Non-Carious Tooth Surface Loss (NCTSL) is considered as a current issue of concern. It's management is challenging. Through this paper, the focus will be put on the different forms, locations and causes. Emphasis is placed on the importance of a thorough examination and indexing to assess the severity of tooth wear.A systematic and integrated approach leads to favorable and predictable prognosis. We aim to provide clear recommendations on the best treatment strategy and simplified guidelines to succeed tooth wear management? considering the patient's expectations, the esthetic demand as well as the risk profile.The patient should be fully informed. Restoration of severe tooth wear should ideally be delayed as long as possible.The different treatment modalities will be discussed according to the localization and the severity of tooth wear.The conservative, minimally invasive restoration, should first be considered.

After orthodontic treatment, smile optimization seems to be challenging mainly for patients who are highly demanding and seek perfect esthetics with minimally invasive approaches. Lithium disilicate have been proved to be very efficient to attain satisfactory esthetics with predictable and lasting outcomes. This article describes a detailed clinical protocol of successful lithium disilicate veneers after an orthodontic treatment to establish appropriate tooth position and a mucogingival surgery to correct gingival margins, thus improving the gummy smile.
