The Role of Manuka Honey for Oral Health
Manuka honey is one of nature’s strongest healers and has served historically as a remedy to a variety of ailments. This all-natural superfood boasts numerous health benefits for the human body – inside and out.
One common question we receive here at Bees & Trees is, “Can Manuka honey’s health and wellness benefits extend to oral care?” This article is written to provide this answer and present an in-depth overview on how to utilize Manuka honey in your oral health care routine, combating common troubles such as bad breath, dental plaque, dental infections and dental diseases.
Properties and Health Benefits of Manuka Honey
As written above, Manuka honey possesses an array of incredible health and wellness properties. These powerful, all-natural health benefits directly correlate with Manuka honey’s Methylglyoxal concentration. Methylglyoxal (MG or MGO) is a naturally occurring organic compound found in Manuka honey. Higher MG concentrations in Manuka honey provide more efficacy or potency in regards to the overall health and wellness properties of the honey. The amazing properties of Manuka honey include: antibacterial, antiviral, anti-inflammatory, antioxidant, antimicrobial and antiparasitic qualities.
Can Manuka Honey Eliminate Bad Breath?
Bad breath, also known as halitosis, is a common oral health concern where the main symptom is bad smelling breath and it can be caused by a variety of reasons such as types of foods, tobacco products, poor oral hygiene, dry mouth, medications, oral infections and nose or throat infections. Manuka honey’s strong antibacterial properties work to eradicate bad bacteria and may be a promising all-natural method in eliminating and preventing bad breath.
One study conducted by Tsurumi University’s Department of Oral Bacteriology, School of Dental Medicine, featured ten healthy subjects. Each subject’s halitosis was measured before and after the intake of Manuka honey or acacia honey. This study found that bad bacteria, causing bad breath, “decreased after intake of both honeys, but the decreasing effect of Manuka honey was markedly stronger than that of acacia honey.”  In addition, “the results indicated that the decreasing effect of halitosis by Manuka honey would originate from the strong antibacterial activity of MGO.”  The research above further reinforces the idea that Manuka honey and it’s potent antibacterial properties may be a great eliminator of bad breath and bad bacteria alike.
What Is Manuka Honey’s Effect on Oral Plaque?
Oral plaque is the sticky, colorless or pale yellow film that is constantly forming on your teeth. When saliva, food and fluids combine, oral plaque forms between your teeth and along the gum line. Oral plaque is composed of bacteria and begins forming on teeth 4-12 hours after brushing in the form of soft bacterial plaque. If soft bacterial plaque is not removed, it begins to harden, making it harder to remove and can potentially lead to an early stage of gum disease called gingivitis. If you are looking for a preventive and/or combatant to oral plaque, Manuka honey and its superior antibacterial properties may serve as both
One study, conducted by the Department of Periodontics, Modern Dental College & Research Centre, researched on Manuka honey’s effect on oral plaque. The study consisted of 6 male students, that were dentally cleaned to be 100% free of oral plaque or calculus (hardened oral plaque), and split into 3 control groups: the Manuka honey rinse group, the chlorhexidine gluconate mouthwash group and the xylitol chewing gum group. The study found that, “[Manuka] honey not only stops the growth of dental plaque bacteria but also reduces the amount of acid produced, which stops the bacteria from producing dextran.  Dextran is an organic compound, from sucrose (sugar), that enables bacteria to form plaque. Similarly, one pilot study found that Manuka honey, “could be used to reduce dental plaque. When using honey, consideration needs to be given to its quality and antibacterial activity.”  The results of the two studies examined above uphold that Manuka honey may have the ability to not only effectively remove oral plaque but prevent the building up of oral plaque due to its antibacterial qualities.
Can Manuka Honey Combat Oral Infections?
It is important to preface this question with a distinction between oral infections in contrast to oral diseases. Oral infections originate at the tooth or its supporting structures and can spread to the surrounding tissue. Oral diseases originate when the cells in your gums or oral tissue become damaged as a result of an oral infection. The most important distinction between both is that oral infections are reversible whereas oral diseases are typically irreversible, but treatable. Oral infections are classified in 3 types: Gingival (infection in the gums), Periapical (infection in the roots of a tooth), and Periodontal (infection in the bone and tissue that support a tooth). Poor oral hygiene, food that includes sugar or starch and untreated tooth cracks or cavities all can cause bad bacteria to multiply and infect a tooth and/or surrounding tissue – all leading to an oral infection.
Manuka honey’s antimicrobial properties work against a broad spectrum of microbes (bacteria, fungi and viruses) to sterilize and cleanse tissue from dangerous germs and may also help reduce inflammation and prevent bacterial infection with continual usage. Research indicates that honey may significantly reduce the severity of oral infections such as oral mucositis. Oral mucositis can occur when cancer radiotherapy treatments break down the rapidly dividing epithelial cells lining the gastro-intestinal tract (which begins from the mouth), leaving the mucosal tissue open to ulceration and infection.
One study, conducted by the Department of Oral Biology, de’ Montmorency College of Dentistry, tested subjects going through radiotherapy and half of the participants orally took 20 mL of honey daily, while the others took a saline solution. The results found that, “In the honey-treated group, the proportion of mucositis was lower and statistically significant as compared to the control group at the end of 6 weeks of radiation.”  The study concluded that, “oral intake of honey during radiotherapy is valuable in the reduction of severity of oral mucositis.”  The previous findings show evidence that the antimicrobial capabilities in honey like Manuka honey target infectious bacteria, decreasing the chances of infection spreading and could prove to be an all-natural alternative to infection prevention.
How Does Manuka Honey Inhibit Oral Diseases?
As stated in the above section, Can Manuka Honey Combat Oral Infections, oral diseases originate when the cells in your gums or oral tissue become damaged as a result of an oral infection. There are several types of oral diseases, this section will focus primarily on common oral diseases such as gingivitis and periodontal disease, which develop from untreated oral infections in the gums.
Gingivitis is a form of gum disease where the gums separate from the teeth, causing inflamed, swollen, puffy, receding or tender gums. Untreated gingivitis can lead to tooth loss and periodontal disease. Periodontal disease is a serious gum disease that occurs when gingivitis is left untreated. This disease damages gums, can destroy the jawbone and is usually caused by poor oral hygiene. Symptoms include swollen, red, and tender gums.
Manuka honey’s powerful antibacterial properties have been researched in search of a holistic inhibitor against oral diseases. One pilot study, conducted by the School of Dentistry, University of Otago, researched whether Manuka honey with high antibacterial activity could reduce dental plaque and clinical levels of gingivitis. The study featured 30 participants that chewed or sucked on Manuka honey chewable “honey leather” gum or sugarless chewing gum, 3 times a day for 10 minutes. “Analysis of the results indicated that there were statistically highly significant reductions in the mean plaque scores, and the percentage of bleeding sites, in the manuka honey group, with no significant changes in the control group.”  The study concluded that the, “results suggest that there may be a potential therapeutic role for manuka honey confectionery in the treatment of gingivitis and periodontal disease.”
