Once I went to a tour for 5 days and when I was doing packing of my useful stuff then I buy a small pack of close up deep action toothpaste for me to be use for those 5 days of my tour and when I start using it regularly , I notised after 2 days that it was not cleaning my teeth properly and gets no effect on my teeths . Aftet using it for 5 days when I was back to home their were many problems occur in my teeths like pyria an my teeths got yellowish appearance . But one thing I like about this toothpaste is taste of it. It smells fresh and taste is good too.
