Consistent tooth cleaning helps prevent decay, gum disease and avoidable dental pain.

**The number:** Brush for about 2 minutes each time ([NHS, 2025](https://www.nhs.uk/live-well/healthy-teeth-and-gums/how-to-keep-your-teeth-clean/))

## The evidence

- Evidence grade: A. Grade A: meta-analyses of randomised trials, or a major guideline consensus.
- Basis: NHS preventive oral care guidance and risk based dental recall recommendations
- Outcome: recommended toothbrushing duration
- Comparison: About 2 minutes each time, twice daily
- Impact: 72/100. The impact score is an editorial prioritization heuristic for the general list, not a validated estimate of your personal risk.

## Why it matters

Plaque builds up on teeth and around the gums, causing decay and inflammation. Fluoride toothpaste helps protect teeth, and cleaning between them reaches places a brush misses. NHS guidance recommends brushing twice daily for about 2 minutes and choosing dental recall intervals according to risk.

## How to do it

1. Brush every tooth surface for about 2 minutes twice daily, including before bed.
2. Use toothpaste with at least 1,350 ppm fluoride; spit out excess without rinsing immediately.
3. Clean between teeth daily with appropriately sized interdental brushes or floss.
4. Agree on your next dental checkup with your dentist; healthy adults do not all need six monthly visits.

## Talk to a clinician first

Persistent bleeding, toothache, swelling or a mouth change needs dental assessment. Ask for cleaning advice around implants, braces or gum disease.

## Putting it into practice

### Start now

- 1 minute: Check your toothpaste label: adults should use one with at least 1,350 ppm fluoride.
- 5 minutes: Brush every surface of all your teeth for about 2 minutes with fluoride toothpaste, then spit out the excess without rinsing.
- 15 minutes: Read the NHS cleaning guide and practise gentle cleaning between your teeth; ask a dentist about gaps you cannot clean comfortably.

### What it looks like

- Brush before bed and at one other time, using adult toothpaste with at least 1,350 ppm fluoride.
- After brushing, spit out the excess toothpaste and leave the fluoride on your teeth without rinsing.

### Common mistakes

- Mouthwash straight after brushing washes away fluoride, so use it at another time if you use it.
- A brush misses the gaps, so clean between teeth with floss or suitable interdental brushes.

### A structured start

**Build a complete daily clean**

1. Establish brushing before bed and at one other time each day.
2. Add daily cleaning between teeth with floss or brushes that fit comfortably.
3. Ask your dentist or hygienist to check your technique and agree your next dental review.
