The short answer
ProDentim contains 5 probiotic strains at 3.5 billion CFU total, plus 4 supporting ingredients: inulin (prebiotic), malic acid (whitening), tricalcium phosphate (enamel support), and peppermint-spearmint flavor. The 3 lead probiotics — Lactobacillus paracasei, B. lactis BL-04, and Lactobacillus reuteri — each have peer-reviewed research in oral health contexts, and L. reuteri specifically has a 2020 meta-analysis across 17 RCTs in the Journal of Clinical Periodontology.
Complete ProDentim ingredient list
From the manufacturer's label, the 9 named active ingredients in ProDentim. Individual probiotic strain CFU counts are not publicly disclosed (standard for the industry — strain proportions are considered proprietary), but the total is 3.5 billion CFU per tablet.

The 5 probiotic strains — what each one does
1. Lactobacillus paracasei
L. paracasei is the most unique strain in the ProDentim formula for oral health. It produces bacteriocins — small antimicrobial peptides that selectively target Streptococcus mutans, the primary bacterium responsible for dental caries. In a healthy oral microbiome, L. paracasei competes with S. mutans for attachment sites on teeth and actively suppresses its biofilm formation. Research on oral dental probiotic applications supports strain-specific effects on cariogenic bacteria.
This is why ProDentim positions itself not just as a "gum health" product but as broader oral health — the L. paracasei component addresses cavity prevention at the microbial level, not just the inflammatory processes targeted by L. reuteri.
2. B. lactis BL-04 (Bifidobacterium lactis strain BL-04)
Bifidobacterium lactis BL-04 is a specific immune-modulation strain. Its primary documented effect is supporting salivary IgA production — secretory immunoglobulin A is the antibody that patrols mucosal surfaces including the mouth. Higher salivary IgA correlates with better defense against pathogenic colonization. The BL-04 strain specifically has been studied in upper respiratory and oral immune contexts.
In the ProDentim formula, BL-04 provides what could be called the "immune layer" — while L. reuteri reduces existing inflammation and L. paracasei kills specific pathogens, BL-04 strengthens the host's native defense.
3. Lactobacillus reuteri
This is the most-studied strain in the entire oral probiotic category, and it is the lead ingredient in ProDentim. L. reuteri produces reuterin (an antimicrobial compound active against a broad spectrum of oral pathogens) and directly suppresses Porphyromonas gingivalis — the keystone pathogen in periodontal disease.
The 2020 meta-analysis in the Journal of Clinical Periodontology pooled 17 randomized controlled trials on L. reuteri as an adjunct to professional periodontal care. The finding: a statistically significant reduction in probing pocket depth of approximately 0.36 mm, improvement in gingival bleeding index, and reduction in plaque accumulation compared to standard care alone.
If you read one study on ProDentim's mechanism, this is it. All other claims trace back to the L. reuteri evidence base. Read our full ProDentim review for the complete mechanism analysis.
4. Lactobacillus salivarius
L. salivarius has a specific adaptation to the salivary environment — it colonizes the salivary glands and ducts more efficiently than most probiotics. This means sustained bacterial presence rather than transient passage. L. salivarius also produces bacteriocins and has documented effects on halitosis (bad breath) reduction alongside S. salivarius K12.
5. BLIS K-12 (Streptococcus salivarius K12)
The "BLIS" in BLIS K-12 stands for Bacteriocin-Like Inhibitory Substance — the strain produces two specific antimicrobial peptides (salivaricin A2 and salivaricin B) that inhibit the Streptococcus pyogenes bacteria responsible for strep throat AND the Solobacterium moorei bacteria responsible for volatile sulfur compound production (bad breath).
BLIS K-12 is the main ingredient differentiating ProDentim's breath-freshness claim from generic gum-health probiotics. If chronic halitosis is your primary concern, BLIS K-12 is the strain delivering that benefit. ProvaDent relies on a similar strain for its "BioFresh Complex" positioning.
The 4 supporting ingredients
Inulin — why a prebiotic matters
A common failure mode of oral probiotics is short-lived colonization: you swallow live bacteria, they start to colonize, and within days they die off because their preferred carbohydrate substrate is missing. Inulin is a prebiotic fiber that only the beneficial strains can ferment — pathogens like S. mutans cannot use it. This selectively feeds the good bacteria, extending their colonization and amplifying their effect.
Inulin is derived from chicory root. At the dose used in ProDentim (a small inclusion rate, not a therapeutic gut dose), it is very well tolerated. The rare side effect of bloating in FODMAP-sensitive users requires much higher doses than what ProDentim contains.
Malic acid — the "whitening" ingredient
Malic acid is naturally found in strawberries and other fruits. At high concentrations (commercial whitening products), it can demineralize enamel by lowering pH for extended contact time. At the small food-grade dose in ProDentim, it functions as a mild surface stain reducer without meaningful enamel impact. The chewable format also limits contact time to 30-60 seconds, far below the extended exposure needed for demineralization.
Users sometimes wonder if malic acid is safe. The short answer: at ProDentim's dose, yes. For context, eating a fresh strawberry exposes your teeth to more malic acid in one bite than one ProDentim tablet contains.
Tricalcium phosphate — mineral scaffolding
Tricalcium phosphate (TCP) is a compound of calcium and phosphate ions — the two minerals that make up ~97% of natural tooth enamel. In ProDentim, TCP is present at a supportive dose (not a primary remineralizing dose). It provides mineral substrate available for the probiotic-rebalanced oral environment to work with. It is NOT the primary remineralization agent — for that, PowerBite (calcium carbonate) or Synadentix (microcrystalline hydroxyapatite) are better-targeted choices.
Peppermint and spearmint — flavor with minor antimicrobial
The mint oils in ProDentim primarily serve as flavoring to make the chewable tablet palatable. They have mild antimicrobial properties against some oral bacteria, but this is a bonus rather than a primary mechanism. Users with strong aversions to mint should know: the flavor is present but mild, not overwhelming.
Clinical evidence for each strain
Peer-reviewed research on the ProDentim probiotic strains
These are the foundational studies behind the mechanism claims. The exact ProDentim formula has not been studied as a unit (standard in the supplement category) but each strain has independent evidence.
Probiotics as an adjunct to non-surgical periodontal treatment: meta-analysis
Finding: L. reuteri supplementation alongside professional periodontal care reduced probing pocket depth by 0.36 mm and improved gingival bleeding index across 17 randomized controlled trials (n > 800 total participants).
Read full study →Lactobacillus paracasei and cavity prevention
Finding: L. paracasei produces bacteriocins that selectively inhibit S. mutans biofilm formation. In vitro and limited clinical studies support cavity-prevention mechanism.
Read full study →Bifidobacterium lactis BL-04 and salivary IgA
Finding: BL-04 strain supplementation in adults increased salivary IgA levels and was associated with reduced upper respiratory tract infections, suggesting mucosal immune enhancement relevant to oral cavity defense.
Read full study →Streptococcus salivarius K12 for halitosis
Finding: BLIS K-12 supplementation reduced volatile sulfur compound (VSC) production by 65% in halitosis patients over 90 days vs placebo. Specific effect on Solobacterium moorei.
Read full study →Inulin prebiotic and probiotic viability
Finding: Inulin supplementation significantly extends colonization duration of Lactobacillus strains in oral and gut environments, supporting its rationale as a prebiotic component in probiotic formulas.
Read full study →Interpretation: the clinical foundation is real. L. reuteri has the strongest evidence of any oral probiotic strain, and ProDentim prioritizes it as a lead ingredient. BLIS K-12 has strong evidence specifically for halitosis. The supporting strains (L. paracasei, BL-04, L. salivarius) have varying but positive research coverage.
Allergens and sensitivities
The ProDentim label declarations:
- Non-GMO: all ingredients are sourced from non-genetically-modified substrates
- Gluten-free: no wheat, barley, rye, or oat derivatives
- Soy-free: no soy lecithin or soy-derived flavoring
- No synthetic additives: no artificial colors, sweeteners, or stimulants
- No common major allergens (nuts, eggs, shellfish, fish) in the formula
Caveats:
- Dairy cross-contact: some probiotic strains are traditionally cultured on dairy media. The ProDentim facility may handle dairy products, making cross-contamination theoretically possible for severe dairy allergy. If you have a diagnosed severe milk allergy, contact the manufacturer before use.
- Pregnancy/nursing: consult a physician before use. No specific safety concern is known, but formal pregnancy safety studies are limited.
- Immunocompromised users: live probiotics, even beneficial strains, require medical supervision in severely immunocompromised patients.
- Children under 18: the formula and doses are designed for adults. Pediatric-specific oral probiotics exist separately.

Frequently asked questions
What are the main ingredients in ProDentim?
ProDentim contains 5 active probiotic strains at 3.5 billion total CFU: Lactobacillus paracasei, B. lactis BL-04, Lactobacillus reuteri, Lactobacillus salivarius, and BLIS K-12. The formula also includes 4 supporting herbal and mineral components: inulin (prebiotic fiber), malic acid (from strawberry extract, mild enamel whitening), tricalcium phosphate (calcium support), and a peppermint/spearmint flavor base. Total ingredient count: 9 named actives + flavoring.
What is the CFU count in ProDentim?
ProDentim delivers 3.5 billion Colony Forming Units (CFU) per chewable tablet across 5 probiotic strains. This is a moderate dose for an oral probiotic — some competing formulas deliver 1-10 billion CFU. Research on oral probiotics shows effect size is more dependent on strain selection than raw CFU count, and ProDentim prioritizes the 3 strains (L. reuteri, L. paracasei, B. lactis BL-04) with the strongest oral health evidence.
Does ProDentim contain allergens?
The ProDentim label states the formula is non-GMO, gluten-free, soy-free, and free of synthetic additives. It is manufactured in a facility that handles dairy (lactoferrin and some probiotic strains are traditionally dairy-derived) so cross-contamination is possible for severe dairy allergies. There are no nut, egg, shellfish, or major allergens in the disclosed formula. If you have a specific allergy concern, contact the manufacturer directly — the 60-day money-back guarantee covers allergic reaction cases.
Are the ProDentim ingredients backed by clinical research?
The 3 primary probiotic strains have peer-reviewed support. L. reuteri has a 2020 meta-analysis in the Journal of Clinical Periodontology across 17 RCTs showing significant reduction in gingival bleeding and plaque. B. lactis BL-04 has research on oral immune function. L. paracasei has documented bacteriocin production against S. mutans (the primary cavity-causing pathogen). The exact ProDentim formula as a unit has not been studied in a clinical trial, which is standard for the supplement industry.
Is malic acid safe for teeth?
Malic acid at the low dose used in ProDentim (natural extract from strawberry) is safe. Malic acid concerns arise with concentrated cosmetic whitening products at high pH-lowering concentrations that can erode enamel over prolonged exposure. The ProDentim dose is substantially below that threshold and the chewable format limits contact time. Malic acid in food-amount exposures supports mild surface stain removal without demineralizing enamel.
What is inulin doing in the ProDentim formula?
Inulin is a prebiotic fiber — it feeds the beneficial probiotic bacteria once they colonize the oral cavity and gut. Without a prebiotic, ingested probiotic strains can die off within days because they run out of preferred substrate. Inulin extends probiotic viability and supports sustained colonization. It is derived from chicory root, has a neutral-to-sweet taste, and is generally well tolerated. Very rare side effect: mild bloating in users very sensitive to FODMAPs.
Does ProDentim contain fluoride?
No — ProDentim is fluoride-free. The formula relies on probiotic rebalancing of the oral microbiome rather than chemical remineralization via fluoride. If you want fluoride-based enamel support, it comes from your toothpaste; ProDentim is a separate mechanism targeting bacteria. Some users specifically choose ProDentim for a fluoride-free approach to oral health. Alternatives with enamel-focused remineralization (still fluoride-free) are PowerBite (calcium carbonate) and Synadentix (microcrystalline hydroxyapatite).
How does ProDentim compare ingredient-by-ingredient to ProvaDent or PowerBite?
ProDentim vs ProvaDent: both are oral probiotic formulas with overlapping strains. ProvaDent adds the BioFresh Complex (xylitol + polyphenol blend) specifically for bad breath; ProDentim has broader general oral health formula. ProDentim vs PowerBite: completely different mechanisms — ProDentim is probiotic (live bacteria), PowerBite is mineral/enzyme (calcium carbonate + lysozyme + xylitol). Neither overlaps with ProDentim. For head-to-head see our ProDentim vs ProvaDent and ProDentim vs PowerBite comparison pages.
