Thank Heaven they changed from a metal tube to plastic. I removed a lippie because it is overpriced and I removed another because the tube is filled 1/3 of the way with air. If they're going to charge 20 bucks for toothpaste, they should have the decency to fill the darn tube up. My teeth have gotten noticeably yellow since I've begun using this over 9 mo. ago. I dont know if the toothpaste is to blame or if it's because my tea and coffee drinking is catching up with me. HOWEVER, I love that this does not contain Fluoride. Flouride is VERRRY bad for you. Check it out on the internet, it's truly scary. And it is sooo hard to find a toothpaste that doesn't have fluoride in it. It also has a nice numbing effect, so if any part of your mouth is sore, like from flossing, this helps. I like the taste, contrary to other reviewers, it does not taste like dirt. I actually have never tasted dirt, but I dont think this is what it would taste like. I think for some people, it's a mental trick because it looks like mud. I like it that its not super duper intense, bitter, in-your-face mint because those kind of toothpastes make me gag first thing in the AM. And that makes me dread brushing my teeth. I will buy this until I find a better non fluoride paste. EDIT: I just purchased five tubes of this, all of which were less than half full. It says on the tube that it is 4.4 ounces, but I squeezed all the air out and compared the smooshed tube to a 2 ounce tube of face cream I have and they are equal. Why lie and say it's 4.4 ounces when its actually 2? I don't like being lied to and I don't like paying 20$ for 2 ounces of toothpaste. I'm going to check out darphin.
