Doesnt work well at all
I have tried this 4 times in 6 days and i dont think it works. Usually there is a bit of foaming in the mouth , there is none with this.  Cant tell if teeth have whitened at all.  Disappointing.... :-(<br /><br />1.  No instructions<br />2. No specifications of product on box.<br />3. No expiration date<br />4. Nothing mentioning ingredients, not even on the syringes
