We are often asked when you should brush your teeth, and in particular whether it should be before or after breakfast. The honest answer is that it depends on what you eat and drink, but a few simple rules make it easy to get right.

Brush twice a day, including last thing at night

The NHS advises brushing for about two minutes, twice a day, with a fluoride toothpaste. One of those times should be last thing at night, before bed. Saliva flow drops while you sleep, so going to bed with clean teeth and a coating of fluoride gives them the best protection overnight.

Before or after breakfast?

Plaque and bacteria build up overnight. Brushing before breakfast removes them and leaves a layer of fluoride on your teeth before you eat. For many people this is the simplest morning routine. After breakfast, rinse your mouth with water.

If you prefer to brush after breakfast, that is fine too, but think about what you have eaten and drunk.

Wait after acidic food and drink

Acidic food and drink, such as fruit juice, citrus fruit and fizzy drinks, softens the surface of the enamel for a while. Brushing straight away can wear that softened enamel. If you have had something acidic, wait about an hour before brushing.

Spit, don't rinse

After brushing, spit out the toothpaste but do not rinse your mouth with water. Rinsing washes away the fluoride that helps protect your teeth. If you use a mouthwash, use it at a different time of day from brushing, for example after lunch.

Our top toothbrushing tips

• Brush for about two minutes, twice a day, including last thing at night.
• Use a fluoride toothpaste. Your dentist can advise on the right strength for you or your children.
• Brush every surface of every tooth, and along the gum line.
• Clean between your teeth every day with floss or interdental brushes.
• Replace your toothbrush, or electric brush head, every three months or sooner if the bristles are worn.
• Keep sugary food and drink to mealtimes rather than snacking through the day.

Building good habits

A regular routine matters more than the exact time of day, especially for young children. Help children brush until they can do it well themselves, and supervise them so they spit out the toothpaste. Good habits learnt early tend to last.

Frequently asked questions

Should I brush after lunch too?

Twice a day is enough for most people. After lunch, rinsing with water or chewing sugar-free gum can help.

Is it bad to brush straight after orange juice?

Yes, it is better to wait about an hour after acidic food and drink before brushing.
