Liquid Biome+ Oral Rinse is a doctor-formulated oral care innovation powered by TrueBiotic® technology and biomimetic hydroxyapatite. Designed as a daily ritual, it complements brushing by supporting microbial balance, protecting enamel, and maintaining freshness without harsh chemicals.

It contains TrueBiotic®, a unique postbiotic blend developed to nurture a balanced oral microbiome—the foundation of lasting oral and overall health. With added hydroxyapatite, the same mineral that makes up 97% of natural enamel, the formula reinforces tooth surfaces and helps maintain mineral balance in a fluoride-free format. Unlike conventional rinses that rely on alcohol or detergents, Liquid Biome+ works gently with the body’s natural defences, avoiding disruption to the oral ecosystem.

By addressing causes of bad breath rather than masking them, this rinse promotes clean breath, supports daily enamel care, and contributes to the health of both mouth and gut. Made with gentle, alcohol-free ingredients and free from harsh foaming agents, Liquid Biome+ is suitable for everyday use—even for sensitive mouths that need a softer approach.

Most high street mouthwashes use alcohol, chlorhexidine, or triclosan to kill bacteria, but this approach disrupts the balance of the oral microbiome. While these ingredients may offer temporary freshness, they also eliminate beneficial microbes that support long-term oral harmony. Liquid Biome+ takes a different path with hydroxyapatite and TrueBiotic® postbiotics that work in partnership with the body. Postbiotics deliver the functional benefits of probiotic science without the instability of live bacteria, creating an environment that allows beneficial species to thrive. This gentle, microbiome-aware approach helps you maintain enamel strength, balanced oral health, and lasting freshness every day.
