I suggest you to go to your dentist and have it done. There's a lot of ways to make your teeth white and I am pretty much sure that dentist knows best. Or If not why dont you use toothpaste that can whitens teeth. I prefer, you better use products from nu skin they have this AP24 whitening fluoride toothpaste.To convince you more I personally use AP24 toothpaste. And I tell you it works.
