Dr. Christopher just suggested taking a wet tooth brush and a little powder to brush the teeth and then swallow the herbs and no need to spit out like toxic tooth paste.
For our kids we mix it with sorghum molasses. A tablespoon of sorghum daily as little children, is suppose to avoid all dental decay. I have seen Amish familys that have never brushed their teethe and have zero cavities and pure white teethe. 99.9% of Amish have horrible teethe, but a few who make sorghum and consume allot of it never brush and have perfect teethe and bones.
