[Restoration of pathological tooth wear]

On account of tooth wear, a 30-year-old man and a 23-year-old woman were referred to a clinic for specialised dental services by their general dentist. The man suffered from degradation of hard dental tissues. He was not in pain but had some functional problems. In addition, the diminishing aesthetics bothered him. The woman suffered from pain frequently, had mild functional complaints and a deep bite. Treatment of pathological tooth wear begins with a sound diagnosis and investigating and eliminating aetiological factors. Sufficient motivation on the patient's side is also important. The treatment should be as minimally invasive as possible. When indirect restorations are absent a dynamic treatment plan would be preferred, in which new spatial relations can be tested in composites. For the treatment of localised loss of dental tissue the Dahl Concept might be considered. Both cases emphasise the importance of evaluating the implemented treatment. Long-term follow-up is necessary for the enhancement of knowledge and experience in the interpretation of the aetiology of and approach to severe tooth wear.
