Which toothpaste is best for most adults?
For most adults, the right toothpaste is one that contains fluoride at 1,350 to 1,500 ppm, used twice a day and spat out without rinsing. Beyond that, choose for a reason: a sensitivity toothpaste if teeth twinge with cold, a low-abrasion paste if you have exposed roots. Whitening and charcoal pastes only affect surface stain. At Creative Arts in Dubai, the dentist can recommend a paste for your decay risk.

Why is fluoride the ingredient that matters most?
Every time you eat or drink something sugary, bacteria in plaque turn the sugar into acid, and that acid draws minerals out of the enamel. Between those attacks, saliva puts minerals back. Fluoride tips that balance: it makes the enamel that is rebuilt more resistant to acid and helps repair very early weakening before it becomes a cavity. The WHO describes adequate fluoride exposure as an essential factor in preventing decay and encourages twice-daily brushing with a fluoride toothpaste of 1,000 to 1,500 ppm.
For adults, NHS guidance is a toothpaste with at least 1,350 ppm fluoride. The number is printed on the tube, usually in the small print as ppm F or as a percentage of sodium fluoride or sodium monofluorophosphate. If a paste does not list fluoride at all, it will not give that protection, however natural or premium it looks.
How you use it matters as much as which tube you buy. Brush for about two minutes, twice a day, with the last brush just before bed. Spit out the excess and do not rinse with water, because rinsing washes away the fluoride that keeps working after you finish. Our guide to how to brush your teeth properly covers technique.
What do the different types of toothpaste actually do?
Most toothpastes are a fluoride paste with one extra feature. This is what each feature does and who it suits.
| Type | What it does | Who it suits | What to know |
|---|---|---|---|
| Standard fluoride | Protects against decay | Almost every adult and older child | The baseline every other choice builds on |
| High-fluoride, on prescription | Stronger protection against decay | People at high risk: frequent new cavities, exposed roots, dry mouth, some orthodontic patients | Prescribed by a dentist for a specific person; not for children unless prescribed |
| Sensitivity | Calms nerve signals or blocks the tiny tubes in exposed dentine | Teeth that twinge with cold, sweet or air | Needs regular use for a few weeks; can be dabbed on sensitive spots |
| Gum or anti-plaque | Some contain ingredients that reduce plaque and gum inflammation a little | People prone to bleeding gums, alongside good cleaning | Will not treat gum disease that has formed pockets |
| Whitening | Removes surface stain with polishing particles or stain-lifting ingredients | Light stain from coffee, tea, karak or smoking | Does not change the natural colour of teeth or of crowns and veneers |
| Charcoal | Claims to whiten by absorbing stain | No group it is clearly recommended for | Claims are unproven, it can be abrasive and many contain no fluoride |
| Fluoride-free or herbal | Cleans and freshens | People choosing to avoid fluoride after discussing it with their dentist | Gives up the main protection against decay |
A paste for one purpose usually still contains fluoride. Check the fluoride figure whichever type you choose.
Which toothpaste helps sensitive teeth?
Sensitivity usually comes from exposed dentine, the layer under the enamel, which has tiny tubes running towards the nerve. It becomes exposed when gums recede, when enamel is worn by acid or hard brushing, or after whitening. Sensitivity toothpastes work in one of two ways: some calm the nerve's response, others block the tubes on the surface.
They help most when used every day for at least a few weeks; many people stop after a few days and conclude it does not work. Rubbing a small amount onto the sensitive area with a fingertip at night and not rinsing afterwards can help too.
A sensitivity toothpaste should not be used to cover up a problem. If a single tooth is sensitive, if the pain lingers after the cold has gone, or if it hurts when you bite, a dentist should look for decay, a crack or a leaking filling. Our page on sensitive teeth explains the causes and treatments, including fluoride varnish and bonding over exposed roots.
Do whitening and charcoal toothpastes work, and are they safe?
Whitening toothpastes remove surface stain, mostly through mild polishing particles and sometimes stain-lifting ingredients. They can make teeth look cleaner if you drink a lot of coffee, tea or karak, but they do not bleach the tooth, so they cannot change its natural colour. They also have no effect on crowns, veneers or fillings, which can make those stand out more as the natural teeth around them get cleaner.
Abrasion is the trade-off. A gritty paste used with hard scrubbing can wear exposed root surfaces, which are softer than enamel, and can dull the surface of composite bonding. If you have receding gums, sensitive teeth or bonding on your front teeth, a low-abrasion paste is the safer choice.
Charcoal toothpastes promise whitening and detoxing. A 2017 literature review in the Journal of the American Dental Association found insufficient clinical and laboratory data to support the safety and effectiveness claims made for them. Many contain no fluoride, and the particles can be abrasive. For a genuine change in shade, dentist-supervised whitening works on the colour inside the tooth; our guide to whitening product safety compares the options.
Not sure whether you need a standard, sensitivity or prescription-strength paste? At a check-up, the dentist assesses your decay risk and gums and tells you what to use, and how.
See preventive dentistryHow much toothpaste should children use, by age?
Amounts based on NHS guidance. Supervise brushing so children spit out and do not swallow or lick the paste.
| Age | Amount | Fluoride level |
|---|---|---|
| Under 3 years | A smear, about the size of a grain of rice | A family toothpaste of 1,350–1,500 ppm, or a children's paste of at least 1,000 ppm for children without decay |
| 3 to 6 years | A pea-sized amount | Family toothpaste suits children of all ages |
| 7 years and over | A pea-sized amount | Family toothpaste, as for adults |

What else on the label is worth checking?
A few other details can make a difference for some people:
- Sodium lauryl sulphate (SLS). A foaming agent in many toothpastes. If you get frequent mouth ulcers, NHS advice includes avoiding toothpaste that contains it; our page on mouth ulcers explains other triggers.
- Strong flavours. Intense mint or cinnamon can irritate a sensitive mouth. A milder flavour is fine as long as it has fluoride.
- Dry mouth. Some pastes are formulated to be gentler on a dry mouth. Fluoride matters even more here, because saliva is not protecting the teeth as it should; see our page on dry mouth.
- Braces and aligners. A fluoride paste is especially important around brackets, where plaque gathers and white marks can form.
Price and brand matter far less than these. A plain fluoride toothpaste used well twice a day protects better than an expensive specialist paste used carelessly.
Does toothpaste need a mouthwash or anything else with it?
Toothpaste cleans and protects the surfaces your brush reaches. Between the teeth, it needs floss, interdental brushes or a water flosser to do the cleaning; our guide to flossing and water flossers explains which to choose. A mouthwash is optional for most people; if you use one, use it at a different time from brushing so it does not wash the toothpaste's fluoride away, as explained in our mouthwash guide.
No toothpaste removes tartar once it has formed, and none treats established gum disease or a cavity. Regular check-ups and professional cleaning remain part of the routine, at the interval your dentist sets.
