Foods That Whiten Teeth Naturally

Cheap home remedies that work

Baking soda, an old-fashioned home remedy that works to whiten teeth.

Use baking soda to whiten teeth. — Niday Picture Library/Alamy

4. Baking soda

One 2008 study found toothpastes that contain baking soda — long considered a tooth-whitening home remedy — do a better job of removing plaque than toothpastes without the ingredient.

To try it, your best bet is brushing with a commercial paste that contains the mild abrasive.

Or, once in a while, you can just brush your teeth with baking soda straight from the box.

Next: Pass the cheese, please. »
