical rarefaction may show evidence of continued apical formation after root canal treatment. • Hertwig's epithelial root sheath may be more resistant than expected to trauma and infection.
