Luster Tooth Whitener Review

We Test Out a Light-Up Tooth Whitening Kit

Getting brighter teeth at home usually means wearing whitening strips for a couple of weeks. But if you're more of the instant gratification type, Luster One Hour White ($40) aims to whiten teeth up to six shades in an hour. Like other whitening products, it uses hydrogen peroxide to lighten. What's unusual is its activation light, which mimics in-office treatments used by dentists. I tested it out, so for the pros and cons, read more.

The good:

  • As promised, my teeth started looking whiter right away. It's satisfying to see your chompers get brighter with each round of treatment.
  • The process, while more involved than whitening strips, is simple: rinse, paint the whitening solution on each tooth, then hold the light to teeth for two minutes. Repeat 10 times and you're good.
  • I didn't need to take all 10 rounds, since I was happy with results after five.

The bad:

  • Despite its promises of zero tooth sensitivity, I definitely felt the peroxide hitting my teeth. It wasn't exactly painful per se, but it didn't feel good, either. So there's that.
  • Painting the solution on each tooth requires attention to detail. If you are clumsy or rushed, results might be uneven.

Overall, it's a clever take on tooth whitening. If you have sensitive teeth, skip it. But if you want whiter teeth now now now, it might be right for you.
