Whiten your teeth the inexpensive way

I lost my whiting tray the first week I got it. I was planning on making an appointment with my dentist again just for a new tray. I found this great tutorial on youtube.com on how to create your own whiting tray at home for only a few dollars. You can also use your homemade whiting tray with over the counter whiteners. Sounds good to me. I can't wait to give this one a try.
