Help keep your kids’ teeth decay-free with these tips.
Children aged 3 -12 years
Tooth brushing
- Brush teeth before bed and once more each day. Use a pea-sized amount of fluoride toothpaste containing1450ppm flouride – check on the box. Use a small, medium-bristle toothbrush. Brush for two minutes with a manual or electric toothbrush.
- An adult should help until at least age 7.
- Spit out toothpaste, don’t rinse.
This leaves a protective layer of flouride on the teeth.
Diet and drinks
- Sugar can harm teeth. Save sugary food and drinks to mealtimes only.
- Best drinks: water or milk. Avoid brushing right after soft drinks or fruit.
- Best snacks: fruit, veg, or savoury foods.
- Save sweets and cake for mealtimes. Use stickers, not sweets, as rewards.
- Ask for sugar-free medicine.
Teenagers
- Brush twice a day – before bed and once more.
- Use a pea-sized amount of fluoride toothpaste (1450ppm).
- Use a small toothbrush with medium bristles.
- Don’t rinse – just spit.
- Ask your dentist about cleaning between teeth.
Diet and drinks
Too much sugar = tooth decay.
Best drinks: water or milk.
- Soft drinks and fruit are acidic – don’t brush straight after consuming them.
- Best snacks: fruit, veg, or savoury foods.
- Save sugary drinks, sweets, cakes and chocolates to mealtimes.
- Sugar has many names: honey, syrup, glucose – all harm teeth.
- Ask for sugar-free medicine.
- Drink through a straw to limit acid erosion on teeth.
People should have a dental check-up every 6 months, but some may not need to go so often and others may need more frequent checks. Dental care is free until the age of 18.
