Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Polyphenols, a diverse group of naturally occurring compounds found in plants (such as flavonoids, phenolic acids, and tannins), have been studied for their potential role in supporting gum (periodontal) health. Scientific research suggests that polyphenols possess anti-inflammatory, antioxidant, and antimicrobial properties, which can be beneficial in the context of oral health and specifically for the gums. For example, green tea catechins (a type of polyphenol) have been shown to inhibit the growth of periodontal pathogens and reduce inflammation in gingival tissues. Several in vitro and clinical studies have demonstrated that polyphenol-rich extracts from sources like green tea, cranberries, and grapes can reduce the formation of dental plaque, inhibit bacterial adhesion, and modulate the host inflammatory response.

While there is promising evidence, most studies have been small, of short duration, or have used specific extracts rather than generalized "mixed polyphenols." Furthermore, polyphenols are often used as adjuncts to standard oral hygiene practices rather than stand-alone therapies. Systematic reviews and meta-analyses suggest a moderate benefit for gum health, especially in reducing gingival inflammation and bleeding. However, more large-scale, long-term clinical trials are needed to establish optimal dosing, efficacy, and safety for generalized use of mixed polyphenols in supporting gum health.
