Explanation

We only get one set of grown-up teeth, so we must look after them. Brush your teeth twice a day, in the morning and before bed. Use a toothbrush and toothpaste with fluoride, which helps to make teeth strong. Sugar can make holes in teeth, so eat only a little of sweet food and sugary drinks. Food and drinks with calcium, such as milk and cheese, help to make teeth strong. Also visit the dentist to have your teeth checked. The dentist can help you keep your smile healthy.

Teeth chart (with an adult): make a table with a row for each day of the week and two columns, morning and bedtime. Every time you brush your teeth, draw a smiley face. At the end of the week, count your smiley faces. How many did you get? Can you get them all next week?
