Xylitol is a well-researched sugar alcohol with a specific and documented mechanism against tooth decay. Streptococcus mutans, the primary bacteria responsible for cavities, absorbs xylitol thinking it is sugar, but cannot metabolize it. The result is a disruption of the bacterium's energy pathway, reduced ability to adhere to tooth surfaces, and a less acidic oral environment. Xylitol is one of the most evidence-backed ingredients in oral health supplementation.*

Guava leaf (Psidium guajava) provides antimicrobial and anti-inflammatory compounds that have been studied specifically for oral health applications. Research has examined its ability to support healthy gum tissue, reduce harmful oral bacteria counts, and contribute to a balanced oral microenvironment. It complements xylitol's antibacterial action with a botanical anti-inflammatory dimension.*

The oral microbiome contains hundreds of bacterial species, and imbalance, driven by diet, antibiotics, or inadequate oral care, is associated with plaque buildup, gum issues, and bad breath. Oral-specific probiotic strains help repopulate the mouth with beneficial bacteria that crowd out harmful species, supporting a balanced environment linked to fresher breath and healthier gums.*

MCHA is a bioavailable form of calcium phosphate, the exact mineral that makes up tooth enamel. Rather than forming a foreign mineral layer on the tooth surface, MCHA provides the actual building blocks the body uses to maintain and remineralize enamel through its natural mineral deposition process. It is particularly relevant for people with sensitive teeth or those concerned about enamel thinning with age.*
