So I'm not too sure how they get the coral for this toothpaste, but coral is already dying off.I can get past the fact that this toothpaste has no taste and does not foam up. What I can't get past is that it does not clean. My teeth still feel dirty no matter how long I brush for. It is almost like it presses the grime onto my teeth. It takes so much work to actually get my teeth clean after using this toothpaste.
