Well toothpaste must be fluoride but this Colgate put the adverse affect on me. It totally waste of money after purchased it. Worst toothpaste is available in market. Flavor is minty which made me felling of disappoint . it says that having cleansing effect within 1 week but this is completely fake. I tried for 2 weeks twice a day but didnt work at all. No improvement is done to my teeth even after 2 week so rather it also donot gives fresh smell. Hence I highly recommend you not to buy as it is has fake promise made by Colgate on its tooth paste.
