Dental wear is a research area within the field of dentistry that focuses on the study of the processes and mechanisms that lead to the wearing down of teeth over time. This can be caused by a variety of factors, including normal aging, diet, tooth grinding, and other oral habits. Dental wear can have significant impacts on oral health, leading to issues such as tooth sensitivity, enamel erosion, and changes in bite alignment. Researchers in this area seek to understand the causes of dental wear and develop strategies for preventing and managing it effectively.
