The powder is going to dissolve with the salvia, you should be able to pack a little between the gum and lip, no need to put on the tooth its self. The herbs tighten the flesh and then as they are swallowed they aid in cleansing the blood. It is the blood that causes most tooth problems. Blood that seeks to remove acids and the systems of eliminations (kidneys) are blocked, the blood will push these acids out of the teeth and ears, known to us as ear wax and tooth decay. Skin problems etc. are all signs that the diet is overwhelming the elimination organs. So instead of down and out, the waste comes up and out.
