MySweetSmile Dentist-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.

I've been using this product for about six weeks and really cannot notice any difference to my teeth but have noticed that persistent bleeding gums are now no more after years of suffering. So four stars for that reason.

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!

I have only just started using this, so I have not seen much difference yet but the powder leaves your mouth smelling fresh.

Unlike the Amazon prediction that it would take quite a number of applications of this powder, after a strict following of the instructions for use, my teeth were very noticeably whiter after ONE timed application! I drink two cups of black instant coffee a day and have been doing for many years, so this product leaves me extremely impressed!!

I think this may be my first Amazon review, but honestly so impressed with this I had to write one. I have had an annoying tea/coffee stain on my front tooth that developed postpartum and I haven’t been able to shift it since. The dentist told me I’d likely need to get proper teeth whitening treatment (which costs around £250) if I wanted to get rid of it. Tried this after reading the reviews and after four days of use, the mark is more or less gone!! The photo doesn’t even do it justice. Already feeling more confident. Very happy.

It's too early to review since I only received the item 2 days ago.

Great product but an absolute nightmare trying to get the inner lid off. Tab needs to be longer.
