Toothwear may have a multifactorial aetiology but is often localized to the upper anterior teeth. This is normally accompanied by a loss of interocclusal space. This paper aims to outline the management of localized anterior toothwear. It discusses several options available to create space for anterior restoration, with particular reference to the use of the 'Dahl' technique. Dahl described a non-invasive technique to create increased interocclusal space. The increased space eliminates the need for further occlusal reduction during crown preparation which is ideal in the worn dentition. This paper illustrates and describes the clinical applications of Dahl's original technique.
