You want your teeth to be more white? Than you should drop by the Brite Smile. The dentists and nurses over here are very friendly and funny. You can go in and get your teeth whiten within hour. And it does last on your teeth at least 2 years. If you like you can also buy the brite smile pens home and brush on from time to time. I just had my teeth done few months ago. Still now it's really white! I really like it. Whenever people see my teeth, a lot of them would ask me how I did it! Compare Brite Smile to those regular Crest White Stripe... it's expensive but it last you longer time! Plus you don't have to wait 7 or 14 days to see the result!
