This Natural Toothpaste Only Requires One Ingredient -- And You Already Have It

Sure, we've all perfected a method to squeeze every last bit of toothpaste out of the tube (or even bought a gadget to help), but have you figured out what to do when you don't get enough — or worse, none at all?

In the video above, Refinery29 replaces everyday toothpaste with a blend of baking soda and water — and it seems to do the trick. Baking soda is a balancing ingredient that can be used in a wide variety of ways, from leavening baked goods to reducing acidity to brightening laundry and even calming an upset stomach.

But if you decide to make the permanent switch from fluroide-based toothpaste to a baking soda solution, don't be surprised if you end up with a few cavities, says registered dental hygienist Krystal Hurteau, owner of Krystal Clean Smile Clinic. According to Hurteau, baking soda can be used to brighten smiles and battle bacteria, but it is the fluoride that prevents the development of cavities.
