Dental hygienists provide support to practicing dentists by carrying out dental procedures such as oral examinations and preparing diagnostic tests. In addition they have a role in patient care, and many dental assistants also have administrative duties that may include billing, reception work, and stock management. Dental hygienists are generally licensed to carry out dental procedures such as removing tartar and other deposits from teeth. Some states also license dental hygienists to carry out minor surgery-related tasks such as administering anesthetic and removing sutures.
Most dental hygienists work in private practice as an assistant to a practicing dentist. However, some work in schools as dental nurses, and provide dental care to students, referring patients to dentists when necessary.
