I ordered the Polanight Zing, before reading the product reviews and was concerned I wouldn't receive the product. I ordered from
This website as it is a fraction of the cost that I pay from dentist and now I know why. Got all intent and purposes the packaging looks fine and that's where the similarity ends. Whatever is inside the syringes is not the actual product. It is is more diluted and anything that makes you foam at the mouth like a rabid dog should be avoided at all cost. It also has a slight burning sensation on both the gums and tongue. To reiterate I have been using this product, supplied by my dentist, for over 2 years. And it works. I will be paying the higher price from them in future and put buying over the net down to total naivety. The old adage if it seems too good to be true is certainly the case in this instance and certainly not worth ruining your teeth for.
