10 Teeth-Whitening Kits That Actually Work

Zimba Teeth Whitening Strips ($20, originally $25)

The Zimba Teeth Whitening Strips take up to two weeks for full results, though you may see results in half that time because these strips get the job done. These no-slip strips can be left on the teeth for 30 to 60 minutes, and are great for those who have sensitive teeth as well. Unlike other options, these come in a variety of delicious flavors, so you can actually enjoy the whitening experience.
