I have spent my hard earned earning on such a waste product that named as glister. I costs me 130 for a small tube. no doubt about the taste and cleansing effect all is great and small quantity is enough to produce for cleaning once.
But I bought to get rid from the sensitivity issue that I did not help by glister.
overall, No improvement at all by using the complete tube. flavor is slight sweet and peppermint quantity make the mouth cool, else wastage of money only.
