This toothpaste does exactly what it describes - cleans sensitive teeth. It doesn't cause pain, the taste isn't intense (especially compared to common brands), and while I wouldn't say it whitens, it does help teeth look cleaner overall and feel healthy. My dentist recommended it to me and it's all I use now. My teeth feel good and do not ache or hurt. This would also be a great option if you whiten or grind your teeth and they feel sore. The price could be more reasonable, that is the only reason I dinged a star.
This is the only toothpaste we use! I have really sensitive teeth and notice a huge difference when not using.
It actually keeps my (old, tea-stained) teeth white without making them sensitive.
