Dental hygienists perform cleanings (scaling) and teeth polishing. They assist the dentist or orthodontist during treatments and secure orthodontic attachments. They take dental radiographs, instruct patients on oral hygiene and infection prevention, and remove stitches and periodontal dressings. This is an essential job that requires cleanliness, discretion and method. A job as a dental hygienist is suited to neat, orderly people with good visual acuity and excellent dexterity.
