Marvellous Mouths

We have been learning all about oral health and how to look after our teeth. 

We shared our own experiences of going to the Dentist and used our role play area to re-enact these. In our 'Talk Through the Day' sessions we talked about what steps we need to take to brush our teeth properly as well as learning the meaning of some words. For our focus text, we looked at a non-fiction book that shared lots of interesting facts about why we need to brush our teeth, what happens to our teeth, why animals do not use toothbrushes and which animal has the most teeth.... do you know which animal has the most teeth? 

The best part of learning how to keep our teeth clean and healthy was the experiments that we carried out! Our first experiment was called 'Plaque Attack'. We did lots of talking around what lots of sugar can do to our teeth and what could happen if we didn't brush our teeth. First, we mixed sugar and water together and nothing happened but then we added plaque (yeast) to water and sugar and we were amazed at what happened!... the plaque grew and grew.

Our second experiment involved eggs, egg shells are like our teeth so we placed white egg shells in different liquids - tea, orange juice, water, fizzy pop, juice and vinegar and left them over night. We predicted that the egg shells would all be okay the next day. The next day came and we were amazed at what had happened! We used an egg that had not been in any liquid to compare the changes - The eggs in the fizzy pop, tea and juice were all stained from brown and even silver! The egg that was in the vinegar stained but had also gone really, really soft, the egg in the orange juice had a coating but the one left in the water was still the same. 

We then decided that to make the eggs right again, we needed to give them a brush with toothpaste and a toothbrush. We discussed that it is okay to have some sugar and treats in our diets but it is important that we brush our teeth twice a day and go to the Dentist at least once a year to make sure our teeth stay clean and healthy.
