What is BioGaia Prodentis Kids and who is it for?
BioGaia Prodentis Kids is a daily oral probiotic designed specifically for children aged 3 and up. Each delicious apple-flavoured lozenge contains 200 million CFU of two complementary L. reuteri strains that naturally colonize the oral cavity. This formulation provides nutritional support for maintaining a healthy oral microbiome—the community of beneficial bacteria that lives in your child’s mouth.
This product is ideal for children who are establishing oral hygiene habits, those with braces or orthodontic appliances that make thorough cleaning challenging, and kids who may benefit from additional support for their oral health alongside regular brushing and flossing. It’s also suitable for children who struggle with maintaining consistent oral hygiene routines.
Why choose oral probiotics for your child?
Your child’s mouth is home to billions of bacteria—both beneficial and less beneficial types. Just like the gut, the oral cavity has its own microbiome that plays a crucial role in dental health. Traditional oral hygiene focuses on removing bacteria through brushing and flossing, which is essential, but it doesn’t address the balance of the oral microbiome itself.
BioGaia Prodentis Kids takes a different approach by introducing beneficial bacteria that can colonize the oral cavity and support a more diverse microbial community. The two L. reuteri strains in this formula were specifically selected for their ability to adhere to oral surfaces and their complementary properties in supporting oral health.
How does this formula work differently?
Think of your child’s mouth like a garden—you can pull weeds (remove harmful bacteria through brushing), but you also need to plant flowers (introduce beneficial bacteria) to create a thriving, balanced ecosystem. That’s where oral probiotics come in.
Two strains working together: L. reuteri DSM 17938 and L. reuteri ATCC PTA 5289 work synergistically to support oral health. DSM 17938 was originally isolated from human breast milk, while ATCC PTA 5289 came from the oral cavity of a woman with excellent dental health despite poor oral hygiene—suggesting this strain has natural protective properties in the mouth.
How they colonize: When your child slowly dissolves the lozenge in their mouth, these probiotic strains are activated by saliva and begin to multiply. They form biofilms on oral surfaces including teeth, gums, and the tongue, where they can interact with the existing oral microbiome. Unlike transient bacteria that just pass through, these strains were selected for their ability to temporarily colonize and persist in the oral cavity.
The mechanism: Research suggests these L. reuteri strains can influence oral microbiome composition by competing for adhesion sites and nutrients with less beneficial bacteria. They may also support the body’s natural inflammatory response in the gums and contribute to maintaining normal pH levels in the mouth—an important factor since acidic conditions can affect tooth enamel.
Sweetened with tooth-friendly ingredients: The lozenges contain isomalt and xylitol rather than regular sugar. These sugar alcohols don’t feed cavity-causing bacteria and may actually support tooth mineralization. This means your child gets a tasty treat that doesn’t work against their dental health.

Common questions:
How is this different from regular probiotics? Most probiotic supplements are designed to support gut health and are formulated to survive stomach acid and reach the intestines. BioGaia Prodentis Kids is specifically designed for the oral cavity—it’s meant to be dissolved slowly in the mouth rather than swallowed. The strains in this formula were selected for their ability to adhere to oral surfaces and temporarily colonize the mouth, not the gut.
Will this replace brushing and flossing? Absolutely not. BioGaia Prodentis Kids is designed to complement, not replace, your child’s regular oral hygiene routine. Brushing twice daily and flossing remain essential for removing food particles, plaque, and bacteria from teeth and gums. Think of oral probiotics as an additional tool—like adding fertilizer to a garden you’re already watering and weeding.
My child has braces—is this suitable? Yes, this product can be particularly helpful for children with braces. Orthodontic appliances create additional surfaces where bacteria can accumulate and make thorough cleaning more challenging. The L. reuteri strains can help support oral microbiome balance even in hard-to-reach areas around brackets and wires.
How long does it take to see results? The L. reuteri strains begin colonizing the oral cavity as soon as the lozenge dissolves, but establishing a more balanced oral microbiome takes consistent daily use. Research studies have typically evaluated these strains over periods of several weeks to months. Remember that these beneficial bacteria are naturally expelled from the mouth after 2-3 weeks without continued supplementation, so daily use is important for ongoing support.
Does it need to be refrigerated? No, unlike many gut probiotics, BioGaia’s formulation is shelf-stable and doesn’t require refrigeration. This makes it convenient for travel, school, and keeping in your child’s daily routine.
My child doesn’t like taking tablets—will they take this? BioGaia Prodentis Kids is formulated as a lozenge with a pleasant apple flavor that most children enjoy. It’s designed to slowly dissolve in the mouth rather than being swallowed whole, making it easier and more appealing for kids than traditional tablets or capsules.
Key Features:

- Patented probiotic strains supported by 60+ clinical studies on oral health
- Apple-flavored lozenges designed for children aged 3 and up
- Sweetened with isomalt and xylitol—tooth-friendly sugar alternatives that support tooth mineralization
- Free from palm oil, gluten, milk, lactose, dairy, soy, preservatives, and added sugars
- Shelf-stable—no refrigeration required

Suggested Use:
Suitable for children aged 3 and up – 1 lozenge daily.
For best results, let the lozenge dissolve slowly in the mouth, preferably after brushing teeth in the evening. This allows the probiotic strains maximum contact time with oral surfaces before sleep—a period when saliva production naturally decreases and bacterial activity changes. The lozenge should not be chewed or swallowed whole.
