When it comes to oral health, we’re all familiar with brushing, flossing, and regular dental check-ups. But recent research is revealing that our microbiome—the collection of trillions of bacteria and other microbes living in our bodies—may play an important role in keeping our mouths healthy. In particular, “postbiotics,” a lesser-known but very exciting area of microbiome research, are emerging as a new tool in supporting oral health. Let’s dive into what postbiotics are, their benefits for your mouth, and how they could change the way we approach oral hygiene.
What Are Postbiotics?
To understand postbiotics, it helps to first know a bit about probiotics and prebiotics:
- Probiotics are live beneficial bacteria that promote a balanced microbiome.
- Prebiotics are the “food” these bacteria consume, supporting their growth and activity.
Postbiotics, in contrast, are the bioactive compounds produced by probiotics as they break down prebiotics in the body. These compounds can include short-chain fatty acids, enzymes, proteins, peptides, and other beneficial metabolites that, rather than requiring live bacteria, deliver their effects directly to the body. Unlike probiotics, which can be sensitive to heat and acidity, postbiotics are stable and can be more easily integrated into a variety of health products.
In recent years, postbiotics have gained attention for their immune-boosting, anti-inflammatory, and antimicrobial properties—and now, they’re showing promise in supporting oral health too.
How Postbiotics Benefit Oral Health
Research into postbiotics and oral health is still developing, but the findings so far indicate that postbiotics can have several benefits for maintaining a healthy mouth. Here’s how they could make a difference:
1. Reducing Harmful Bacteria
The mouth is home to both helpful and harmful bacteria. When harmful bacteria (like Streptococcus mutans, a primary cause of cavities) grow out of control, they create plaque and acids that lead to tooth decay and gum disease. Postbiotics contain antimicrobial properties that help keep the harmful bacteria in check without disrupting the balance of the beneficial bacteria. This selective inhibition can reduce the risk of cavities and gum disease while promoting overall microbial balance.
2. Supporting the Body’s Natural Defence Mechanisms
Some postbiotics, particularly certain peptides and enzymes, play a role in supporting the body’s immune responses. In the context of oral health, this can mean reducing inflammation in the gums, which is often linked to conditions like gingivitis and periodontitis. By minimising inflammation, postbiotics help create a healthier environment in the mouth and reduce the potential for gum disease.
3. Strengthening the Oral Barrier Against Pathogens
The mucosal lining in our mouths serves as a barrier to harmful pathogens, helping to keep them out of the bloodstream and the broader body system. Postbiotics have been found to reinforce the mucosal barrier by encouraging the production of protective proteins. This strengthens the mouth’s first line of defence and limits the entry of harmful microbes, protecting both oral and overall health.
4. Neutralising Oral Acidity
Postbiotics can also help in balancing the pH levels in the mouth. Oral acidity, which is often a result of consuming sugars or acidic foods, can erode tooth enamel, leading to increased sensitivity, decay, and discoloration. Certain postbiotic compounds, particularly short-chain fatty acids, help in neutralising acids in the mouth, maintaining a healthy pH that prevents the demineralisation of teeth.
Current Research on Postbiotics for Oral Health
While research on postbiotics is relatively new and carried out in recent years, studies are already demonstrating their potential for improving oral health. In a 2021 study, scientists found that certain postbiotic compounds could inhibit the growth of harmful bacteria linked to tooth decay. Another study published in 2022 showed that postbiotics could help reduce inflammation in gum tissue, suggesting potential in the management of periodontal disease.
How to Incorporate Postbiotics into Your Oral Health Routine
As postbiotics continue to grow in popularity, here are some tips for using them as part of your daily oral care:
1. Look for Oral Care Products with Postbiotics: Some specialty toothpastes and mouthwashes already contain postbiotic ingredients.
2. Postbiotic Supplements: Postbiotic supplements like ours at Oh My Gob, may offer benefits for the mouth and beyond. We use ingredients that have been studied for their antimicrobial and anti-inflammatory properties.
3. Eat a Microbiome-Friendly Diet: Foods high in fiber, polyphenols, and certain fermented products can help foster a healthy microbiome. Eating a balanced diet that supports beneficial bacteria may also support the production of postbiotics naturally in the body.
4. Maintain Your Usual Oral Hygiene Routine: Postbiotics aren’t a replacement for brushing and flossing, which remain essential to preventing plaque buildup and maintaining a clean mouth. Instead, postbiotics should be considered a supportive addition to your routine, adding an extra layer of defence against harmful bacteria and inflammation.
The Future of Oral Health with Postbiotics
The inclusion of postbiotics in oral health is a promising step toward a more holistic and microbiome-centered approach to dental care. As science continues to explore the potential of these powerful compounds, we may soon see postbiotics as a key ingredient in mainstream oral care products. For now, being mindful of the benefits of postbiotics and incorporating them where possible, like using Oh My Gob supplements daily, can offer an extra layer of protection for your teeth and gums.
Incorporating postbiotics into your oral health routine might be a small step, but it could make a big difference in maintaining a healthy, balanced mouth—and ultimately, a brighter and fresher smile.
