My dentist recommended this toothpaste to me as I was looking for something with nano hydroxyapatite that did not contain baking soda, which is very harsh for people with sensitive teeth. Most of the other brands like Risewell and Boka all had baking soda. I was using a very expensive $36 a tube medical grade nano hydroxyapatite from Japan, but because it had sodium laurel sulfate a.k.a. SLS it was causing sensitivity as it was removing my natural biofilms. contrary to some of the reviews above glycerin is not bad in toothpaste, and will not prevent your teeth from absorbing nano hydroxy appetite nor is it sticky or cavity causing. This toothpaste is not super sweet like others have said, in fact, I don’t notice the sweetness at all, and I am a person who hardly eats sugar. The one thing that takes some getting used to is the wateriness of the toothpaste, and as others have said the fact that it does not foam up due to lack of SLS. I find I need to use a little more of it because of the watery texture. It also has a slight strange flavor, almost like the smell of marijuana, but this does not linger or stay in your mouth. I can overlook all of these things if this toothpaste is actually going to help me. I have used it for a few days now and have noticed my teeth feeling cleaner. Before nano hydroxy appetite, I was using medical grade fluoride, toothpaste that needed a prescription and the feel of this toothpaste reminds me a lot of that fluoride toothpaste in that your teeth feel really smooth after use. FYI Fygg stands for feed your good guys. So far I’m happy with the results.Edit: I have been using this now for a month straight and it has helped with sensitivity but the tooth that has some gum recession it has not helped like the medical grade nano hydroxyapatite was doing. I am using the Fygg on all the other teeth but still having to use the medical grade hydroxyapatite on the one tooth. I have no idea why this is but I’m guessing because Fygg is not medical grade so the hydroxyapatite is not as strong :-(Please fix this because I would like this to be my only toothpaste :-)
