Summary

This study looks at tooth wear and tooth sensitivity in 2,500 adults across five U.S. locations. Researchers will use dental scans and questionnaires to find out how common these problems are and what factors—like diet or brushing habits—might cause them. Participants must be 18 or older, have at least 10 natural teeth, and attend a dental school appointment.
