A dental hygienist is a licensed dental professional who specializes in preventive oral health. Their main duties include cleaning teeth, examining patients for signs of oral diseases such as gingivitis, and providing other preventive dental care. They also educate patients on ways to improve and maintain good oral health. Dental hygienists typically work in dental offices and may also take X-rays, apply sealants, and administer fluoride treatments.

The role is essential in the dental field, focusing on patient education and prevention, which can significantly reduce the need for more extensive dental procedures. Being a dental hygienist requires completing an accredited dental hygiene program and obtaining licensure. The career can be rewarding, with opportunities for flexible hours, a comfortable work environment, and the ability to make a positive impact on patients' health.
