Dental microwear is the study of the microscopic scratches and pits that form on a tooth's surface as the result of its use. Much of the dental microwear research that has been conducted thus far has focused on humans and non-human primates. These can be used as models to reconstruct diets in human ancestors and other fossil primates.
