From few months ago I used it for a long period of time and really I did not felt the difference , it cleanses all exta dirt from your teeths but does not seems to be clear because teeths look yellowish . The flavour of the toothpaste is very strong , it feels disturbing in the beginning . It have no effect on sensitivity and cleansing . The cost of toothpaste is normal as other company toothpaste . I do not recommend it to any other as it does not have any good quality and good changes for teeths , therefore choose any other toothpaste with real ingredients & benefits
