What is the best toothpaste?
Hmm, I guess I'm looking for something that does all three.
In that case, you might want to consider a toothpaste that contains fluoride, which can help protect against cavities, as well as ingredients like baking soda or hydrogen peroxide, which can help whiten teeth. As for sensitivity, look for toothpaste that contains potassium nitrate or stannous fluoride. Some popular toothpaste brands that offer these benefits include Crest, Colgate, and Sensodyne.
