started oil pulling a few months ago and was using a different toothpaste after. switched to this one and the combination is noticeably better. like the oil pulling + this formula feels like a full system. sensitivity around two of my molars has really calmed down. I eat a lot of acidic stuff (vinegar sauces, sparkling water constantly) so having teeth that aren't screaming at me is great. one inch strip lasts a good while too, tube has been going for over a month and barely looks touched
