chosen: You can whiten your teeth at home using several different methods. The simplest method is to use a teeth whitening kit that includes whitening gel and a mouth guard. The mouth guard allows you to use the gel only on your teeth and keep it in place overnight. You can also use baking soda and hydrogen peroxide as a DIY whitening paste, or you can scrub your teeth with baking soda and hydrogen peroxide for a whitening effect. Finally, you can also whiten your teeth using activated charcoal, which can be used as a whitening toothpaste or scrub.
