Oral Hygiene Essentials

Read each question carefully. Use the information on this page to solve the tasks. For written answers, explain your thinking where you can.

Tooth-care detective

Good oral care helps protect teeth and gums. Plaque is a sticky film containing bacteria. When bacteria use sugars from food and drinks, they produce acids that can damage tooth enamel over time.

1.Choose the best everyday brushing routine for most children:
  • Brush once a day for 30 seconds.
  • Brush twice a day for about two minutes with fluoride toothpaste.
  • Brush after every sip of water.
  • Brush only when food is stuck between teeth.
2.Name two things used in an effective brushing routine and explain what each one is for. For example, think about a toothbrush, fluoride toothpaste, and brushing for about two minutes.
3.True or false? Plaque is a sticky film that can build up on teeth.
TrueFalse
4.A plaque bacterium uses sugar from a sweet drink. What can it produce that harms tooth enamel?
  • Acid
  • Oxygen
  • Fluoride
  • Water
5.After brushing with fluoride toothpaste, what is generally recommended?
  • Spit out the toothpaste and avoid rinsing straight away.
  • Swallow the toothpaste.
  • Rinse repeatedly with a large cup of water.
  • Eat a lolly to remove the taste.

Make healthy choices

Small choices throughout the day can affect teeth. Water is a good drink between meals. Frequent sugary snacks and drinks give plaque bacteria more chances to make acid. Fluoride helps make tooth enamel more resistant to acid.

6.Dylan has a choice of water or a soft drink to have between meals. Which is the better choice for her teeth, and why?
7.Complete the idea using the information in the section above: Fluoride helps protect teeth by making the enamel more to acid.
8.Match each habit to its main benefit.
  • Brush twice a day with fluoride toothpaste
  • Choose water between meals
  • Visit a dental professional for check-ups
  • Avoids frequent sugary drinks
  • Helps remove plaque and protect enamel
  • Helps check teeth and gums and give personal care advice
9.Matilda says, “If my teeth do not hurt, I never need a dental check-up.” Explain why Matilda should still follow the check-up advice given by a dental professional.

Share the message

Use what you have learned to help someone else make a healthy choice.

10.Write a short, catchy reminder for a younger child that includes one useful tooth-care habit and why it matters.
Draw a small poster to go with your reminder. Include a toothbrush, a healthy choice, or another helpful oral-care symbol.
