I have used Colgate, Pepsodent and other toothpaste for many years.But all these tooth paste have least effect on your’s teeth cleaning and in fact these toothpaste surely make your teeth not so strong but also they increase gum problems of your’s mouth.These lead to mouth decay and your’s teeth will pay for it .Because I use this toothpaste from 6 months now . All the problems relating to my teeth and gums are now vanishing .best best best toothpaste.
