Bright White Smiles Natural Teeth Whitening Activated Charcoal Powder

I used the product for 3 days and was really excited about it. However, after the third day's brushing, I noticed that one of my crowns looked gray. I immediately stopped using it and have switched to brushing with baking soda once a day. The gray hasn't gone away and I haven't continued with the charcoal. I'm not saying the charcoal caused the discoloration .. I don't know for SURE. But I'm afraid to continue using it and taking the risk of making it worse. Hope it works for you though!

was a bit apprehensive when I used this the first time since my tooth brush turned so black as I was brushing. Just have to be a bit careful when getting some on the tooth brush since it is such a fine powder but seems to be working and making my teeth whiter than the other things I have tried.

I purchased product with a rebate. I do not use daily and use a variation of products; I think different products and combination of products remove various stains. Looks scary during first use; however, results show over time.

I thought my teeth were getting whiter, but I think it was wishful thinking on my part. Three months later, I don't notice a huge difference. My dental hygenist was lukewarm on the idea of charcoal for tooth whitening, and my dentist was unimpressed with the idea (and the results).

The product does what it suppose to. I am satisfied with it. It definitely whitened my teeth. The only negative comment I have is that it is powder and it is very messy. Other than that it is a good product.

Love this product I was a little hesitant in seeing such a small container when I first got it, but a little goes a long way. I’m a coffee drinker and I can notice this product working on just the first application of brushing my teeth with it. It is a bit messy but I used my Colgate tooth paste to dip the product in and it seemed to help.

3 stars because it worked well and felt clean bit was very messy and abrasive on my gums. I have an electric toothbrush and would recommend using a regular toothbrush to lessen the mess.

I'm using this product to whiten my teeth. The first night I used it (regular toothpaste, water, & dipped in product), my tongue stayed a light blackish tint for a few hours but every time afterwards it has been a nicer/healthier pink right away. My teeth seem to be getting whiter as promised so I'm happy with my purchase. I have sensitive teeth and so far there have been no adverse effects.
