External cervical resorption is a pathological process, with an etiology that is not completely understood. Possible predisposing factors are orthodontic treatment, trauma, internal whitening, bruxism, etc. Internal whitening is an effective and minimally invasive method for the whitening non-vital teeth. This method is associated with a risk of resorption, which if not treated, can lead to tooth loss. This case report describes the management of two upper incisors with external cervical resorption, with a previous history of root canal treatment and internal whitening.
