As we know the close up toothpaste is the most popular brand in the all over world but I dont like this tooth paste. about 2 to 4 month before I was using this tooth paste daily when I washed my teeth in the morning and in the evening I was feeling that the teeth and gums were so sticky type. I observed that particular experience in the daily basis. and finally I left this tooth paste.
so this is the reason that close up is not very effective this is my experience.
