A dental hygienist primarily focuses on preventive dental care. Their role encompasses cleaning teeth, which includes removing plaque and tartar, and providing routine dental check-ups. They not only conduct cleanings but also educate patients on proper oral hygiene practices and the importance of maintaining good dental health, which includes dietary advice and techniques for brushing and flossing effectively.

This education component is crucial as it empowers patients to take charge of their oral health, potentially reducing the risk of cavities and gum disease. While some of the other options involve important aspects of dentistry, they fall outside the typical scope of practice for a dental hygienist. Dentists, for example, are responsible for performing surgeries, designing orthodontic treatments, and prescribing medications, which are not tasks handled by hygienists. Thus, the crucial combination of cleaning and patient education defines the primary role of a dental hygienist in the dental field.
