What Is ProDentim?
ProDentim is a chewable oral probiotic supplement designed to repopulate the mouth with beneficial bacteria. Each soft tablet contains 3.5 billion CFU from five distinct strains, targeting everything from cavity-causing bacteria to gum inflammation and ear, nose, and throat health. It’s one of the most-sold dental supplements on ClickBank and has accumulated thousands of verified customer reviews.
Manufactured in a GMP-certified, FDA-registered facility in the USA, ProDentim is free from artificial additives. Each bottle contains 30 tablets — a 30-day supply — priced between $49 and $69 depending on the package.

Key Ingredients Analysis
🦠 Lactobacillus Paracasei (part of 3.5B CFU blend)
One of the best-studied oral probiotics for dental health. L. paracasei has been shown to colonize the oral cavity temporarily and produce antimicrobial substances that inhibit S. mutans growth. It also supports the health of paranasal sinuses, which can contribute to chronic bad breath. Evidence level: 🟢 STRONG.
🦠 Lactobacillus Reuteri (part of 3.5B CFU blend)
L. reuteri produces two potent antimicrobial compounds: reuterin and reutericyclin. A meta-analysis of 12 randomized clinical trials published in Archives of Oral Biology found L. reuteri significantly reduced gingival bleeding and probing depth in periodontal patients. It also inhibits Porphyromonas gingivalis, the primary driver of periodontitis. Evidence level: 🟢 STRONG.
🦠 BLIS K-12 (Streptococcus salivarius K-12)
BLIS K-12 is the most studied oral probiotic for ear, nose, and throat (ENT) health. It produces bacteriocin-like inhibitory substances (BLIS) that directly kill harmful bacteria including group A streptococci. Clinical studies show it significantly reduces tonsillitis episodes and bad breath. Evidence level: 🟢 STRONG for ENT + bad breath.
🦠 BLIS M-18 (Streptococcus salivarius M-18)
BLIS M-18 is BLIS K-12’s sibling strain, but optimized for tooth and gum health rather than throat health. It has been shown to inhibit S. mutans and reduce plaque formation. A 2014 study found M-18 supplementation significantly reduced S. mutans counts in children over 3 months. Evidence level: 🟡 MODERATE — solid but fewer large-scale trials than K-12.
🌿 Inulin (Prebiotic)
Inulin is a prebiotic fiber that serves as fuel for beneficial bacteria. By feeding the probiotic strains, it helps them survive and colonize in the oral cavity longer. The pairing of probiotics with inulin is a best-practice formulation strategy. Evidence level: 🟡 MODERATE as oral prebiotic.
🍎 Malic Acid (from Strawberry)
Malic acid is naturally present in many fruits and is known for its mild whitening effect on tooth enamel by dissolving surface stains. Its inclusion in ProDentim adds a cosmetic benefit (whiter-looking teeth) to a primarily functional formula. Evidence level: 🟡 MODERATE — limited large-scale RCTs for teeth whitening specifically.
🦴 Tricalcium Phosphate
Tricalcium phosphate (TCP) is a bioavailable form of calcium phosphate that supports remineralization of tooth enamel when it comes into direct contact with the tooth surface. Used in clinical-grade toothpastes and dental products. Evidence level: 🟢 STRONG for remineralization.
🌿 Peppermint
Peppermint oil has well-documented antimicrobial properties against oral pathogens and contributes to fresh breath. It also has anti-inflammatory effects on gingival tissue. A minor but practical addition to the formula. Evidence level: 🟡 MODERATE.
Does ProDentim Match the Research? — Evidence Gap Analysis
| Aspect | Clinical Studies | ProDentim Formula | Match? |
|---|---|---|---|
| Total CFU count | 1–5B CFU effective range | 3.5B CFU | ✅ Yes |
| L. reuteri for gum disease | ~10⁸ CFU in periodontal studies | Included in blend | ✅ Yes |
| BLIS K-12 for bad breath/ENT | ~10⁹ CFU in ENT studies | Included in blend | ✅ Yes |
| BLIS M-18 for cavities | ~10⁸ CFU in dental studies | Included in blend | ✅ Yes |
| Individual strain CFU doses | Strain-specific dosing preferred | Proprietary blend (undisclosed per strain) | ⚠️ Unclear |
| Tricalcium phosphate (remineralization) | Used in clinical dental products | Included | ✅ Yes |
Verdict: ProDentim’s main strength is the combination of BLIS K-12 and M-18 strains — rarely found together in a single supplement. The main limitation is that individual strain CFU amounts aren’t disclosed, making it impossible to verify whether each strain reaches its clinically effective dose. That said, the overall 3.5B CFU total is within the effective range for oral probiotics.

Frequently Asked Questions
How do I take ProDentim?
Chew one tablet slowly in your mouth every morning. Do not swallow it whole — let it dissolve over 1–2 minutes so the probiotic strains can colonize the oral mucosa directly.
How long until I see results with ProDentim?
Users typically report fresher breath within 2–3 weeks. Noticeable improvements in gum sensitivity and overall oral comfort are usually seen at the 4–8 week mark with consistent daily use.
Can ProDentim whiten teeth?
The malic acid in ProDentim may help dissolve surface stains over time, giving a whitening effect. However, it’s not a tooth-whitening product — it’s an oral health supplement. Don’t expect dramatic whitening results; think of it as a mild, gradual stain removal effect.
Is ProDentim safe for long-term use?
The ingredients in ProDentim are generally recognized as safe for long-term use. Clinical studies on BLIS K-12 have followed participants for up to 12 months without significant adverse effects. Always consult your dentist if you have specific oral health conditions.
Does ProDentim replace brushing and flossing?
Absolutely not. ProDentim is a supplement that adds to your oral hygiene routine — it does not replace it. Think of it as support for the good bacteria in your mouth, working alongside (not instead of) daily brushing, flossing, and regular dental check-ups.
Our Final Verdict
ProDentim earns a 4.1/5 from our research team. It’s one of the few oral probiotic supplements that thoughtfully addresses multiple aspects of oral health simultaneously — bad breath, gum disease, enamel health, and ENT support — through a multi-strain approach. The inclusion of BLIS K-12 and M-18 together is genuinely rare and adds scientific value. The main drawback is the lack of per-strain CFU disclosure. The 60-day guarantee makes it a low-risk trial for anyone looking to improve their oral microbiome.
