This half-term in Year 4 we have been learning about teeth and the way sugar affects the enamel and the damage it can do if it is not brushed. We left eggs to soak in different liquids for a week and analysed the results. Sammy (a dental hygienist) also came in to explain how to brush our teeth properly as well as adding to our knowledge of hidden sugars in certain foods. After these few lessons, we are certainly going to be brushing our teeth twice a day!
