Maintaining a healthy mouth goes far beyond brushing and flossing. As more people turn to natural wellness solutions, Mānuka honey has gained attention not only for immune support and digestive health but also for its potential benefits in oral care. With its unique antibacterial properties, Mānuka honey may support gum health, reduce plaque-causing bacteria, and even help soothe common conditions such as gingivitis and mouth ulcers.
This article will explore what the science says about Mānuka honey and oral health, how it works, and how it might be safely incorporated into a daily routine. Please note that while Mānuka honey may complement oral hygiene practices, it should not replace advice or treatment from a dental professional.
What Is Mānuka Honey?
Mānuka honey is a type of monofloral honey produced by bees that forage on the flowers of the Leptospermum scoparium plant, native to New Zealand. It is distinct from regular honey due to its naturally occurring compounds that give it significant antibacterial activity.
One of the most important of these compounds is methylglyoxal (MGO). MGO is largely responsible for Mānuka honey's antimicrobial strength. Its presence is measured and labelled by concentration (e.g. MGO 100+, MGO 525+, MGO 850+), which helps users select a product suited to their needs.
How Can Mānuka Honey Support Oral Health?
Mānuka honey’s application to oral care lies primarily in its ability to inhibit harmful bacteria, reduce inflammation, and promote tissue healing. Let’s explore these functions in more detail.
1. Antibacterial Action Against Oral Pathogens
Mānuka honey has been shown to inhibit the growth of harmful bacteria commonly associated with tooth decay and gum disease. Research has demonstrated that Mānuka honey can be effective against:
-
Streptococcus mutans: A primary contributor to dental plaque and cavities
-
Porphyromonas gingivalis: Strongly associated with periodontitis (gum disease)
-
Fusobacterium nucleatum: A bacteria that contributes to bad breath and inflammation
In one in vitro study, Mānuka honey was found to reduce bacterial growth in dental plaque biofilm. While more clinical research is needed, these findings suggest that Mānuka honey may help control the bacterial load in the mouth.
2. Reducing Plaque Formation
Plaque is a sticky film of bacteria that forms on teeth, leading to tartar build-up and eventually tooth decay or gum problems. Regular honey contains sugars that can feed plaque-forming bacteria, but Mānuka honey behaves differently. Thanks to its high MGO content and low pH, it creates an environment that is less favourable for bacterial growth, potentially reducing plaque build-up when used correctly.
A small clinical trial showed that chewing Mānuka honey–based lozenges resulted in a significant reduction in plaque levels without increasing tooth decay risk. This has led to increased interest in Mānuka-infused oral care products such as mouthwashes and pastilles.
3. Anti-Inflammatory Effects on Gums
Inflamed gums are a hallmark of gingivitis and periodontitis. Mānuka honey’s anti-inflammatory properties can help soothe gum tissue. These properties are linked to compounds such as flavonoids and phenolic acids found naturally in the honey.
By calming inflammation, Mānuka honey may support healing in early-stage gum disease, particularly when applied to affected areas or used in a diluted rinse. It is not a substitute for scaling or professional treatment but may help alleviate irritation and bleeding between dental visits.
4. Helping Mouth Ulcers and Minor Wounds Heal
Many people experience ulcers, cuts, or irritation in the mouth due to stress, braces, or minor injuries. Mānuka honey’s tissue-healing properties have been well documented in wound care. When applied topically, it may form a protective barrier, reduce bacterial contamination, and speed up the healing process of soft oral tissues.
Some clinical settings already use medical-grade honey to treat burns and wounds, which supports its potential for oral mucosal healing. In addition, Mānuka honey’s texture allows it to adhere briefly to ulcerated areas, delivering prolonged exposure to its bioactive compounds.
Safe Use of Mānuka Honey for Oral Health
While Mānuka honey shows promise as a supportive oral care ingredient, it must be used appropriately. Here are some tips and considerations:
1. Use Certified MGO Mānuka Honey
Choose honey that has been tested for MGO content and is packaged by a reputable brand. ManukaLab’s products are independently tested and clearly labelled, offering transparency and reliability in what you’re using on or in your body.
2. Avoid Brushing Immediately After Honey Use
While Mānuka honey has antimicrobial benefits, it still contains natural sugars. Avoid brushing immediately after use to prevent enamel erosion. Instead, rinse with water and wait at least 30 minutes.
3. Try It in a Rinse or Mouth Soothing Paste
You can dilute a small amount of Mānuka honey in warm (not hot) water to create a soothing rinse. This may help relieve mild gum inflammation or irritation. Alternatively, applying a dab directly to mouth ulcers or sore spots with a clean cotton bud may offer relief.
4. Consult Your Dentist for Persistent Issues
If you experience ongoing symptoms such as bleeding gums, tooth sensitivity, or frequent ulcers, seek advice from a dental professional. Mānuka honey may complement oral hygiene practices but should not be used as a standalone treatment for dental conditions.
Is It Backed by Research?
Several studies have evaluated Mānuka honey’s effectiveness against oral bacteria and inflammation:
Antibacterial Action Against Oral Pathogens
A study published in the Journal of Periodontology assessed the antibacterial activity of medical-grade Mānuka honey against dental plaque-associated bacteria. The research demonstrated that Mānuka honey exhibits antimicrobial properties effective against pathogens such as Streptococcus mutans and Porphyromonas gingivalis, which are associated with dental plaque and periodontal diseases.
Reduction of Plaque and Gingival Inflammation
A pilot study investigated the effects of Mānuka honey on dental plaque and gingivitis. Participants who chewed or sucked on a Mānuka honey product three times daily for 21 days experienced significant reductions in plaque accumulation and gingival bleeding compared to a control group using sugarless chewing gum.
Disruption of Bacterial Biofilms
Research has shown that Mānuka honey can disrupt biofilm formation by oral bacteria. In vitro studies demonstrated that Mānuka honey inhibits the growth and adherence of bacteria such as Streptococcus mutans, suggesting its potential role in reducing oral pathogens found in dental plaque.
Although the current body of evidence is still developing, early findings are promising. Researchers agree that further controlled clinical trials are needed, particularly to understand long-term effects and the ideal dosage for oral care use.
Final Thoughts
Mānuka honey’s naturally occurring antibacterial, anti-inflammatory, and tissue-repairing properties make it a compelling option for supporting oral health. Whether you are looking to reduce plaque, soothe gum irritation, or help mouth ulcers heal, Mānuka honey may offer gentle, natural assistance when used responsibly.
