Fennel for Dental And Oral Health

Research suggests that fennel demonstrates several properties relevant to dental and oral health, with studies indicating antimicrobial activity against cariogenic bacteria, antifungal effects against oral Candida species, and the ability to raise both salivary and plaque pH levels. Clinical studies have also found that chewing fennel seeds increases plaque calcium concentration, which researchers have associated with a potentially protective effect on tooth enamel. The available evidence comes primarily from in vitro laboratory studies and small clinical investigations rather than large randomized controlled trials, which limits the strength of conclusions that can be drawn about real-world efficacy. Studies indicate a consistently supportive directional trend across these findings, though the body of research remains relatively small and further well-controlled human trials would be needed to more firmly establish fennel's role in oral health applications.
