ProDentim is one of the most searched oral health supplements online, and most of the content about it is either uncritically positive affiliate content or dismissively negative skeptic content. Neither is particularly useful for someone trying to decide whether it is worth trying. Here is what the label lists and what published research says about each component. The maker’s website text and its label disagree in places, so we follow the label.
Lactobacillus reuteri
L. reuteri is one of the probiotic components on ProDentim’s label. The label lists the probiotic blend as 20 mg (3.5 billion CFU at the time of manufacture) without per-strain amounts, and it does not say which L. reuteri strain is used. Published studies of particular L. reuteri strains in the mouth are small and their results are mixed, and we found no published trial of ProDentim itself. Verdict: a component with some research behind the species, but not shown for this product.
Lactobacillus paracasei
Research on L. paracasei in the mouth is limited. Some laboratory work has looked at its effect on Candida, but we did not verify clinical evidence for oral health. Verdict: limited evidence for oral use.
Bifidobacterium lactis BL-04
BL-04 is mainly studied for gut and respiratory health. We did not find oral-health trials of this strain, so its role in an oral product is indirect. Verdict: a recognized strain, but not shown for oral health.
Streptococcus salivarius (strain not named)
The label lists Streptococcus salivarius at 20 mg without naming a strain. Some marketing pages name specific strains, but the label does not, so we cannot say which one is in the product. Verdict: unclear, because the strain is not identified.
Inulin (prebiotic fiber)
Inulin (100 mg per tablet on the label) is a prebiotic fiber, meaning a food source for some bacteria. Its inclusion alongside probiotics is a common formulation choice. Verdict: a standard addition.
Other ingredients and a label discrepancy
The label’s other ingredients are tricalcium phosphate, microcrystalline cellulose, natural strawberry flavor and peppermint essential oil. The maker’s website text also mentions malic acid, which does not appear on the label we read, so check the current label if that matters to you.
Overall assessment
The label lists four probiotic components, inulin and flavorings, with a combined 3.5 billion CFU and no per-strain amounts. Some of the species have small bodies of research, mostly on specific strains and products, but we found no published trial of ProDentim itself, and the unnamed S. salivarius strain makes comparison harder. The maker states a 60-day refund policy with conditions (all bottles must be returned at your own cost). Probiotics are not a substitute for brushing, cleaning between your teeth or dental care; talk to your dentist before starting one. Our supplement comparison places ProDentim alongside GumAktiv, ProvaDent, DentiCore and Dentavim, and our full ProDentim review covers price and refund details.
