Aquafresh White Trays, 14 Trays

After reading some of the reviews of this product it made me realize many people are VERY hard to please. 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 read several reviews before buying the product and there are people who absolutely love it and those who swear wouldn't buy again. I'll try to be as objective as possible...

Effectiveness:
The product works. It whitens my teeth after the first use, and the result became very obvious after 3 uses (as it claims), so I'm pretty satisfied.

Tray Design:
The tray fits my mouth quite well (but I have a small mouth... I even wonder how it would fit bigger mouth since the tray is kinda small.) Spreading the gel so that it fully covers the teeth isn't easy. I noticed that the top part of the teeth are whiter than the bottom (especially the bottom teeth.)

Side Effect:
The gel DOES hurt the gum. I read other reviews and people have been complaining about bleached gum. My gum didn't get bleached, it didn't turn white, but it bled!!! The part of the gum closest to the teeth turned red because of the bleeding and there's also minor...Read more

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 alot of whitening goo that you press into your teeth and it helps the trays stay in place. The first morning 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. It really isnt as bad as the other reviewers make it seem.
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 in the future.
