Watts Power Pro 35% Teeth Whitening Gels - 4 Huge 10ml Gels Plus NEW FCP Enamel Gel / 40ml

You can imagine my surprise when I found out that this stuff was available without a prescription, and was fairly inexpensive. The bottom line: IT WORKS. It works REALLY well, and it starts working with the first application. I've used it 3-4 times and my teeth are SEVERAL shades whiter.

Some tips:

1. This won't work as efficiently if your teeth are gray-ish, as opposed to yellow-ish.
2. You can apply this by placing the gel inside the tray, but I found that wiping them directly on the teeth and THEN slipping the tray on was more efficient.
