The dental hygienist is one of the most important members of the dental team — yet many patients are unclear about their role and how it differs from a dentist. Here is everything you need to know.
Who is a dental hygienist?
A dental hygienist is a qualified, GDC-registered oral health professional who specialises in preventing and treating gum disease, providing professional cleaning, and educating patients about maintaining excellent oral health at home.
At Park Royal Dental Clinic, Sara Moshtofar is our Principal Dental Therapist and Hygienist. She holds a dual qualification from Barts and The London School of Medicine and Dentistry (Queen Mary University of London) and has worked across private practice, hospital settings, and community dental services.
What does a dental hygienist actually do?
Professional cleaning (scale and polish)
The hygienist removes calculus (hardened plaque) that cannot be removed by brushing at home. This build-up, if left, causes gum inflammation, gum disease, and eventually tooth loss.
Gum disease treatment
For patients with gum disease, the hygienist carries out deeper cleaning below the gumline — called root surface debridement or deep cleaning. This removes bacteria and allows the gums to reattach to the teeth.
Airflow treatment
Sara uses EMS Airflow technology — a high-pressure jet of warm water, air and powder — to remove biofilm and staining more effectively and comfortably than traditional cleaning.
Personalised home care advice
Every patient gets tailored advice — the right toothbrush, the right interdental tools, the right technique for their specific situation. This is arguably the most valuable part of the appointment.
Hygienist vs dentist — what's the difference?
A dentist diagnoses and treats dental problems — decay, fractures, root canals, crowns. A hygienist focuses specifically on gum health and prevention. Both roles are essential, and they work closely together to keep your mouth healthy.
How often should I see the hygienist?
For most healthy patients, every six months. If you have a history of gum disease, every three to four months. Sara will recommend the ideal interval for your situation.
