will it be harmful to my teeth ?
--------------------
issy, this product is scam, so never use it.I'm using teeth whitening toothpaste plus a product which I found recently and they work like a charm for me. I'm using crest teeth whitening toothpaste. Also if you're interested in the product which helped me a lot, you can have a look at the blog below: http://myteethwhiteningstory.wordpress.c… it won't damage your teeth enamel. Hope this helps
