Fun Teeth Facts

Read the tooth-care guide, then solve the challenges. Tick one answer unless a question says to tick all that apply.

Your teeth at work

Teeth help you bite and chew food. The front teeth are good for cutting and biting; the pointed teeth help tear; the flatter teeth at the back grind food. Most children grow 20 primary (baby) teeth. From about age six, these begin to fall out and are gradually replaced by permanent teeth. Many adults have up to 32 permanent teeth, including wisdom teeth.

1.A crunchy carrot is being chewed. Which teeth do most of the grinding?
  • The flatter teeth at the back
  • The front teeth
  • The pointed teeth
2.Complete the fact: Most children grow primary teeth.
3.Put these tooth changes in order, from earliest to latest: permanent teeth appear; primary teeth grow; primary teeth begin to fall out.

The clean-teeth mission

Plaque is a sticky layer of germs that can build up on teeth. Brushing carefully with fluoride toothpaste helps remove plaque and protect teeth. In the UK, children are generally advised to brush twice a day, including last thing at night, and to spit out toothpaste rather than rinse. Water is a tooth-friendly drink. Having sugary food and drinks less often helps protect teeth from decay.

4.Choose the best brushing plan for a day.
  • Brush once, only in the morning
  • Brush twice, including last thing at night
  • Brush only after eating sweets
5.Tick all the choices that help protect teeth: brushing with fluoride toothpaste; drinking water; having sugary drinks often; spitting out toothpaste after brushing.
  • Brushing with fluoride toothpaste
  • Drinking water
  • Having sugary drinks often
  • Spitting out toothpaste after brushing
6.Ellis brushes, then rinses her mouth with water straight away. What does the guide recommend she does instead, and why?
7.The sticky layer of germs that can build up on teeth is called .
8.A shark may replace lost teeth many times. Explain one way this is different from the usual pattern for people.
9.Imagine a friend says, “I can have sugary drinks all day if I brush once a week.” Use two facts from the guide to give them better advice.
