Healthy teeth, happy smile

Brushing twice a day, eating fewer sugary snacks and visiting a dentist keep your teeth strong. Your grown-up teeth have to last your whole life.

Your teeth are changing

Around your age, milk teeth fall out and grown-up teeth come in. These new teeth have to last for the rest of your life.

Milk teeth matter too. They hold space for the new teeth and help you chew and speak.

How to brush

Brush twice a day, in the morning and before bed, for about two minutes each time.

Use a soft toothbrush and a small, pea-sized amount of fluoride toothpaste. Brush gently in small circles on the fronts, backs and chewing surfaces of every tooth.

Spit out the toothpaste afterwards. You do not need to rinse with lots of water, because a little toothpaste left behind keeps protecting your teeth.

Food and your teeth

Germs in your mouth love sugar. They turn it into acid that makes holes in teeth, called cavities.

Sweets, toffees, cold drinks and sticky snacks are best kept for special times, like festivals, and eaten with a meal rather than all day.

Water, milk, fruits, vegetables and crunchy foods are good for teeth. Rinse your mouth with water after eating sweets.

Visiting the dentist

A dentist can check your teeth, clean them and find small problems before they become big ones.

If a tooth hurts, your gums bleed often, or you hurt your mouth while playing, tell a grown-up so a dentist can take a look.

Key points

  • Brush twice a day for about two minutes.
  • Use a pea-sized amount of fluoride toothpaste and spit it out.
  • Keep sweets and cold drinks for special times.
  • See a dentist for check-ups and if a tooth hurts.

Myth or fact?

Myth

Milk teeth do not matter because they fall out anyway.

Fact

Milk teeth help you chew and talk, and they save space for grown-up teeth. Cavities in milk teeth can hurt and cause problems.

Myth

Brushing very hard cleans teeth better.

Fact

Hard brushing can hurt your gums. Gentle brushing with a soft brush works best.

Myth

Rubbing salt or charcoal on teeth keeps them white and strong.

Fact

Rough powders can scratch the outer layer of teeth. Fluoride toothpaste and a soft brush protect teeth best.

When to get help

  • Tell a grown-up if a tooth hurts, feels wobbly when it should not, or your gums bleed often.
  • If you knock out or break a tooth while playing, tell an adult straight away so you can see a dentist quickly.
