Look younger with Whiter teeth. GLO Science.

They say if you aren't whitening, you're yellowing.

We associate beauty with youth, and for some reason baby teeth are just naturally freakishly white. So if you're not whitening, your smile might be making you look older than you are.

Teeth whitening has come a long way these past few years. Who hasn't heard of Crest WhiteStrips? Yes, they work, but only if you're VERY patient and willing to put up with the goo and mess in trying to keep them in place every time you use them. Speaking of, you'll need to use them a lot to see real results.

And we've all heard of ZOOM, the fastest way to whiten, especially how painful it is. The sensitivity lasts a long time due to the strength of the bleaching agent that's used.

So if you're looking for a solution to whiten quickly without sensitivity, there is a new at home device on the market that you should know about called the GLO Brilliant Personal Teeth Whitening Device, $199 Available at Sephora and gloscience.com.

This system was developed by a dentist, Dr Levine, and is a new approach to whitening using heat and light with a patented gel formula. Dr Oz named it one of his top anti-aging products and beauty editors swear it's the easiest way to whiten teeth without sensitivity.

It looks like an iPod, but easier to use. Charge it up, apply the gel to your teeth - connect the mouthpiece and press power for 8 minutes to get one step closer to whiter teeth. Up to 5 shades whiter in 5 days, without sensitivity. 

The set comes with 10 G-vials of gel which is enough for 40 applications or sessions. By purchasing additional mouthpieces everyone in the family, over 12 years old, can have beautiful pearly whites. I think Americans now have the whitest teeth in the world!
