does not work for me [SEP] i saw the reviews for this toothpaste and decided i would give it a try instead of paying my dentist for expensive teeth whitening i also opted for this one over all the other brands because for years the only brand i use colgate totali grabbed tubes because they were on sale and have already used whole tube and have started on the second one i can not detect one ounce of difference neither can my dentists assistant my teeth are the same color as when i started i would understand it not working if my teeth were extremely discolored but they are only slightly discolored but still very noticeable to me curse my childhood of drinking teas cola lol i even bought the special optic white toothbrush which i absolutely love btw because it was supposed to help with the whitening but still a no go it is a good toothpaste as a toothpaste but as for whitening it does not work i am glad that it is working for other people but it has not worked a lick for me which is a bummer i really had high hopes i guess i will finish this current tube and go back straight back to my total if your looking to buy it i would give it a try because even though it did not work for me it might work for you
