Professional teeth whitening isn't cheap – and even the home whitening kits are a bit of a splurge. The good news is that you can whiten your teeth without using either one.

Just wet your toothbrush, and dip it into a box of baking soda. Then, brush your teeth, and rinse. Repeat regularly, and you'll have whiter teeth at a price that you won't feel guilty about.

Why This Works

When mixed with water, baking soda creates a thick paste that's perfect for scrubbing away the stains on your teeth, and because it's applied with a toothbrush, it even does a good job of reaching and removing the stains that form between your teeth – something most whitening kits can't do.

The Benefits of Baking Soda Whitening

Baking soda is the clear winner among whiteners when it comes to price, but that's not its only benefit. Baking soda is also:

• less abrasive than most whiteners
• all-natural
• gentle on gums
• gentle on enamel
• easy to use—no strips or messy trays to fool with
