Eugenol, a compound primarily found in clove oil, has been used for centuries in dental care and oral health, particularly for its analgesic and antiseptic properties. Scientific studies support its efficacy in oral and gum health. Eugenol exhibits significant anti-inflammatory, analgesic, and antimicrobial effects, which are particularly beneficial for gum tissues. It is commonly used in dentistry as a component of temporary dental fillings and as a topical analgesic for toothaches and inflamed gums. Numerous in vitro and in vivo studies have demonstrated that eugenol can inhibit the growth of oral pathogens such as Streptococcus mutans and Porphyromonas gingivalis, both of which are associated with gum disease.

Additionally, clinical studies have shown that products containing eugenol can reduce symptoms of gingivitis and other minor gum irritations, likely due to its anti-inflammatory action. However, while the evidence supports its effectiveness for symptomatic relief and as an adjunct in maintaining gum health, eugenol should not be seen as a substitute for standard dental care or more established treatments for periodontal disease. In rare cases, eugenol can cause allergic reactions or irritation in sensitive individuals. Overall, eugenol's use for supporting gum health is backed by scientific evidence, particularly for temporary pain relief and antimicrobial support, but further research is needed to fully clarify its long-term benefits and safety profile.
