These are great, but I don't notice a difference between these brush heads and the regular ones. However, I am glad that I don't have to think about gum health too much when I use it. My dentist did say he saw better gums over the last time I went, but I also started flossing more, so can't say it was just because of the brush heads.
I didn't notice much whitening, but it does taste great! My mouth always feels really clean and fresh after using it. I use this every day, at least twice a day. It's cheap, so you're getting a pretty good deal with this toothpaste. I would buy this again.
