Naturally Colgate is the most trusted company. Active salt product is not much better. Instead colgate strong teeth is better than this product. Why because it is not able to clear the smell. And it irritates while brushing. The paste is also not smooth in nature. Even its price also more than Colgate strong teeth. It looses its effect after within 5to 6 hours. And it can’t able to clear the cavities . so need to improve this product
