Before I say anything, I want to make clear that this is not a paid review. I’ve suffered from yellow teeth as long as I can remember. I also tried this popular so called Ayurvedic toothpaste for couple of months without any progressive result. So I decided to give this Colgate toothpaste a shot and I got a remarkable result from a single use. Not only did it give my mouth a certain feel of freshness but also gave my teeth a whiter shade. I don’t know if it depends on the person’s teeth but in my case it worked like an absolute charm.
