4. Hydrogen Peroxide

Hydrogen Peroxide can be a very effective home remedy for teeth whitening as it contains a mild bleaching ingredient that can help you achieve the same results as those costly teeth whitening procedures. All you have to do is make a paste out of hydrogen peroxide and baking soda, which you will then use to brush your teeth with (be sure to be gentle!). Later on, you can follow up with a brushing using your regular toothpaste.
Hydrogen peroxide is another ingredient that you should use only in moderation. Overuse can cause gum irritation or make your teeth extra sensitive – which is not something we want!
