Did you know that sugar that is added to drinks joins with the bacteria in our mouths to form acid?
Many drinks also have acid added to them to stop them going off. Acid is a chemical that can dissolve things – we have it in our stomach to help us breakdown the food we eat. Our stomach should be very well lined though so that the acid doesn’t damage the stomach lining too. Imagine what acid can do to your teeth then if you drink it over and over again! This is one reason why it is so important to brush your teeth, because if the acid sits on your teeth it can start to cause holes and your dentist (and your mum!) will not be very impressed!
This is a great experiment that you can do at home to have a look and see what acid can do to your teeth. Here are the things that you will need:
1. Six different drinks:
- Sparkling water
- Tap water
- Tonic water
- Apple juice
- An energy drink
2. Six glasses
3. Six pieces of bone – you can either collect some bones from your dinner for example if you’ve had a roast meal you can use the carcass. Or you can go to your butcher and ask for a little piece of bone. You only need a very small piece but make sure each bit is roughly the same size – a slice of bone marrow cut into 6 pieces works well.
