DENTAL HEALTH!

Our teeth have a “shell” called enamel to protect them. A tooth’s “shell” is similar to the one of an egg. We put an egg in water, two in coke and two in vinegar till the following day.

RESULTS:

The eggs in coke were stained.

The ones in vinegar were soft and had lost their shell.

The egg in water hadn't changed.

Bacteria in our mouth form a sticky material called plaque. These bacteria “eat” the sugar and food in the mouth and form acids like vinegar. These acids break the “shell” that protects our teeth and cavities can “attack” them.
