I have used this toothpaste for about 6 weeks. It has made my teeth less sensitive. Before, when I would eat lemon, my teeth would hurt for days, especially after brushing. Since using, they either don’t hurt or it’s mild and only after the first brushing following eating lemon. This has been great!
I bought the toothpaste initially as I have enamel loss. According to the instructions, it takes a few months for the toothpaste to work on this so this is why I have given a 4 instead of a 5 because I have not seen this effect so far with the length of time I have been using it.
