Do your kids resist brushing their teeth? After this tooth decay experiment with eggshells, they might run to clean their teeth after a meal!

In this tooth decay experiment, we will explore what stains tooth enamel and what breaks them down. Did you know that enamel is the hardest substance created by the human body? Yup, tooth enamel, which covers our teeth and protects them, is even stronger than bone. So once then enamel is damaged, it’s not possible to 100% restore it. This eggshell decay activity is excellent to show your kids what happens to their teeth if they keep eating or drinking...
