A dental hygienist is a licensed healthcare professional who specializes in preventive oral care. They work alongside dentists to help maintain patients' oral health by performing tasks such as cleaning teeth, taking X-rays, and educating patients about proper dental hygiene practices. Their primary goal is to prevent dental issues like cavities and gum disease. In addition to cleaning teeth, dental hygienists assess patients' oral health and may apply fluoride treatments or sealants. They also provide valuable advice on nutrition and the best oral care products. Their role is essential in promoting overall health and ensuring that patients maintain good dental hygiene habits.
