Teeth Investigation

Further to our learning about teeth this half term, we have been investigating which liquids do not harm our teeth.  So as a class we set up an investigation with four different liquids, these were milk, water, coke and vinegar.  The children then made a prediction about which ones would not harm our teeth.  As a class we then left it for 4 days and then checked which of the liquids had harmed the teeth.

Below are some photos of the children setting up the experiment and the results.

In literacy we have been looking at information texts and we have created our own ‘teeth’ information texts.

Below is an example of some of the writing that the children have done….

In this book there will be information about teeth.  It gives you their names, their place, how to look after them and much more about them.

The teeth names are incisors, canines, premolars and molars.  The molars are used for crushing and grinding and they are at the back of the mouth.  The premolars are also used for crushing and grinding and they are next to the molars.  The canines are used for stabbing and ripping and they are next to the premolars.  The incisors are used for cutting and snipping and they are at the front of the mouth.

You have two sets of teeth in your life they are called the milk teeth and permanent.

 The tooth is made up of the crown and the root.  Inside the tooth there are three parts. They are called enamel, dentine and pulp.  The enamel is the hardest part.  The dentine protects the pulp.  The pulp has the blood and nerves in it.

Don’t eat unhealthy foods because they can damage your teeth.  If food has sugar in it or is acidic it can mix with germs in your mouth.  This makes bacteria.  Bacteria causes small holes in your teeth called cavities.  To stop this you must brush you teeth two times a day.
