There is another probiotic-based prophylactic supplement to protect teeth and gums called PurDentix. It has four probiotic strains: Lactobacillus Salivarius, Lactobacillus paracasei, Bifidobacterium lactus (B1-04), and Lactobacillus reuterei plus calcium triphosphate. This is a subset of ingredients in ProDentim, which you have given a very high rating for promoting and maintaining dental health. How would you rank the relative effectiveness of PurDentix compared to ProDentim and why?

We see the ProDentim as being superior and that is because of the extra ingredients it offers compared to the PurDentix supplement you have seen discussed recently. Both are effective in making beneficial improvements in oral hygiene and oral health and keeping the teeth and gums protected from degradation. So we would say the PurDentix is nearly as good but does not outrank the ProDentim with regard to prophylactic care as well as restoration possible with its combination of ingredients.
