Dental hygienists are healthcare professionals who focus on preventing and treating oral diseases. They work closely with dentists to provide patients with cleanings, checkups, and education about proper oral hygiene. Their main goal is to help people maintain healthy teeth and gums, which is essential for overall health. In addition to cleaning teeth, dental hygienists also take X-rays, apply fluoride treatments, and teach patients about the importance of brushing and flossing. They play a vital role in identifying potential dental issues early, ensuring that patients receive the care they need to keep their smiles bright and healthy.
