Cuspal fractures are relatively common. Fortunately for esthetics, when a cuspal fracture occurs in a maxillary premolar, it most commonly involves the palatal cusp. Fractures with a favorable prognosis may be approached with a minimally invasive treatment to successfully retain the natural tooth. This report describes 3 cases of “cuspidization” to treat maxillary premolars with cuspal fractures. After identifying a palatal cusp fracture, the fractured segment was removed, resulting in a tooth that closely resembles a cuspid. Depending on the extent and location of the fracture, root canal treatment was indicated. Subsequently, conservative restorations sealed the access and covered exposed dentin. Full coverage restorations were neither required nor indicated. The resulting treatment provided practical and functional treatment with a good esthetic outcome. When indicated, the described cuspidization technique can conservatively manage patients with subgingival cuspal fractures. The procedure is minimally invasive and cost-effective and can be done conveniently in routine practice.
