Why do we get holes in our teeth?
  • Holes in our teeth are made from acid that eats away at tooth enamel.
  • All over our teeth is a thin layer called plaque that contains bacteria. When we eat the food in our mouth combines with the plaque to form acid.
  • The acid eats away at the hard outer layer of our teeth called the enamel. It makes the enamel soft and eventually a hole appears.
  • If the hole isnít fixed it can keep going through to the dentine (under the enamel) and eventually the pulp (the middle of the tooth). There are nerves in the dentine and the pulp and if theyíre exposed by the hole they can send pain signals to the brain (tooth ache).
  Did You Know?
  • Enamel is the hardest thing in your whole body, even harder than your bones.
  • When the Dentist gives you a filling, they drill away the soft decaying part of the tooth, and fill the hole that is left with something tough and resilient so the sensitive inside part of your tooth is once again protected.
  • Brushing your teeth helps prevent tooth decay and holes forming in your teeth.
Run your tongue over your teeth after you brush them in the morning. Do your teeth feel smooth and clean? Run your tongue over your teeth after lunch. Are they still as smooth and clean? Try it again just before you do your teeth before hoping into bed. How do they feel now? Are they getting the "furry" feeling? Thatís the build up of plaque on your teeth which is full of bacteria eating the left over food in your mouth and making acid!
When you do your teeth use dental floss and see how much gunk you can get out from between your teeth. Thatís plaque, bacteria and food scraps.
Did you hear about the tooth with a hole in it?
