Supporting Periodontal Health with a Clinically Studied Heat-Treated Postbiotic

Oral Microbiome Is Reshaping Oral Health Innovation

Consumers increasingly recognize that oral health is closely connected to whole-body wellness. While brushing, flossing, and mouthwash remain the foundation of daily oral care, growing awareness of the oral microbiome is expanding how consumers—and oral healthcare brands—think about supporting healthy gums and periodontal health.

For oral healthcare brands, this creates an opportunity to complement traditional oral care with science-backed solutions that support the oral microbiome and the body's natural defenses. Rather than focusing solely on cleansing the teeth and mouth, emerging approaches are targeting the biological processes that help maintain a healthy oral environment.

KT-11® is a proprietary, heat-treated Lactobacillus crispatus postbiotic developed to support periodontal health. Backed by human clinical research, KT-11® offers brands a differentiated approach to oral microbiome support that complements existing oral care portfolios.


The Opportunity: Expanding the Science of Oral Health

Consumers increasingly recognize that healthy gums and a balanced oral microbiome are important components of oral and overall wellness. As awareness of the oral microbiome grows, consumers are looking for complementary solutions that go beyond routine hygiene to provide additional periodontal and oral microbiome support.

KT-11® is a clinically studied, heat-treated Lactobacillus crispatus postbiotic that supports periodontal health through the gut-immune-oral axis, offering brands an innovative way to complement established oral care regimens with science-backed oral microbiome support.

This shift creates new opportunities for oral healthcare and dietary supplement brands to develop innovative oral delivery formats, including:

  • Lozenges
  • Chewable tablets
  • Chewing gum
  • Oral-dissolving tablets
  • Gummies
  • Oral powders
  • Other innovative oral delivery formats

Together, traditional oral care and microbiome-focused solutions can provide a more comprehensive approach to daily oral wellness.


How KT-11® Supports Oral Health

KT-11® supports periodontal health through the gut-immune-oral axis. Following ingestion, KT-11® interacts with the intestinal immune system, helping stimulate immune responses that extend to the oral cavity.

After ingestion, KT-11® activates intestinal immune cells that increase production of immunoglobulin A (IgA), one of the body's first lines of defense at mucosal surfaces. Research suggests these IgA-producing immune cells migrate to the salivary glands, where secreted IgA helps support the mouth's natural defenses against undesirable microorganisms.

KT-11® has also been shown to stimulate Porphyromonas gingivalis-specific IgG antibody responses, supporting immune recognition of one of the most well-known periodontal pathogens.

KT-11® mechanism of action: intake of KT-11 promotes IgA in intestinal immunity and then in saliva — reducing periodontal bacterium, increasing saliva, decreasing plaque and caring for gums — for prevention of periodontal disease; a Peyer's patch diagram shows IgA travelling to the mouth against P. gingivalis, and a chart shows IgA in saliva rising from 100 at week 0 to 121.7 two weeks later

Targeting Bacteria Associated with Periodontal Health

Among the many bacteria found in the oral microbiome, Porphyromonas gingivalis (P. gingivalis) is widely recognized as one of the primary pathogens associated with periodontal disease. Elevated levels of P. gingivalis have been linked with gum inflammation and the destruction of tissues supporting the teeth.

Human clinical research demonstrates KT-11® helps reduce the presence of P. gingivalis, supporting a healthier oral environment through immune-mediated mechanisms.


Human Clinical Evidence

KT-11® has been evaluated in a randomized, double-blind, placebo-controlled human clinical study involving 16 healthy adults who consumed 30 mg daily (approximately 12 billion heat-treated cells), as a meltable tablet for four weeks.

Researchers evaluated periodontal-associated bacteria alongside multiple oral health indicators. Their key clinical findings include:

Reduced Periodontal Pathogens

  • Significant reduction in P. gingivalis compared with placebo
  • Significant reduction in Treponema denticola (T. denticola) in saliva

Improved Oral Health Indicators

  • Reduced plaque scores
  • Reduced gingival redness
  • Reduced gingival swelling
  • Increased oral mucosal fluid scores

Preclinical Research Supports Periodontal Health

In a preclinical model, KT-11® supplementation for four weeks significantly reduced the presence of both P. gingivalis and T. denticola. Researchers also observed significantly less alveolar bone resorption, suggesting KT-11® may help support the structures that anchor teeth.

Why Formulators Prefer Heat-Treated Postbiotics

The Formulation Advantages of a Heat-Treated Postbiotic

As a heat-treated postbiotic, KT-11® offers important formulation and handling advantages compared with live probiotics.

Unlike live probiotics, KT-11® is heat-sterilized, making it significantly easier to formulate and manufacture.

Benefits include:

  • No refrigeration required
  • Excellent stability during storage and transport
  • No overage planning
  • Greater formulation flexibility
  • Compatible with a wide variety of food and supplement formulations

Less interaction with other formulation ingredients These attributes can simplify product development, manufacturing, transportation, and storage while providing formulators with a clinically studied postbiotic for oral health applications.


Versatile Oral Delivery Opportunities

KT-11® is well suited for oral delivery formats designed to provide contact within the oral cavity before swallowing. This creates opportunities for brands to incorporate postbiotic science into products that fit naturally alongside consumers' existing oral health routines.

Why KT-11® Is Different

Today's consumers are increasingly interested in oral health solutions that do more than clean the surface of the teeth. Growing awareness of the oral microbiome is creating demand for complementary approaches that support healthy gums and periodontal health as part of overall wellness.

KT-11® combines several important points of differentiation: a clinically studied heat-treated postbiotic, a distinctive gut-immune-oral mechanism, human research demonstrating reductions in key periodontal-associated bacteria, and the formulation advantages of a heat-treated ingredient.

For brands developing innovative oral health products, KT-11® offers a science-backed way to bring oral microbiome support into established or emerging oral care portfolios.
