If Crest Whitestrips feel too harsh, expensive or time-consuming, here’s a simpler alternative: A $10 mouthwash that just takes 60 seconds of your time. GuruNanda’s dual-chamber mouthwash gave reviewers “noticeably whiter teeth and fresher breath” after a few weeks of use, and it doesn’t even use alcohol or fluoride. Instead, it’s loaded with hydrogen peroxide, essential oils and baking soda — all ingredients that’ll feel much more gentle on your teeth and gums. Nab a single bottle for $10 or a three-pack for $29 and get a mouth product that one reviewer attributes to the “cleanest my teeth have been, ever.”

This mouthwash features dual chambers that mix for a potent but gentle clean.

Instead of a single, large bottle of liquid to swig around in your mouth, this mouthwash has a unique dual-chamber design that mixes when you pour. On one side is hydrogen peroxide, used to break down stains and whiten teeth. In the second chamber is a combination of vitamins D3 and E, seven essential oils including spearmint, tea tree and fennel and baking soda to creates a pH-balanced solution. Just pour 15 milliliters of liquid from both chambers into the bottle’s cap, swish for one minute after brushing and spit!
