I am having a hard time using the Tooth/Gum Herbal Powder, I'm not having any problems brushing my teeth with it, my problem is trying to get it to stay around my tooth, I have a front tooth where the gum has receded and the tooth is a little loose, so at night I try to pack the Tooth/Gum Herbal Powder around that tooth, but I can't get the powder to stay in place, must it be packed around the tooth? Or is it enough that the powder is in the mouth?
