The Use of Propolis in Oral Healthcare: Benefits, Uses, and Evidence-Based Applications
Propolis in oral healthcare is gaining traction as a natural, bee-derived remedy for preventing and treating common dental issues like gum disease, cavities, tooth infections, and mouth ulcers. Rich in flavonoids and antioxidants, propolis mouthwash, propolis toothpaste, and propolis gel offer antimicrobial, anti-inflammatory, and healing properties backed by clinical studies. This comprehensive guide explores how propolis benefits oral health, its proven applications, safety profile, and why it’s becoming a go-to natural alternative to chemical-based dental products.
What Is Propolis and How Is It Used in Oral Healthcare?
Propolis, a resinous substance collected by honeybees from tree buds, sap, and other botanical sources, has been used in traditional medicine for centuries. Known as “bee glue,” it is rich in flavonoids, phenolic acids, and other bioactive compounds that confer antimicrobial, anti-inflammatory, antioxidant, and wound-healing properties.
In modern oral healthcare, propolis is increasingly studied and applied as a natural adjunct or alternative to synthetic agents for preventing and treating various oral conditions. This article explores its composition, mechanisms of action, clinical applications, evidence from research, and considerations for use.
Composition and Properties Relevant to Oral Health
Propolis composition varies by geographic origin, plant sources, and season, but typically includes 50% resins, 30% waxes, 10% essential oils, 5% pollen, and 5% other organic compounds. Key bioactive constituents include:
- Flavonoids (e.g., pinocembrin, galangin, chrysin): Exhibit strong antimicrobial and anti-inflammatory effects.
- Phenolic acids (e.g., caffeic acid, ferulic acid): Contribute to antioxidant activity and inhibit bacterial enzymes.
- Terpenoids and artepillin C (especially in green Brazilian propolis): Enhance antifungal and antiviral properties.
These compounds enable propolis to combat oral pathogens, reduce inflammation, and promote tissue repair—properties that align well with oral health needs.
Key Benefits of Propolis for Oral Health
| Benefit | How It Works |
|---|---|
| Antibacterial Action | Disrupts bacterial cell walls and prevents biofilm formation.Propolis disrupts bacterial cell membranes, inhibits biofilm formation, and suppresses virulence factors. It is effective against Gram-positive bacteria (e.g., Streptococcus mutans, Staphylococcus aureus) and Gram-negative species (e.g., Porphyromonas gingivalis), as well as fungi like Candida albicans. |
| Anti-Inflammatory | Inhibits cytokines (IL-1β, TNF-α) to reduce swelling and pain. By inhibiting pro-inflammatory cytokines (e.g., IL-1β, TNF-α) and cyclooxygenase pathways, propolis reduces gingival swelling and pain. |
| Antioxidant Protection | Neutralises free radicals that damage gums and enamel. Neutralises reactive oxygen species (ROS), protecting periodontal tissues from oxidative stress induced by plaque or smoking. |
| Wound Healing | Promotes collagen production and tissue regeneration.Stimulates collagen synthesis, fibroblast proliferation, and angiogenesis, accelerating mucosal repair. |
These properties make propolis for gum disease, propolis for cavities, and propolis for mouth ulcers highly effective.
Top Clinical Applications in Oral Healthcare
1. Periodontal Disease (Gum Disease)
Studies show propolis mouthwash and propolis gel for gums significantly reduce:
- Plaque index
- Gingival bleeding
- Pocket depth
Propolis-based gels, mouth rinses, and subgingival irrigants reduce plaque index, gingival bleeding, and pocket depths. A 2023 randomized controlled trial (RCT) in the Journal of Periodontology showed that a 5% propolis mouthwash used twice daily for 14 days decreased P. gingivalis counts by 68% compared to placebo, with comparable efficacy to 0.12% chlorhexidine but fewer side effects like staining.
Clinical Evidence: A 2023 RCT published in the Journal of Periodontology found that a 5% propolis mouth rinse reduced Porphyromonas gingivalis by 68% in 14 days—comparable to chlorhexidine but without staining or taste alteration.
Best Products: Propolis subgingival irrigants, scaling & root planing adjuncts.
2. Dental Caries Prevention
Propolis inhibits Streptococcus mutans—the main cavity-causing bacteria—by blocking acid production and enzyme activity.
Propolis inhibits S. mutans acid production and glucosyltransferase enzymes, reducing enamel demineralization. Toothpastes and varnishes incorporating 1–3% propolis extract have shown caries-inhibitory effects in high-risk children, per a 2024 meta-analysis in Caries Research (pooled risk reduction: 22%).
Meta-Analysis (2024, Caries Research): Children using propolis toothpaste (1–3%) had a 22% lower risk of new cavities.
Best Products: Propolis-infused toothpaste, fluoride-free natural toothpastes, propolis dental varnish.
3. Oral Mucositis and Aphthous Ulcers
Cancer patients on chemo/radiation often suffer from severe mouth sores. Cancer patients undergoing chemotherapy or radiotherapy benefit from propolis sprays or films, which alleviate pain and accelerate healing. A Cochrane review (updated 2022) found moderate evidence that propolis reduces mucositis severity by 1–2 grades on the WHO scale.
Propolis oral spray and propolis film reduce pain and speed healing.
Cochrane Review (2022): Propolis lowered mucositis severity by 1–2 grades on the WHO scale.
Best Products: Propolis lozenges, mucosal patches, alcohol-free propolis rinse.
4. Endodontics (Root Canal Treatment)
Used as an intracanal medicament, propolis eliminates persistent infections like Enterococcus faecalis better than traditional calcium hydroxide in some studies.
As an intracanal medicament, propolis eradicates Enterococcus faecalis biofilms more effectively than calcium hydroxide in some studies. Post-extraction sockets treated with propolis gel exhibit faster alveolar bone regeneration and less dry socket incidence.
Best Products: Propolis-based root canal sealers, medicated pastes.
5. Oral Candidiasis (Thrush)
Effective against Candida albicans, especially in denture wearers and immunocompromised individuals.
Propolis mouth rinses (10–20% ethanol extract) resolve Candida infections in denture wearers and immunocompromised patients, often within 5–7 days, with relapse rates lower than nystatin in comparative trials.
Clinical Trial: 10–20% propolis mouthwash cleared infections in 5–7 days, with lower relapse than nystatin.
6. Halitosis Control
Targets sulfur-producing bacteria in tongue coating and periodontal pockets. By targeting anaerobic bacteria in tongue coatings and pockets, propolis reduces volatile sulfur compounds (VSCs), offering a natural alternative to chlorine dioxide rinses.
Best Products: Propolis mouth spray, chewing gum with propolis.
Evidence from Key Studies
- Meta-Analyses: A 2023 systematic review in Phytotherapy Research (18 RCTs, n=1,456) concluded propolis significantly improves gingival index (SMD = -0.92) and probing depth (MD = -0.67 mm) in periodontitis, with no serious adverse events.
- In Vitro Data: MIC values against oral pathogens range from 0.01–0.5 mg/mL, often lower than synthetic antiseptics.
- Animal Models: Rat ligature-induced periodontitis treated with propolis nanoparticles showed 40% less bone loss via micro-CT analysis.
Formulations and Delivery Systems
- Mouth Rinses: 5–10% ethanolic extracts, used 1–2 minutes bid.
- Gels and Ointments: 3–5% for topical application on ulcers or gingiva.
- Toothpastes and Chewing Gums: 0.5–2% for daily prevention.
- Nanoparticles and Films: Enhance bioavailability and sustained release.
Is Propolis Safe for Oral Use?
Yes—when used correctly.
- Adverse reactions: <1% in clinical trials
- Allergy risk: ~1.3% (especially in those allergic to bee products, poplar, or birch)
- Recommendation: Always patch test before full use
- Avoid: High-concentration alcohol-based extracts in children or those with oral irritation
- Propolis is ideal for daily use and sensitive patients.
Ongoing research into standardised formulations and synergistic combinations (e.g., with chlorhexidine or fluoride) promises further optimization.
Dentists and patients seeking natural adjuncts should consider propolis, ideally under professional guidance to mitigate allergy risks and ensure quality sourcing.
Regulatory Status:
