Go Smile On the Go Teeth Whitening Pen
Portable whitening pens like this one from Go Smile won’t drastically lighten your teeth due to a lesser percentage of hydrogen peroxide, but a lower dose of the active ingredient also means it’s less likely to irritate teeth. True to its name, it’s a good pick-me-up for on the go — use as needed after teeth-staining culprits, like coffee and red wine. The wand “does brighten up my smile and my teeth everyday,” a user remarked.
Bite Whitening Gel
This simple (plastic-free!) teeth whitening kit from Bite contains a bottle of carbamide peroxide gel, which tends to be milder on teeth, plus a small brush to paint on the no-rinse formula. While the GH Beauty Lab hasn’t tested this, reviewers raved about how well it works and liked that the brush allows you to target specific discolored teeth.”It’s very simple, just painting the whitening gel on your teeth and waiting two minutes, and I have noticed a significant improvement in my teeth color,” one said. Note that the gel formulation may clump after repeated use.
