Go for it!

I'm very sensitive to whitening strips tho those are the best DIY home teeth whitening product on market (from my dental hygenist friend) so she suggested me try this. It works! It is little annoying your have to do it 3 times (30min total) a day for 7-14 days in row and once every once a while to keep up. I'm a heavy tea/coffee drinker and my teeth are super yellow. This really works! No sensitivity at all and I can see difference from day 4. I used it for 14days in row then once a week to keep my teeth white. Love this.

My husband bought me this teeth whitening device because I spend hundreds a year on whitening strips as well as getting them professionally done at the Dentist. We heard a lot of great reviews on this product so thought it would be worth in investment and it works amazing!!

Basically you apply the gel on the bottom and tops of your teeth, then you put the mouthpiece inside your mouth firmly on your teeth. It will product a nice warm sensation in your mouth while its on. You must leave it in your mouth for approx 7 minutes until the light shuts off. I noticed a HUGE difference in just once treatment...After 6 treatments my teeth were so white my husband started too question in and starting using it himself. He smokes so it has greatly reduced the yellowish color on his teeth. If you have very stained teeth it may take up too 8 treatments too really see a difference. My teeth are pretty white as it is so it didn't take many treatments to get the result I wanted.

You can buy this at Sephora for $300. Worth it because it costs $300 just for one treatment at the dentist. And you can do as many as you like just have too buy the gels.
