This article describes how the Tooth Wear Evaluation System (TWES) can be used to diagnose existing tooth wear in a structured manner. Since its introduction, the TWES has been used by many dental clinicians in different countries. The collected feedback has been analyzed by the developers and users, resulting in an adapted version – the TWES 2.0. The adaptations and the newly introduced taxonomy have resulted in a smoother use in daily practice, a more straightforward diagnostic system, and a structured management.
