What Does a Dental Hygienist Do?

When you visit the dentist, you may spend most of your appointment with someone who’s not the dentist but is just as vital to your oral health. So, what does a dental hygienist do? At Beacon Hill Dental Centre in Burlington, Ontario, our dental hygienists are the compassionate experts who help you prevent cavities, maintain a healthy smile, and feel confident about your oral care.
Whether you’re due for a cleaning or exploring a dental career, understanding the dental hygienist’s role helps you feel more informed and comfortable at your next appointment.
What Is a Dental Hygienist?
A dental hygienist is a licensed oral health professional who works alongside a dentist to provide preventive dental care. Their main focus is on keeping your teeth and gums healthy through education, cleanings, and early detection of potential problems.
Common responsibilities include:
- Cleaning and polishing teeth to remove plaque, tartar, and stains
- Performing dental X-rays
- Examining your gums for signs of disease
- Applying fluoride and sealants to protect your teeth
- Educating patients on brushing, flossing, and healthy habits
- Charting dental conditions for the dentist to review
Dental hygienists help assess oral health issues early before they become painful or costly.
Dental Hygienist vs. Dentist
While both are essential to your care, dental hygienists and dentists have distinct roles:
Dental Hygienist | Dentist |
Focuses on prevention and hygiene | Diagnoses and treats oral conditions |
Performs cleanings and patient education | Performs procedures like fillings, crowns, and root canals |
At Beacon Hill Dental Centre, our team approach means your dental hygienist and dentist collaborate to give you complete, personalized care.
