Hi. I am sharing my personal experience with you friends. Senstivity is one of the most serious problem arising day by day. I also have Senstivity problem from last 3 month so someone suggest me to use sensodyne and yeah after using a couple of week, I experience a lot of relief from Senstivity. Now I am able to take sip of tea and also drink cold water. The direction to use this product is use it twice daily and don’t be irregular with it. I would recommend this toothpaste.
