The oral care aisle is crowded with promises, from “ultra whitening” to “6-in-1 protection”. In reality, only a few things decide how well your toothbrush and toothpaste protect you. This article cuts through the marketing so you can choose with confidence, and it fits into our wider guide to daily oral hygiene.

Choosing a toothbrush

Soft bristles

Choose soft or extra-soft bristles. Hard bristles do not clean better, and they can wear enamel and irritate gums. Most dental organisations recommend a soft-bristled brush for almost everyone.

A small head

A smaller head reaches your back teeth and awkward corners more easily. If you gag or struggle to reach the back of your mouth, try a compact head.

A comfortable handle

You should be able to grip the brush securely. Larger grips can help people with arthritis or limited hand strength, and children need brushes designed for small hands.

Manual or electric

Both clean well when used correctly. Electric brushes can make good technique easier, since they do the movement for you and many have timers and pressure alerts. They can be especially helpful for people with limited dexterity. If you use a manual brush well, you do not need to switch. For technique, see how to brush your teeth properly.

When to replace it

Replace a manual toothbrush or an electric brush head about every three months, or sooner if the bristles look frayed or bent. A worn brush cleans less effectively.

Choosing a toothpaste

Fluoride comes first

The most important ingredient is fluoride. It strengthens enamel and helps reverse the earliest stage of decay. Check the label to confirm that the toothpaste contains fluoride, and use it twice a day. Fluoride-free pastes are generally not recommended for protection against cavities unless your dentist advises otherwise for a specific reason.

Look for recognised approval

In some countries, dental associations award seals or marks to products that meet safety and effectiveness standards, such as the American Dental Association’s Seal of Acceptance. If your country has a similar scheme, it can help you narrow choices. If you are unsure, ask your dentist.

Match extras to your needs

  • Sensitive teeth: toothpastes for sensitivity can reduce discomfort over time if used regularly. If sensitivity is sudden or severe, see a dentist, since it can signal a problem.
  • Whitening toothpastes: these usually remove surface stains with mild abrasives or polishing agents. They do not change the natural colour of teeth. For stronger options, see our teeth whitening and cosmetic dentistry guide.
  • Gum care: some pastes include ingredients aimed at plaque and gum health. They do not replace good cleaning between teeth.
  • Children: use a child-appropriate fluoride toothpaste in the amount recommended for their age, as advised on the pack or by your dentist.

What you can safely ignore

  • Flavour and colour: pick what you like, because you will use it more.
  • Price: expensive products are not automatically better. A basic fluoride toothpaste can be just as protective.
  • Buzzwords: terms such as “natural”, “advanced” or “complete” are marketing, not guarantees. Read the ingredient list and look for fluoride.
  • Very abrasive formulas: if you brush hard or have sensitive or worn teeth, avoid pastes labelled as highly abrasive and ask your dentist for advice.

How much toothpaste to use

For adults, a pea-sized amount is enough. For children, follow the amount recommended for their age on the pack or by your dentist, and supervise brushing so they spit rather than swallow. After brushing, spit out the excess and avoid rinsing, so the fluoride keeps working.

Do you need mouthwash?

Mouthwash is optional. It does not replace brushing or cleaning between your teeth. If you use a fluoride mouthwash, use it at a different time from brushing so you do not rinse the toothpaste away. See our flossing guide for the other essential step.

If you are still unsure

If you have sensitive teeth, gum problems, braces, implants or a high risk of decay, your dentist or hygienist can recommend specific products. For a general question, you can contact us.
