Dental Hygienist Video Transcript

Dental hygienists provide dental care that promotes good oral health and helps prevent or repair problems with patient’s teeth. A typical day involves examining patient’s teeth and gums for cavities and disease, cleaning and polishing teeth, and teaching patient’s proper brushing and flossing techniques. Hygienists wear gloves, safety glasses, and surgical masks and follow strict safety procedures at all times. Most take X-rays of patient’s teeth. To be successful in this profession you must be detail-oriented and have the ability to work well with your hands. You can expect daily interaction with many different people from all walks of life.

While almost all dental hygienists work with dentist offices, about half work part-time. Since dentists often hire hygienists for a few days per week, some hygienists work for more than one dentist to reach full-time hours in the field. An associate’s degree in dental hygiene is required in this profession and usually takes three years to complete. All states also require dental hygienists to be licensed. In this career, you’ve got your patient’s back, or rather their teeth.
