ProDentim wins overall for its higher CFU count (3.5B vs 2.5B) and stronger individual probiotic strain research. ProvaDent wins on value — it's more affordable and includes the unique BioFresh Clean Complex (cranberry, neem, tea tree) that ProDentim lacks. Both are quality oral probiotics. Your choice depends on whether you prioritize potency or value.
ProDentim and ProvaDent are the two most popular oral probiotic supplements on the market, and they're frequently compared by shoppers trying to decide between them. Both use dissolvable tablets, both target the oral microbiome, and both come with 60-day guarantees.
So what actually separates them? We put both products through a detailed head-to-head comparison across six categories that matter most.
How We Compared
We evaluated ProDentim and ProvaDent across six categories:
- Probiotic Strains — Which strains, and how well are they researched for oral health?
- CFU Count — How many colony-forming units per serving?
- Additional Ingredients — What else is in the formula beyond probiotics?
- Delivery Format — How well does each product colonize the oral cavity?
- Pricing & Value — Cost per day, bulk discounts, guarantee terms
- Clinical Evidence — How strong is the research behind the specific formulation?

Category 1: Probiotic Strains
ProDentim's Strains
ProDentim features three core probiotic strains:
- Lactobacillus reuteri — The most well-studied oral probiotic strain. A systematic review in the Journal of Clinical Periodontology (2020) found it significantly reduced bleeding on probing and pocket depth in periodontitis patients. Also produces reuterin, a natural antimicrobial compound.
- Lactobacillus paracasei — Demonstrated ability to inhibit periodontal pathogens, particularly P. gingivalis. Supports gum health and sinus function.
- B.lactis BL-04 — Supports immune health, which benefits the oral immune system's ability to manage pathogenic bacteria.
ProvaDent's Strains
ProvaDent uses the same three core strains — L. reuteri, L. paracasei, and B.lactis BL-04. The strain selection is functionally identical.
Verdict: Tie on Strains
Both products use the same core probiotic strains, so the strain selection itself doesn't differentiate them. The difference lies in the amount (CFU count) and supporting ingredients.
Category 2: CFU Count
ProDentim: 3.5 billion CFU per tablet ProvaDent: 2.5 billion CFU per tablet
ProDentim delivers 40% more colony-forming units per serving. More CFU generally means more bacteria available for oral colonization.
However, the relationship between CFU count and effectiveness isn't perfectly linear. A study in Beneficial Microbes (2018) found that strain specificity and viability matter more than raw CFU numbers. Above a certain threshold (generally 1-2 billion for oral applications), the marginal benefit of additional CFU decreases.
Both products exceed the research-supported minimum, but ProDentim's higher count provides a modest edge.
Verdict: ProDentim Wins
ProDentim's 3.5 billion CFU provides a meaningful advantage, though both products are above the effective threshold.
Category 3: Additional Ingredients
This is where the two products diverge most significantly.
ProDentim's Additional Ingredients
- Inulin — Prebiotic fiber that feeds the probiotic strains, supporting colonization
- Malic Acid — Found in strawberries; supports natural teeth whitening by reducing surface stains
- Tricalcium Phosphate — Mineral support for enamel remineralization
- Peppermint — Fresh breath and mild antibacterial properties
ProDentim's additions focus on enamel support (tricalcium phosphate), prebiotic support (inulin), and cosmetic appeal (malic acid whitening).
ProvaDent's Additional Ingredients
- Cranberry Extract — A-type proanthocyanidins inhibit S. mutans adhesion to tooth surfaces (Journal of Dental Research, 2015). Unique antibiofilm mechanism.
- Neem Oil Extract — Ayurvedic antimicrobial comparable to chlorhexidine for plaque and gingivitis reduction (Journal of Indian Society of Periodontology, 2016)
- Peppermint Oil — Antimicrobial against S. mutans and Candida albicans
- Tea Tree Oil — Documented to reduce gingival bleeding and plaque in gingivitis patients (Oral Diseases, 2014)
ProvaDent's BioFresh Complex takes a different approach — natural antimicrobial agents that create a hostile environment for pathogenic bacteria while the probiotics establish beneficial colonies.
Verdict: Depends on Your Priorities
If you want enamel support and prebiotic enhancement, ProDentim's additions are more relevant. If you want natural antimicrobial protection against plaque and biofilm, ProvaDent's BioFresh Complex is more interesting. Neither is objectively "better" — they serve different supplementary purposes.
Category 4: Delivery Format
Both ProDentim and ProvaDent use dissolvable tablets designed to be placed on the tongue and allowed to melt slowly. This is the correct delivery format for oral probiotics — it ensures the bacteria are deposited directly in the oral cavity rather than passing through the stomach to the gut.
Both manufacturers recommend taking the tablet after brushing and avoiding mouthwash for 30 minutes afterward.
Verdict: Tie
Identical delivery format. Both products correctly use the dissolvable tablet approach rather than swallowed capsules.
Category 5: Pricing & Value
| | ProDentim | ProvaDent | |---|---|---| | 1 bottle (30 days) | $69 ($2.30/day) | $59 ($1.97/day) | | 3 bottles (90 days) | $177 ($1.97/day) | $147 ($1.63/day) | | 6 bottles (180 days) | $294 ($1.63/day) | $234 ($1.30/day) | | Guarantee | 60 days | 60 days | | Shipping | Free | Free |
ProvaDent is consistently $10 per bottle cheaper at every quantity tier. Over a 6-month supply, that's a $60 savings.
Verdict: ProvaDent Wins
ProvaDent is 14-15% cheaper across all quantity options. Both offer the same guarantee terms.
Category 6: Clinical Evidence
Neither product has undergone independent clinical trials as a complete formulation — this is typical for dietary supplements. The evidence base rests on the individual ingredients.
ProDentim's edge: The L. reuteri research is the strongest of any oral probiotic ingredient, and ProDentim delivers it at a higher CFU count. Tricalcium phosphate for enamel remineralization is well-established.
ProvaDent's edge: The cranberry extract research for inhibiting S. mutans adhesion is compelling and unique among oral probiotic products. Neem's comparison to chlorhexidine in peer-reviewed studies adds credibility.
Verdict: Slight Edge to ProDentim
ProDentim's higher CFU count of the most well-studied oral probiotic strain (L. reuteri) gives it a slight evidence advantage. However, ProvaDent's BioFresh ingredients also have genuine research support.
The Bottom Line: Which Should You Choose?
Choose ProDentim if:
- You want the highest CFU count and maximum probiotic potency
- Enamel support (tricalcium phosphate) is important to you
- You want the slight whitening benefit of malic acid
- Budget is not your primary concern
- You prefer the most research-backed option
Choose ProvaDent if:
- Value matters — you want effective oral probiotics at a lower price
- The BioFresh Complex appeals to you (cranberry, neem, tea tree, peppermint oil)
- You're interested in the antimicrobial/antibiofilm approach alongside probiotics
- You plan to use the product long-term and want to minimize cost
- You've tried ProDentim and want to explore alternatives
Our Recommendation
For most people, ProDentim is the better first choice — its higher CFU count and the strongest research backing on L. reuteri make it the safer bet. It's our #1 rated oral probiotic for a reason.
However, ProvaDent is not far behind and offers genuine advantages: the BioFresh Complex is unique and scientifically interesting, and the $60 savings over 6 months is meaningful. If ProDentim's price is a barrier, ProvaDent delivers 85-90% of the benefit at a notably lower cost.
Some users even alternate between the two — using ProDentim for 3 months, then switching to ProvaDent for 3 months — to benefit from both formulations' unique ingredients. There's no research specifically supporting this strategy, but it's logical.
