Plaque and tartar: what they are and how they are removed

Most people have felt the fuzzy film on their teeth first thing in the morning. That film is plaque, and the hard, rough deposit it can turn into is tartar. This guide explains the difference, how a hygienist removes tartar and which daily habits help keep both under control, using NHS and charity sources.

What plaque is

The NHS website for England describes plaque as a bacterial film that builds up on the teeth and contributes to gum disease and tooth decay. Brushing with fluoride toothpaste prevents plaque accumulating.

The NHS advises brushing with fluoride toothpaste twice a day for about 2 minutes. Plaque forms continually, which is why the cleaning has to be repeated every day.

The NHS also says gum disease is caused by a build-up of plaque on the teeth. When plaque is not removed through regular brushing and cleaning, it builds up and irritates the gums. Gum disease is therefore the main reason dentists take plaque seriously.

Plaque vs tartar

Tartar is hardened plaque. The Oral Health Foundation says that if plaque is not removed by brushing, it can harden into calculus, which is another name for tartar. The words “tartar” and “dental calculus” describe the same thing.

The Oral Health Foundation adds that as calculus forms near the gum line, the plaque underneath releases harmful substances that irritate and inflame the gums. It says that if gum disease is not treated promptly, the bone supporting the teeth is destroyed.

The practical difference is who can remove it. The Oral Health Foundation says tartar can only be removed by the dental team, so a toothbrush at home will not shift it.

How a hygienist removes tartar

The treatment is called a scale and polish. The NHS website for England says a hygienist carefully removes the plaque and tartar that build up on the teeth. A hygienist is the member of the dental team who usually carries out this cleaning.

The NHS says that for established gum disease, a dentist may recommend professional cleaning by a hygienist. In more serious cases, treatment can escalate to deep cleaning under the gums, and possibly antibiotics and gum surgery. Which stage applies to you is decided by an examination, not by this guide.

In Northern Ireland, nidirect says Health Service dentists provide examinations, x-rays, scaling, polishing and gum treatments. It also says that before private treatment begins, your dentist will tell you what treatment you need and what the exact cost will be. Ask for the cost in writing if you are unsure, and ask whether the appointment will be with a dentist or a hygienist.

Tartar removal has no shortcut. Kits and tools sold for home use are not covered by the sources opened for this guide, so none is recommended here. If you can feel a rough ridge near the gum line, or your gums bleed when you brush, book an appointment instead of trying to remove it yourself. Speak to a dentist about what you are seeing.

Preventing build-up

The NHS website for England lists these daily habits:

• Brush with fluoride toothpaste twice a day for about 2 minutes.
• Clean between the teeth every day, with floss or interdental brushes.
• Avoid using mouthwash straight after brushing, because it can wash away the concentrated fluoride left on the teeth.
• Avoid wooden toothpicks, which risk damaging the gums.

The NHS says electric and manual toothbrushes are equally effective when used properly with fluoride toothpaste. For adults, it says toothpaste should contain at least 1,350 ppm fluoride, according to the NHS website for England, checked 6 October 2026.

On gum health, the NHS advises regular dental check-ups and hygienist appointments, more frequent visits if you are pregnant or have type 2 diabetes, and not smoking. The Oral Health Foundation says regular check-ups allow the dental team to remove build-up before serious damage occurs.

Children need a different amount of toothpaste. According to the NHS website for England, checked 6 October 2026, children aged 3 to 6 should use a pea-sized amount of fluoride toothpaste and children under 3 a smear. Children’s plaque control is covered by children’s dentistry teams, who can show you how to brush with them.

The NHS also says fluoride mouthwash helps prevent decay but should be used at a different time from brushing, such as after lunch. Interdental brushes suit the gaps between teeth, while floss reduces gum disease and decay by removing plaque along the gum line. The right size of brush varies, so ask the dental team to show you what fits your teeth.

Checks at home are limited. If you notice bleeding, swelling or a persistent bad taste, those are reasons to be seen, not to wait. This guide is general information and does not replace an examination.

Next step

If you think tartar has built up, book a cleaning and a gum check. To find a Belfast practice that lists hygienist appointments, start from the hygienist appointments hub. For checking a clinician before you book, the guide to the GDC register explains the steps. A listing shows what the practice says about itself, so confirm availability and fees with the practice.
