Invasive cervical resorption (ICR) is aggressive and expansionist variety of external tooth resorption that commences within the cervical region. The treatment goal must be complete elimination of all resorbing tissues and therefore the reassembling of the resorptive defect by the placement of an acceptable filling material to achieve desired function and esthetics. The restoration of the defect becomes demanding and strenuous if it extends coronally as well as radicular. This case presents the management of a Heithersay's Class 3 ICR in maxillary right central incisor using a surgical approach and restoration of defect with tri-layered combination of biodentine, resin-modified glass ionomer cement, and composite resin.
