What Does a Dental Hygienist Do?
Dental hygienists clean teeth, examine patients for signs of oral diseases, and provide preventive dental care and education. They work closely with dentists to deliver comprehensive oral health services. Dental hygienists play a vital role in helping patients maintain healthy teeth and gums through routine cleanings and personalized care plans.
