This toothpaste is terrible. I received a sample from the dentist, and it seemed fine, so I bought a larger tube on sale. Big mistake. The formulation is different for some reason in the small versus the large tubes, or at least the large tube I purchased. Maybe I just got a bad batch. First of all, it is gritty like sand. Not gum-friendly. Second, it is slimy, and oozes out of the tube because the cap doesn’t close all the way. The tube stands on end and the goop seeps out and makes a mess of everything. I’m going to have to throw it out, which upsets me because I don’t like wasting things. I even tried laying the tube on its side and wedging the cap closed, but the leak was even worse. It’s like a gritty blob trying to devour everything in its path. Forgive me, teeth and gums, for foisting this product on you.
