Toothpastes generally have 20-40% of water in them to prevent drying. Aside from that however, most of them have abrasives which are what polishes or cleanses teeth by grinding (an example of one is baking soda).

The most common flavor added to the majority of toothpastes is mint because it not only allows people to have a "cooling" sensation when finished brushing, but also improves their breath and causes their mouth to feel "fresher". Fluoride is also a commonly used ingredient in toothpastes. However in these Colgate toothpastes, they may not contain fluoride which could help prevent teeth decay as some scientists discovered fluoride would do (thus creating controversy over whether or not it is good to use fluoride).
