Even though I'm pretty happy with the whiteness of my teeth, they do seem to get a little dull every once in awhile, so I touch them up whenever possible. (I'm too scared to get them whitened professionally because my sister had it done once and she said that it hurt WAY more than she ever expected it to. The results were amazing, but seriously, they were so white that every time I looked at her, I kept picturing that "Friends" episode where Ross had it done and his teeth ended up glowing in the dark and I would laugh every time she opened her mouth. I can't imagine why she was so annoyed with me!) GO SMile has launched a new Smile Whitening Light System (that's Whitney Port checking it out above) that's the first efficacious (don't feel bad if you don't know what that means, I had to look it up too) white LED light whitening device available over the counter. I'm intrigued because it's clinically proven to whiten teeth up to 6 shades in only one 30 minute treatment. (That's less time than I waste watching one "Jersey Shore" episode!) I've tried their whitening ampoules before and really liked them, so I'm definitely going to have to get my hands on this to test it out. (The 30 minute treatment is comprised of 3 consecutive 10 minute light sessions used along with the Smile Whitening System ampoules, so it seems really simple and straight-forward). You can find the system at Nordstrom stores or on gosmile.com. Let us know if you've tried it!
