Dental assistants help make dentists more efficient, and patients more comfortable. They perform a blend of direct patient care and administrative duties. Dental assistants prepare the dental exam room, sterilizing and setting up equipment. During appointments, dental assistants may take x-rays, hand dentists instruments, keep patients’ mouths dry, and teach patients about proper oral hygiene. On the administrative side, they maintain patient records, schedule appointments, and work with patients on billing and payment. Essential skills for dental assistants include detail orientation, finger dexterity, listening, and organization. Almost all dental assistants work in dentists’ offices. They wear safety glasses, surgical masks, and gloves, and follow safety procedures to protect themselves and patients. About one-third of dental assistants work part time. Some work evenings or weekends. Requirements to enter the field differ: some states require graduation from an accredited program, and licensure or certification. Other states have no formal educational requirements, and assistants learn their duties on-the-job.
