Patanjali dant kanti is really very good paste for lot of problems to teeths. I have used this product for lot of days it really works to make my teeth strong after using one month I found that I am getting relief from yellowness of teeths and I got to see that my teeths are getting more white than before. It is having a smell of laung .when I brush my teeth with this paste it really makes my mouth fresh and it also make free of sensitivity .But the bad thing I have seen by using this patanjali dant kanti is that it makes my gum swollen and the other thing is that it is made up of some spices which I really don, t like it other than this it is really a very good product by patanjali it makes the teeth better more strong and makes more white to my teeths. And it is also cheaper than any other paste.
