A dental hygienist is a registered dental professional who cleans your teeth, removes hardened plaque (tartar) and shows you how to look after your gums at home. On the NHS in England, scaling is usually part of a Band 1 course of treatment when clinically needed. You can also book a hygienist privately, and in many cases you can see one without seeing a dentist first.
What a hygienist does
A scale and polish is the treatment most people think of. A hygienist removes plaque and hardened tartar from the teeth, then polishes them. The NHS describes scaling as a thorough clean of your teeth and gums.
Hygienists also give advice on brushing and cleaning between the teeth. The NHS recommends cleaning between your teeth every day with floss or interdental brushes. The NHS also notes that some treatment at a dental practice may be done by a hygienist or dental therapist rather than the dentist.
Who it is for
The NHS says that in the early stages of gum disease, your dentist may advise you to have your teeth cleaned by a hygienist. In more serious cases, deeper cleaning under the gums may be needed. A hygienist appointment can also suit anyone who wants a professional clean between check-ups or help with their cleaning routine.
Signs of gum disease the NHS lists include gums that bleed when you brush, floss or eat hard foods, and gums that become swollen, red and sore. If you notice these, book a check-up rather than waiting.
What happens at an appointment
- The hygienist checks your gums and asks about your cleaning habits and general health.
- They remove plaque and tartar, then polish the teeth.
- They show you how to brush and clean between your teeth, and may recommend products such as interdental brushes.
The NHS says you can ask to stop or take a break at any time during a dental appointment, and that you should tell the team if you feel anxious.
Seeing a hygienist without a dentist
Since 2013, the General Dental Council has allowed what it calls direct access. This means you can see a dental hygienist or dental therapist without seeing a dentist first. They can carry out their full scope of practice, except tooth whitening, and must refer you to a dentist if you need treatment outside their scope. Not every practice offers direct access, so ask when you book.
NHS or private
The NHS says scaling is usually included in Band 1, but extensive treatment, or treatment for complex gum problems, may be charged at Band 2. In England, from 1 April 2026, Band 1 costs £27.90 and Band 2 costs £76.60. The NHS provides scaling when it is clinically needed.
NHS dental treatment is free if you are under 18, under 19 and in full-time education, pregnant or have had a baby in the last 12 months, or receive certain benefits. Private hygienist appointments are widely available and prices vary by practice. See our costs guide and our guides to NHS dentists and private dentists.
How to choose a practice
- Check the hygienist on the General Dental Council register. Dental hygienists must be registered with the GDC to work in the UK.
- Ask whether the practice offers direct access hygiene appointments or whether you need to be a registered patient.
- Ask how long the appointment lasts and what is included.
Aftercare
A professional clean helps most when you keep up the routine at home. The NHS advice is to brush at least twice a day with fluoride toothpaste, spit after brushing rather than rinsing, clean between your teeth every day, and stop smoking if you smoke. The NHS suggests seeing a dentist if you have not had a check-up for 2 years, or 1 year if you are under 18.
