Flat Stanley has been very quiet lately. It seems that he has been eating lots of sweeties from Mrs Stewart’s cupboard and not looking after his teeth very well! He has had a bit of toothache.
Luckily one of our Superstars was able to take him to the dentist.
Stanley was a bit reluctant to open his mouth at first but eventually the Dentist was able to have a good look. He didn’t need any fillings this time but the Dentist had to scrape away some of the plaque and said that he will neeed to try much harder at brushing and flossing in the future.
Now that the Supertstars know all about teeth they will be able to give him some good advice about looking after his teeth properly.
Today we tried making our own toothpaste as part of our teeth topic. We used glycerine (to bind it together), bicarbonate of soda (fights off bacteria), salt (acts as an abrasive) and peppermint food colouring.
Mrs Stewart made a little tester but it was too salty. We reduced the amount of salt we used when we made our own and added more peppermint. We then tested it with our new toothbrushes. However, we all agreed it was MINGING (we have been talking about Scottish words this week!). We will be sticking to our usual toothpaste in future!
This term we will be concentrating on non-fiction writing. Today, we wrote our own instructions for brushing our teeth. We spoke about the importance of making sure our instructions are written in the right order.
In the afternoon we learned about the structure of a tooth. We learned that the outer layer is called enamel, the layer under that is called dentine and the middle is very soft and called pulp. We made our own paper models of the layers of the tooth and labelled them.
Here is a good website for learning about the structure of a tooth.
This term we will be learning all about teeth. Today we learned about some of the different types of teeth we have and the different jobs that they are designed to do. We looked at this website from the BBC.

We used our set of “big” teeth to look at incisors, canines and molars more closely.
