Does whitening toothpaste have baking soda in it?

Baking soda is found in most toothpastes, but the harmful chemical in them that you need to watch out for is fluoride. This can hurt the enamel that protects your teeth from the food you eat and the bacteria in your mouth. I recommend that you should either get a toothpaste with no fluoride in it, or just use baking soda mixed with a little salt.
