I've heard that a certain brand of toothpaste does not contain fluoride. Is this true?

Yes, it is true. Certain brands of toothpaste do not contain fluoride. Fluoride is added to most toothpastes in order to prevent tooth decay and cavities. However, some toothpastes are marketed as being fluoride-free because they have other ingredients such as baking soda or hydrogen peroxide which can also help reduce the risk of tooth decay.
