Who is a Dental Hygienist?
A dental hygienist is a licensed oral health professional who focuses on preventing and treating oral diseases. They typically work alongside dentists in clinics, hospitals, and private practices. While dentists handle more complex procedures like fillings, root canals, or surgeries, dental hygienists are experts in routine care such as cleaning teeth, taking X-rays, and educating patients on proper oral hygiene practices.
Key Responsibilities of a Dental Hygienist
Dental hygienists perform a wide range of tasks that contribute directly to a patient’s oral and general health. Their main duties include:
1. Teeth Cleaning (Prophylaxis)
One of the most well-known roles of a dental hygienist is to remove plaque, tartar, and stains from teeth. This cleaning helps prevent gum disease and tooth decay.
2. Oral Examinations
Dental hygienists often conduct preliminary oral exams to check for signs of gum disease, tooth decay, or oral cancer before the dentist arrives.
3. Taking X-rays
They are trained to take and interpret dental X-rays, which help in diagnosing hidden problems below the gum line or between teeth.
4. Patient Education
Educating patients on the importance of oral hygiene, brushing techniques, flossing, and healthy eating habits is a major part of a hygienist’s job.
5. Applying Preventive Treatments
Dental hygienists may apply fluoride, sealants, or other treatments to strengthen enamel and prevent cavities.

Earn an associate degree in dental hygiene from an accredited institution (usually a 2–3 year program).
