MySweetSmileDentist-Approved Teeth Whitening Powder - IndyBest Award-Winner - Enamel-Safe & Sensitivity-Free - Cool Mint Flavour - Removes Years of Stains - 6 Month Teeth Whitener Supply

This is a good lightening powder, I noticed a difference after 3 days, using it twice a day, my teeth feel a lot cleaner too. I have really sensitive teeth and haven't had any sensitivity since using it. I used the word lightening as it hasn't made them white, but I'm happy with the result and will keep on using it as it has definitely made an improvement.

Face it, your teeth may not be naturally white any more than your eyes might be blue, so without - sometimes painful, usually expensive - cosmetic alteration, they're not going to be WHITE white. But with this product I can guarantee that after two or three weeks you will be noticing that your teeth look much brighter, so, yeah, give it a shot.

I can see a difference after a few days! I have crowns so try to keep away from them and only lightly go over the dental work but my teeth are definitely brighter and I can see that if you use twice a date for 2 minutes each time it will work!

Looks works and tastes like eucryl. It's basically very expensive chalk. It does whiten teeth but only in the way cif cleans hobs. It's an abrasive... Don't use it too much!!Save yourself a lot of money and buy eucryl.

I honestly don’t understand how this product can possibly work if it’s only used once a week, as per the instructions. I went thru four containers of the stuff, used it every day for four months. After two months I noticed some whitening. After four I’d say my teeth are a shade or two lighter. The reason for giving it one star is purely the expense. I’m shocked they’ve hiked the price up to £23 from £19, just a few months after putting it on the market. Seems to me this company have a ‘smash and grab’ approach to retail as the ingredients are surely not expensive.

Easy to use, taste is fine and it definitely works!

Been buying this a few times over the last few months and its usually very good but my recent the other day order the packaging is different and sadly so is the product it is no longer effective as it once was it uses to be almost gritty but no it is very fine powder and sadly does not work :(

Really good always sceptical. However noticed difference in first use . A while on and can barely notice difference between the few teeth thar was brown and my good teeth . Will be kept as my daily routine. Tastes a bit like the drink from dentist, which isn't to bad but can brush with normal toothpaste straight afterwards which I do
