Book excerpt: Tooth wear has implications for the aesthetics, function and longevity of the primary and secondary dentitions, while dentine hypersensitivity is a painful condition of the permanent dentition, which affects oral comfort and function. The consequences of tooth wear and sensitivity are potentially enormous, not least in financial terms to the profession, health services and patients. This comprehensive book is divided into three sections of tooth structure, tooth wear and dentine hypersensitivity. Tooth Wear and Sensitivity forms a basis from which to understand tooth wear and dentine hypersensitivity, whereby effective management protocols can be designed and more importantly, preventive strategies can be developed.
