Back in the day, buying toothpaste used to be very simple for me: check which one is on sale, and than buy it. Than my dentist told me something that I already knew, that changing your toothpaste up frequently may not be the best thing for your teeth. He told me to use Colgate total, which I have been using ever since. Aside from tasting great, it is also available everywhere, at an affordable price, it is not too runny, not too flaky, foams just enough, and is available in a variety of flavors, and thus gives different options for the same quality. It also provides protection, something that a toothpaste is designed to do anyway.
