Hygienists are healthcare professionals who focus on promoting good health and preventing disease, particularly in the field of oral care. They often work alongside dentists to provide services such as teeth cleaning, patient education, and the application of preventive treatments. Their role is essential in maintaining oral hygiene and helping patients understand the importance of regular dental check-ups. In addition to dental hygienists, there are also hygienists in other fields, such as environmental hygiene, who ensure cleanliness and safety in public spaces. These professionals may conduct inspections, manage waste, and promote practices that reduce the spread of illness. Their work is vital for community health and well-being.
