| The moisture called saliva in your mouth contains special chemicals that work on the starchy food you eat. |
 |
| The starch is turned into sugar. | |
| This sugar and the sugar in your food and drink leave a gluey paste on your teeth. |

|
|
This provides a great place for harmful bacteria to breed. If you do not brush your teeth these bacteria start to make acids which go on eating at the hard outer layers of your teeth until they bore right through to the soft inside. |
 |
