Dental hygienists perform clinical tasks, serve as oral health educators in private dental offices, work in public health agencies, and promote good oral health by educating adults and children. Their main responsibility is to perform oral prophylaxis, a process of cleaning teeth by using sharp dental instruments, such as scalers and prophy angles. With these instruments, they remove stains and calcium deposits, polish teeth, and massage gums. There are approximately 192,330 dental hygienists employed in the United States.
