AquaFresh  White Trays, Once a Day, 14 trays

I decided to buy this product before i read the reviews. In my opinion, the trays stay on better than the strip kind. There is a lot of whitening goo that you press into your teeth, and it helps the trays stay in place. The first time, the goo came totally out of my bottom tray but that was becuase i pressed too hard. I havent had the problem since.

I noticed a difference after 3 days, and they are much whiter after 7 days. My gums turned white if the whitening goo touched them for the full 45 minutes and felt tingly and hurt slightly. The pick color returned within an hour.

All in all if you are looking for a product that works, this is a good one. I was truly surprised at how well they worked. I will be purchasing these or the strips in the future - it basically comes down to price, and the price for the trays aren's so bad!

The mechanism of action behind most tooth whitener products is to hold hydrogen peroxide or carbamide peroxide (which breaks down to hydrogen peroxide with urea in your mouth) solution in contact with the teeth for a predetermined amount of time according to the concentration of the particular product. Aquafresh White Trays are no different - rather than a strip they use trays. When hydrogen peroxide stays in contact with soft tissue, especially irritated soft tissue, it is normal for a burning sensation and temporary discoloration to occur in sensitive individuals. The Aquafresh trays do a good job of holding the hydrogen peroxide gel against your teeth. You do have to use your finger on the front of the trays to spread the gel around evenly, but is that really too much work? These are not custom fit trays, so I did not expect a perfect fit. I noticed visible results after a few applications and was pleased with the performance of this over-the-counter product. If you have sensitive teeth then be wary of tooth whitening products as they often increase sensitivity. You can either keep the trays on for a shorter duration or use a potassium nitrate based toothpaste designed for sensitive teeth (Sensodyne, Colgate Sensitive, etc.) for several weeks prior to, and during, the whitening process. This should alleviate a lot of the discomfort. All in all I liked this product better than the strips because the gel is able to penetrate better into the spaces between your teeth ensuring a more well-rounded whitening process

It hurt my teeth and it just plain did not work. Big thumbs down!

Love this product.  I used for 7 days and the results were great.
