Catechins are a type of flavonoid commonly found in green tea, cocoa, and certain fruits. There is a growing body of scientific evidence suggesting that catechins, particularly epigallocatechin gallate (EGCG), can support oral health, including the health of the gums. Several in vitro and clinical studies have demonstrated the antibacterial and anti-inflammatory properties of catechins, which are relevant for gum health. For example, catechins can inhibit the growth of Porphyromonas gingivalis and Streptococcus mutans, bacteria implicated in periodontal disease and dental caries. Clinical trials have shown that green tea catechin-containing mouthwashes or gels can reduce gingival bleeding, plaque formation, and markers of inflammation in individuals with gingivitis or mild periodontitis. The mechanisms appear to involve both direct antimicrobial action and modulation of host inflammatory responses. However, most studies use green tea extracts standardized for catechin content, and results can vary depending on the specific formulation and dosage. While more large-scale and long-term studies are needed to confirm the magnitude of benefit, current evidence supports the adjunctive use of catechins for maintaining healthy gums.
