Security: The services that dental hygienists provide are needed and valued by a large percentage of the population. There is currently a great demand for dental hygienists. Employment opportunities will be excellent well into the future. Due to the success of preventive dentistry in reducing the incidence of oral disease, the expanding older population will retain their teeth longer, and will be even more aware of the importance of regular dental care. With the emphasis on preventive care, dentists will need to employ more dental hygienists than ever before to meet the increased demand for dental services.
