Invasive cervical resorption (ICR) is an uncommon condition involving the gradual loss of cervical tooth structure due to the invasion of fibrovascular tissue because of predisposing factors such as trauma, orthodontics, and intracoronal restorations. A 45-year-old female patient presented with a class III cervical lesion and a missing restoration on the maxillary left lateral incisor following trauma. Radiographic examination revealed a “moth-eaten” appearance and a negative pulp test when cold testing was performed. Since it was a Class III lesion, the Heithersay technique was the choice of treatment, which included the application of trichloroacetic acid (TCA 90%) as to induce coagulative necrosis. The lesion was then curetted, root canal treated, and restored with glass ionomer cement. One-year follow-up demonstrated satisfactory healing with no further resorption. The Heithersay approach proved to be successful in treating class III ICR lesions.
