White Smile Eco. Meanwhile, I've spent five out of six days on it. White Smile Co allowed me to test a home teeth whitening kit for you. A safe set to try out at home. It is also easy to use and can only be lost 15 minutes a day. For me, that was 15 minutes that I compulsory rest and didn't do 20 things at the same time. The set is now available for 40 euros on the White Smile Co website. What does WhiteSmileco itself indicate about this product? “Nobody wants discolored teeth. That's why we combined three ingredients to create a high-quality gel formula to make your teeth whiter and stronger, without sensitivity or damage to your teeth. Our product has been medically tested, scientifically proven effective and completely peroxide free. Our teeth whitening kit provides an effective and fast way of teeth whitening, but safe for teeth, tooth enamel and gums.” What's my own experience? Well, the pictures actually say everything, because I really see a difference in the mirror! The top left photo is in front. The photos at the bottom are after. My teeth are whiter, more beautiful and I feel more confident about this. Also, this set is certainly safe for your teeth because I haven't felt any irritation for a moment. For me a really top product, which really works!
