iWhite Superior Teeth Whitening Kit - 10 Trays - Professional Teeth Whitening Up to 8 Shades Lighter. Whitens and Restores Enamel - Clinically Approved - Microbeads, Calcium, and Xylitol

Seem to work fine

I am really impressed with these teeth whitening guards as after only one application my teeth were noticeably whiter!I'm a big coffee drinking which has obviously taken it toll of the colour of my teeth, despite brushing my teeth twice a day with whitening toothpaste for sensitive teeth.In the past I've tried using teeth whitening strips which were very fiddly and my teeth felt very sensitive afterwards but these guards from iWhite are so easy to use and didn't cause any issues regarding sensitivity. They simply slip over your teeth and work their magic for 20 minutes.

Can’t see a difference. Used as per instructions, I really should stop wasting money on these products. Nothing works. I don’t understand the good reviews. There’s one obvious fake photo I reported on here.

Very little & slow results.Not good value.3 stars because it’s convenient - good idea to have pre-filled teeth strays

So I thought I would try this brand as have had unsuccessful results from others. After a week I saw pretty good results! I will say that it obviously does not work on crowns as you can see one tooth is not as white but was really happy overall with the results and went for a 2nd box and definitely happy with the results after 2 weeks!! I will definitely be purchasing again!!!

never done nothing

Not used enough to give a fair review of how it worked but the bits I’ve tried isEasy to use

amazing product I have only used once and the whitening effect is dramatic!my teeth have never looked so white. I uses for 20 minutes just before bedand wake up with fresh pearly whites!used the classic one as well and was equally amazing I just put one for 20 mins after brushing my teeth while I do my make up in the morning and can definiely see the difference!
