What Is ProDentim?
ProDentim is an oral probiotic supplement designed to provide several probiotic strains in a single chewable/dissolvable product.
The manufacturer’s current information lists probiotic strains including Lactobacillus paracasei, Lactobacillus reuteri and Bifidobacterium lactis BL-04. It also lists additional ingredients such as inulin, malic acid, tricalcium phosphate and peppermint.

The idea behind an oral probiotic is to introduce beneficial microorganisms as part of an overall oral-care routine. However, an oral probiotic should not replace brushing, interdental cleaning or regular dental visits.
Good oral hygiene involves more than brushing alone. Cleaning between the teeth is also an important part of a daily oral-care routine. If you’re looking for a convenient option, you can check the Oral-B Glide Deep Clean Dental Floss on Amazon.
The Core Difference: Broad vs. Focused
The main difference between these products is their probiotic approach.
ProDentim: Multi-Strain Formula
ProDentim uses multiple probiotic strains rather than focusing on just one strain.
Its published ingredient information includes:
- Lactobacillus paracasei
- Lactobacillus reuteri
- Bifidobacterium lactis BL-04
This type of formulation may appeal to people who prefer a broader combination of probiotic strains.
BioGaia Prodentis: Focused Formula
BioGaia Prodentis focuses on two specific L. reuteri strains:
- DSM 17938
- ATCC PTA 5289
BioGaia has conducted and published research relating to these specific strains.
That doesn’t automatically mean one approach is better than the other. More strains do not necessarily mean better results, and research on one probiotic strain should not automatically be assumed to apply to another.
What Is BioGaia Prodentis?
BioGaia Prodentis is an oral probiotic product that uses two specific strains of Lactobacillus reuteri:
- L. reuteri DSM 17938
- L. reuteri ATCC PTA 5289
BioGaia’s product information describes Prodentis as a lozenge designed to dissolve in the mouth.
The company’s information also provides research relating to these specific probiotic strains.
This makes BioGaia Prodentis different from a broader multi-strain formula like ProDentim.

The exact ingredients can vary by product version and market, so check the label of the product you’re purchasing.
Which Product Has More Probiotic Strains?
If you’re comparing only the number of listed probiotic strains, ProDentim takes the broader multi-strain approach.
BioGaia Prodentis focuses on two specific L. reuteri strains.
However, the number of strains alone isn’t enough to determine which product is better.
When comparing probiotics, it’s useful to consider:
- The exact strains
- The amount provided
- The delivery format
- The research behind the specific strains
- The rest of the formulation
- Your own preferences and needs
Who Might Prefer BioGaia Prodentis?
BioGaia Prodentis may appeal to people who:
- Prefer a focused probiotic formulation
- Specifically want L. reuteri strains
- Prefer a dissolving lozenge
- Value research associated with specific probiotic strains
- Want a product that is available through established retail channels in their market
If your preference is for a targeted formulation rather than a broader multi-strain product, BioGaia Prodentis may be worth considering.
Who Might Prefer ProDentim?
ProDentim may appeal to people who:
- Prefer a multi-strain formula
- Want several probiotic strains in one product
- Prefer a chewable/dissolvable format
- Want to purchase primarily online
- Like the idea of a formula that also includes ingredients such as inulin
Again, these are product preferences, not a claim that ProDentim will produce better results for everyone.
Can You Take Both ProDentim and BioGaia Prodentis?
Taking two different probiotic products together isn’t necessarily better than choosing one.
If you’re thinking about combining supplements, consider the total ingredients and follow the directions for each product.
It’s especially important to speak with a healthcare professional before combining supplements if you take medication, have a medical condition, are pregnant or breastfeeding, or have other health concerns.
What About the Price?
ProDentim pricing can vary depending on the package, promotions and current offers. [See our detailed pricing breakdown] for more information.
BioGaia Prodentis pricing can also vary depending on the country, retailer and package size.
Because prices change frequently, it’s better to check the current product page rather than relying on an old price mentioned in a comparison article.
Tip: Don’t choose an oral probiotic based only on price. Compare the formulation, serving size, ingredients, convenience and available research as well.
Where Can You Buy ProDentim?
If you’re interested in ProDentim, it’s important to check the current purchasing information and make sure you’re using the appropriate official sales channel.
[See our full guide on where to buy ProDentim] before placing an order.
Be cautious when purchasing health supplements from unknown websites, especially if the seller makes unusually strong health claims or offers a price that seems too good to be true.
ProDentim vs BioGaia Prodentis: Which One Should You Choose?
There’s no universal winner.
Your choice may come down to what you value most.
Choose ProDentim if you prefer:
- A broader multi-strain formula
- Multiple probiotic strains
- A chewable/dissolvable format
- An online purchasing experience
- A formula containing additional ingredients such as inulin
Choose BioGaia Prodentis if you prefer:
- A focused two-strain formula
- Specific L. reuteri strains
- A dissolving lozenge
- Research associated with those specific strains
- Retail availability where offered
Ultimately, the best choice depends on your personal preferences and circumstances
Are Oral Probiotics a Replacement for Brushing?
No.
This is an important point regardless of which product you choose.
An oral probiotic should complement a regular oral-health routine that includes:
- Brushing twice daily
- Cleaning between your teeth
- Regular dental checkups
- A balanced diet
- Following your dentist’s recommendations
If you’re experiencing persistent tooth pain, bleeding gums, swelling, loose teeth or other concerning symptoms, speak with a dental professional rather than relying on a supplement.
How Long Does an Oral Probiotic Take to Work?
There isn’t one guaranteed timeframe for every oral probiotic.
Research can differ depending on the probiotic strain, formulation, dosage and outcome being studied. Individual experiences can also vary.
Rather than expecting an immediate change, follow the product’s directions consistently and maintain good oral hygiene.
Are ProDentim and BioGaia Prodentis FDA Approved?
This is an important distinction when researching dietary supplements.
The FDA does not approve dietary supplements for safety and effectiveness before they are marketed in the same way that it approves drugs.
Therefore, be cautious when you see a dietary supplement described simply as “FDA approved.”
The FDA also advises consumers to discuss dietary supplements with a healthcare professional because supplements can interact with medications or have other risks.
