This is an all natural tooth powder with no preservatives, flow agents, propylene glycol, titanium dioxide, SLS, or other harmful chemicals or synthetics to keep it at a spreadable consistency, extend the shelf life, and in turn, make it less healthy. 
I make all my products in small batches by hand and I never cut corners on top quality ingredients.  
Just dip your moist toothbrush into the powder and brush as you normally would.  I don’t fully rinse my mouth right away to allow the minerals more time on my teeth after brushing. This is safe for kids and not harmful if swallowed.  
Minerals occur naturally in saliva and get absorbed into the tooth enamel. The acids in food demineralize teeth by stripping out these minerals, which can leave teeth vulnerable to cavities. Remineralizing toothpaste is specially formulated to return minerals to tooth enamel to help prevent tooth damage.
Remineralizing toothpaste contains active ingredients that strengthen teeth and prevent white spot lesions from forming. These ingredients also help to repair existing white spots in tooth enamel.
Remineralizing tooth powder serves many functions, including:
repairing acid-weakened tooth enamel
protecting teeth from acid erosion
strengthening tooth enamel
preventing cavities
keeping teeth white without abrasive ingredients
stopping acid-producing bacteria from forming and sticking to teeth
How does remineralizing toothpaste work?
Remineralizing toothpaste works by strengthening each tooth’s outer layer and boosting the absorption of minerals deep into tooth enamel, where existing damage can be repaired. This process is known as remineralization.
The active ingredients in remineralizing toothpaste include calcium, potassium, phosphorus,  And other important minerals. These minerals are essential for keeping teeth strong and white. 
My formula contains no harmful ingredients such as fluoride, SLS, baking soda, or synthetically produced hydroxyapatite. 
Xylitol kills bacteria that cause tonsil stones, bad breath and cavities. Sage kills bacteria and freshens breath. 
With regular use you will see a noticeable change in your teeth and it’s possible to reverse tooth decay.  
The acid in food and drinks can weaken your teeth over time. Remineralizing toothpaste strengthens tooth enamel, making teeth less prone to erosion, discoloration, and cavities.
