After using this toothpaste for 2 months, all I can say is that I will never ever use it again. I had experienced sensitivity after the first week of using it and after 2 months of continuous usage (day and night), my teeth began fading to yellow due to the abrasive ingredients in this toothpaste. I thought it would get better but it obviously didnt. Secondly it has a horrid taste so if you have a partner and want to scare them away, use this toothpaste.
Never will I ever use this again!
