I was using colgate initially but one of my friend s told me to use pepsodebt 2in one because my tooth started to become yellow . Therefore I started using the paste but it didn’t help muchit has a very strong flavor and leaves a bitter taste at the end. And I could not see any kind of improvement in my teeth even after using it regularly for about 3 months. Overall it is not very good paste therefore I would v suggest you to go for some other paste because of the taste it would make your mouth bitter for some time after You brush your teeth.
