👉 A hygienist is a healthcare professional who specializes in the prevention, diagnosis, and treatment of dental diseases and other oral health conditions. They use their knowledge and experience to provide guidance on how to maintain good oral hygiene, such as brushing teeth, flossing, and using mouthwashes or rinses. Hygienists also help patients with specific oral health concerns like cavities, gum disease, or tooth decay, and they can refer them to other healthcare providers if necessary.
