The success of dental treatment is linked to planning, correct indication and professional skills. The objective of this study is to report a clinical case about the failure of ceramic veneers from teeth 14 to 24 and their periodontal consequences, which respectively presented over-contour, edema, gingival redness and bad smell, reported by the patient as the main complaint of gingival inflammation and bleeding spontaneous. The ideal treatment suggested was to remove all the pieces and make new laminates, however the patient requested another alternative, but to keep the pieces in her mouth, since she was afraid that endodontic treatment on the teeth in question was necessary, in addition to the aesthetics not being your main complaint. As a result, it was suggested to remove the overlapping of the facet by wearing the porcelain in open field surgery. Proceeding with the patient's consent, the surgery was performed and it was discovered that some pieces were invading the supracrestal distance. The distance recovery was achieved by means of osteotomy, after the pieces were regularized and finally sutured. Seven days after the surgery an improvement in gingival health was observed, however, the aesthetics were affected due to exposure of the cementation line, but the patient was satisfied with the result. This work confirmed the importance of the dental surgeon in having knowledge of the basic principles and mastery of the technique of ceramic laminates, as the lack of these factors can lead to the failure of the procedure.
