It is my personal experience that few year back I was using other brand of toothpaste. I had cavity problems in my teeth. I try many brands of toothpaste. But once I choose colgate from last 1 year, cavity problem solved with this toothpaste. Now Me & My family using only colgates. and would like to suggest this brand to my colleagues and my neighbors. it is really very useful and perfect choice for toothpaste.
