whell no duh rose1119... the best way is to get a tooth paste with baking soda and oxygen bubbles or... you could do it the old fasioned way: dip the tooth brush with toothpaste on it in a box of baking soda and brush :)
Floss, brush used mouth wash and baking soda helps whiten teeth. They have tooth paste that has baking soda in it. Eating apples and chewing gum can help. These make it to where you produce more saliva and that helps.
