I just started using it today, and FROM FIRST USE, it made white spots appear on my teeth which were never there!
I googled this and it is common with not so good whitening kits. I have been whitening my teeth with whitening reputable toothbrush brands and never had this happened.
This product is a piece of crap and if these white spots don't go away soon I will file a lawsuit for this poor result.
Bottom Line: No, I would not recommend this to a friend

Company Response from HiSmile
Hi Jad, a possible cause of these spots could be due to fluorosis- I can assure you that this is nothing to cause concern as this can happen with any form of teeth whitening product not just HiSmile.
If you have fluorosis, using our kit will exaggerate the calcium deposits in your teeth making these parts extremely white. This is not permanent and you should notice that the spots subside within a couple of days of completing the applications as you mentioned this is a common occurrence across all whitening processes.
We use all natural ingredients to ensure no sensitivity or discomfort when using our products and avoid harsh chemicals such as peroxide as these actually magnify the effects of fluorosis which is one of the many reasons why we avoid adding peroxide to our formula.
Please get in touch with us via email - help@hismileteeth.com as we would be more than happy to assist you!
