This experiment aims to demonstrate how toothpaste protects our teeth. When our teeth are exposed to acidic drinks such as soda or coffee, it starts destroying our teeth which can lead to several things such as cavities. However, if we use toothpaste and brush our teeth, this allows for the minerals found in the toothpaste to fight off cavity bacteria and regrow the important minerals on our teeth so they can be strong and have a bright white smile to them!
