Patanjali Dant Kanti Advanced Toothpaste is not at all advanced. It makes your teeth yellow after using it for a month. It has a not so pleasant fragrance to it which stays in your mouth for a while. After brushing it leaves your mouth dry. They promise to make your teeth strong and healthy but they have failed to do use even after using it twice daily. It just takes away the whiteness of your teeth and makes your gums dry. I would not recommend anyone to use this product. It is available at a reasonable price in the market but saving money on it will only make your teeth worse and later on you will have to spend more money on your dentist visits.
