I personally don't like it.
I was pretty confused at first how to use this because the instructions don't come on the bottle. I contacted the company on how to use it and they were pretty rude, actually, and said that it &#34;clearly said on the bottle.&#34; It didn't. There were no instructions whatsoever.<br /><br />They eventually told me that I was to use this like a toothpaste, to apply it to my toothbrush and brush with it. I did find that it whitened my teeth, but I also found that it made my teeth and gums sensitive.<br /><br />That's not why I'm rating this low, however. The reason for that is that the main ingredient in this is hydrogen peroxide, which you can acquire for much cheaper. While this tastes better than just rubbing hydrogen peroxide on your teeth, you're probably likely to get similar results. I also just don't prefer to whiten my teeth this way. I find the strips or trays to be easier and less of a hassle, actually.<br /><br />I purchased this item at a discount in exchange for my unbiased trial and honest review.
