Dental hygienists play a crucial role in preventive care, which is essential for maintaining good oral health and preventing dental diseases. Their responsibilities primarily focus on educating patients about proper oral hygiene practices, conducting thorough dental cleanings to remove plaque and tartar buildup, and applying preventive treatments such as fluoride and sealants. This comprehensive approach helps to empower patients to take charge of their oral health and significantly reduces the risk of conditions like cavities and gum disease.

The emphasis on education is particularly important, as dental hygienists engage with patients to promote awareness of the relationship between oral health and overall health, providing insights on techniques for effective brushing and flossing, as well as dietary choices that can benefit teeth and gums.

In contrast, prescribing medications and performing surgeries fall outside the scope of practice for dental hygienists, as these tasks are typically reserved for licensed dentists. Assisting dentists during procedures is also not the primary focus of a dental hygienist's role in preventive care; their aim is to work proactively to prevent dental issues before they develop.
