Lesson details
Key learning points
- Humans have two sets of teeth in their lifetime; the teeth you have as a child are replaced by adult teeth.
- A build up of plaque can lead to tooth decay.
- To look after your teeth, visit the dentist for regular check-ups and brush twice a day with fluoride toothpaste.
- Food and drink that contains lots of sugar can cause tooth decay.
- Scientists investigate which drinks are harmful to teeth.
Common misconception
Pupils may believe that sweet food is bad for the teeth and savoury food is good for the teeth. Also, that drinks do not contain sugar and therefore cannot be harmful to teeth.
As you look at the effect of different drinks on teeth, children will be able to see that it depends on the sugar content of the drink. High levels of sugar cause damage to teeth.
