Want to polish your pearly whites—but don’t have the cash for expensive tooth whitening treatments? Don’t worry! Here’s a quick and easy-to-make whitening paste you can whip up at your kitchen counter.

Just mix equal parts of sea salt and baking soda in a shallow cup. Add 2 teaspoons of lemon juice to the mixture. Now, dip your toothbrush in the paste and start stroking. Brush each tooth surface and rinse well. Using this paste once each day can help give you a brighter, whiter smile!
