I examined my results after Day 3 of the Aquafresh test. Overall, I would say that there’s been a decent amount of whitening and this is evidenced by the fact that the teeth I haven’t included look dingy by comparison. I can see I am going to have to catch them up.

I haven’t minded using the trays, 30 minutes is not a lot of time to spend if you schedule it during a time of day when you are going to be relaxing and not eating or drinking.

The Pros:

* The trays are very soft and don’t scrape or cut your gums. They conform pretty well to your mouth.

* The trays are pre-filled which means that there is a lot less for you to do. Just position the tray and wait.

* The results are good enough that you will notice whitening in a reasonably short period of time. The three days to noticeable whiteness is accurate.

The Cons:

* The only con I can think of may be caused by my own klutziness. I ruined one tray completely by accidentally letting the gel strip inside touch my finger. It’s incredibly sticky and impossible to put back in the tray once it gets pulled out. Caution: do not touch the whitening gel inside the tray, it will stick to your fingers and ruin the tray.

The Aquafresh White Trays will retail at $34.99 for a seven day treatment. When compared to the price of cosmetic bleaching at your dentist, it’s a great bargain.
