harmful to your gums? I read about making a toothpaste of hydrogen peroxide and baking soda, I've only used it once and I know not to use it more than once a week but does anyone know if it can be harmful? and does anything else work besides the expensive kits?
--------------------
Stores such as Family Dollar sell generic pre brush whitener(works well) most of these products contain peroxide.Certain Toothhpaste contains baking soda and peroxide which my dentist says if safe.
