Dental hygienists use an assortment of different tools to complete their tasks. Hand and rotary instruments and ultrasonic devices are used to clean and polish teeth, including removing calculus, stains, and plaque. Hygienists use x-ray machines to take dental pictures, and sometimes develop the film. They may use models of teeth to explain oral hygiene, perform root planning as a periodontal therapy, or apply cavity-preventative agents such as fluorides and pit and fissure sealants. In some States, hygienists are allowed to administer anesthetics, while in others they administer local anesthetics using syringes. Some States also allow hygienists to place and carve filling materials, temporary fillings, and periodontal dressings; remove sutures; and smooth and polish metal restorations.

Dental hygienists also help patients develop and maintain good oral health. For example, they may explain the relationship between diet and oral health or inform patients how to select toothbrushes and show them how to brush and floss their teeth.
Hygienists sometimes make a diagnosis and other times may prepare clinical and laboratory diagnostic tests for the dentist to interpret. Hygienists sometimes work chair side with the dentist during treatment.
