This experiment simulates the protection power of Fluoride.

What you'll need:
1 bottle of Fluoride rinse solution (available from your dentist, local dental supply company and some pharmacies)
2 eggs
1 bottle of white vinegar
3 containers

What to do:
Pour four inches of Fluoride rinse solution into one of the containers and then place an egg in the solution. Let it sit for five minutes. Remove the egg. Pour four inches of vinegar into each of the remaining two containers. Put the egg that has been treated with the Fluoride into one container of vinegar and the untreated egg in the other container of vinegar.

What will happen:
One egg will start to bubble as the vinegar (an acid) starts to attack the minerals in the egg shell. Which egg do you think will start to bubble?

This experiment simulates an acid attack on bones (bones are rich with calcium, just like your teeth).

What you'll need:
2 clean chicken bones (ask your parents to save them for you the next time you have chicken for dinner)
1 container
1 bottle of white vinegar

What to do:
Pour several inches of vinegar into the container. Soak the clean chicken bones in the vinegar overnight.

What will happen:
Check out the bones after they've soaked in the vinegar overnight. Are they softer or harder? Be sure to throw the bones away in the garbage after you're finished.

This experiment identifies the sugar content in food. Sugar is a major factor in the growth of plaque and tooth decay. Note: an adult must supervise this experiment.

What you'll need:
1 bottle of Benedict's solution (ask the school Science department)
assorted small pieces of food (cookies, crackers, bread, fruit)
several glass test tubes
1 heat source (burner, gas or electric)
tongs

What to do:
Place a piece of food in each test tube and then pour 30 - 40 ml of Benedict's solution over the food. Heat the test tubes one at a time over the burner, using the tongs to hold the test tubes.

What will happen:
Benedict's solution is blue. The presence of sugar will turn the solution to orange. Are there some foods you thought were sugar-free that have sugar?

What to do: put the glove on one hand and hold your hand with the fingers extended but tightly together, pointing upward (your hand with the glove should look like you1re going to give your friend a ":high five":, or how a policeman holds his hand up to stop traffic). Spread your fingers apart and have someone spread peanut butter between your fingers ­ make sure to get the peanut butter deep between your finger joints. Tighten your fingers together again. In this experiment, your fingers represent your teeth, and the peanut butter between them is food that gets trapped between your teeth when you eat. With your fingers still tightly together and held upward, use the toothbrush and toothpaste to try and scrub the peanut butter away (remember not to move your fingers apart!). Have someone else try to remove the peanut butter using the dental floss between your fingers. Which does a better job ­ the toothbrush and paste or the floss?

What will happen: a toothbrush simply can't reach all the places between your teeth. Dental floss can do a much better job of removing food between your teeth. If it's not removed, it can cause gum disease and cavities.
