If your teeth are yellow or dicolored then have them cleaned by your dentist that won't let you use a whitener. If that doesn't work then you can put a little bit of baking soda and peroxide in a cup and use it to brush your teeth. let it sit on a bit so it has time to bleach out the discoloration. They won't disapprove because you just don't have to tell them, there your teeth and you want them to be whiter. Problem Solved!!!
