1.5oz Remineralizing Mineral Tooth Powder - Refreshing Spearmint. This 1.5oz jar will last for approximately 50 brushes. Many conventional (and even some so-called natural) toothpaste brands contain harmful chemicals and poisons. Has it ever concerned you that there is a WARNING label on conventional toothpaste tubes? Not exactly something I want to see on a product I'm putting in mine and my kid's mouths multiple times a day. This recipe has NO fluoride, SLS, glycerin, or preservatives. It contains ZERO artificial ingredients or chemicals, and includes plenty of naturally occurring trace minerals to make your teeth strong, plus it leaves your mouth feeling clean and fresh. The ingredients in this tooth powder are not only non-toxic but they are alkalizing and great for your overall health! This means no need to worry about kid's swallowing the tooth powder. This product is SAFE for kids!
