This natural tooth powder is better than any paste I have ever used. It cleans my teeth really well leaving a very powerful refreshing feeling that grows on you as you use it. It's fantastic for travel since it's not a liquid or gel. When I backpacked through Europe and then to India, I brought this with me. The 8 oz is incredibly long lasting. The last time I ordered this was 10 months ago in January. Highly recommend this product. I've been using it for over three years now and my teeth have never been cleaner. I have even had the experience where a dentist complimented how clean my teeth were and of course, he had no idea I had switched to this natural tooth powder.Pros:Cleans my teeth in a way that seems refreshing (it does take time to get comfortable with) and thorough.I love that the product is travel friendly. Never had any spills or accidents.No weird smells or discolorationsThe product lasts an incredibly long time (even with multiple family members using it)Cons:Sometimes the lid is a bit sticky and I have to put effort into opening, but it does secure it from any accidents so its a neutral point.Can be very strong and unlike any toothpaste you have had before for the first few times. You will get use to it and you will never remember a time when your teeth were that clean.It does not prevent cavities (in my opinion) nor does it claim that.Overall:The tooth powder is not for the faint of heart, but IS for the all-natural-loving folks who want to have very plaque-free and whiter teeth, or those who want to travel and not worry about toothpaste getting through security.I highly recommend the product with the addition of their remineralization kit. Worked wonders for my ex's gum disease in combination with this tooth powder.
