Xylitol (birch sugar) is a natural sugar alcohol found in birch bark and many fruits – and has been extensively researched in dental care since the 1970s. Unlike sugar, it doesn't serve as an energy source for cavity-causing bacteria – they can't metabolize it, and therefore can't produce acid. This way, xylitol supports a healthy oral flora and contributes to a balanced pH environment in the mouth. Decades of clinical studies demonstrate a significant effect on dental health in both children and adults.

Rügen healing chalk (calcium carbonate) is a natural, mineral-rich active ingredient from a German, environmentally friendly source – composed of approximately 98% natural calcium carbonate. Thanks to its especially fine structure, it gently removes plaque, discoloration, and buildup without stressing the enamel. At the same time, it has a pH-balancing effect in the mouth and releases calcium directly to the enamel – acting as a natural mineral reservoir for healthy, resilient teeth.

Hydroxyapatite (HAP) is the mineral that makes up about 97% of human tooth enamel – an endogenous, purely mineral active ingredient. In biomimetic form, it integrates directly into the tooth surface, filling microscopic enamel defects and supporting natural remineralization. It contributes to smooth tooth enamel, reduces the sensation of tooth sensitivity and makes teeth appear naturally brighter.

Sodium bicarbonate (baking soda) has an RDA abrasivity value of just 7, making it one of the gentlest cleaning agents in dental care – more than ten times gentler than many conventional toothpaste abrasives. Rather than removing plaque through abrasion, it works through physical disruption of the biofilm matrix – a unique mechanism that breaks down plaque without stressing the enamel. At the same time, baking soda has a pH-balancing effect in the mouth, creating an environment where teeth and gums can thrive. Clinical studies show a positive effect on gum appearance with regular use.

Zinc citrate is a well-tolerated, pH-neutral form of the essential trace mineral zinc, making it particularly suitable for oral care. It helps support a healthy oral microbiome, contributes to healthy teeth and gums, and promotes long-lasting freshness. In a clinical study (Scientific Reports, 2025), zinc citrate showed a positive effect on the composition of the oral microbiome. It also helps maintain clean-looking teeth and supports a long-lasting fresh feeling.

Coconut oil (Cocos nucifera) contains around 50% lauric acid, a medium-chain fatty acid that also occurs naturally in the pellicle – the protective protein layer that reforms on the tooth enamel after brushing. It helps support a healthy oral microbiome and contributes to healthy, resilient gums. Coconut oil also leaves your mouth feeling pleasantly smooth while complementing the cleansing power of the Toothpowder with its natural caring properties.

Organic peppermint essential oil contains approximately 40–55% menthol and 20–30% menthone—two of the most extensively researched compounds in natural oral care and key ingredients in many established oral care products worldwide. It helps support a healthy oral microbiome, contributes to a clean, fresh mouthfeel, and activates cold-sensitive receptors in the oral mucosa through menthol, providing a long-lasting sensation of freshness. It also stimulates saliva production, which plays an important role in maintaining a healthy oral environment.

It helps support a healthy oral microbiome, promotes a clean, fresh feeling in the mouth, and activates cold-sensitive receptors in the oral mucosa through its naturally occurring menthol, providing a long-lasting sensation of freshness. It also stimulates saliva production, which plays an important role in maintaining a healthy oral environment.

Organic ginger extract (Zingiber officinale) contains gingerols and shogaols—bioactive compounds with a long history of use in natural oral care and increasingly well-documented benefits for gum tissue. In cell studies using primary human gingival cells, ginger extract showed positive effects on the gingival tissue environment. It helps support healthy gums and contributes to a balanced oral microbiome through its naturally broad spectrum of beneficial properties.

Organic Java turmeric extract (Curcuma xanthorrhiza) with xanthorrhizol is obtained through a gentle CO₂ extraction process. Unlike common turmeric (Curcuma longa), Java turmeric is naturally rich in xanthorrhizol—a sesquiterpene with an exceptionally well-documented profile in oral care research. It helps support a healthy oral microbiome and contributes to clean, healthy-looking teeth. The CO₂ extraction process minimizes the yellow-colored curcuminoids, delivering the benefits of the extract without staining your teeth.

Organic lemongrass essential oil (Cymbopogon citratus) contains approximately 70–80% citral—a naturally occurring compound with a broad range of benefits for oral care. It helps support a healthy oral microbiome, contributes to healthy gums and clean teeth, and supports oral health across a wide range of common oral microorganisms. Laboratory studies have shown that it helps inhibit biofilm adhesion on tooth enamel while remaining well tolerated by oral mucosal cells. Its fresh, citrusy aroma also makes brushing a more enjoyable experience.

Organic rosemary essential oil contains carnosic acid, carnosol, and 1,8-cineole—bioactive compounds with a broad range of benefits for oral care. A 2022 study conducted by Freiburg University Medical Center demonstrated that rosemary extract helps inhibit the initial adhesion of bacteria to oral mucosal surfaces, preventing the first step in plaque formation. It helps support a healthy oral microbiome, contributes to healthy gums, and helps protect gum tissue through its natural antioxidant properties.

Organic thyme essential oil contains thymol—a bioactive compound recognized by the American Dental Association (ADA) as an effective ingredient in oral care and used in clinically established oral care products. It helps support a healthy oral microbiome through its broad spectrum of naturally beneficial properties and contributes to healthy teeth and gums. Molecular studies have demonstrated that thymol binds directly to structural proteins of oral bacteria, providing insight into its mechanism of action at the molecular level.

Organic mandarin essential oil (Citrus reticulata) contains not only the well-researched compound d-limonene, but also particularly high levels of γ-terpinene and linalool—a combination that gives mandarin oil one of the highest antioxidant capacities among citrus essential oils. It helps support a healthy oral microbiome, contributes to healthy gums, and leaves your mouth feeling pleasantly soothed thanks to its naturally occurring linalool. Its soft, sweet citrus aroma makes your daily oral care routine a truly enjoyable sensory experience.

Organic vanilla (Vanilla planifolia, ground) contains vanillin—a phenolic aldehyde classified by the U.S. Food and Drug Administration (FDA) as GRAS (Generally Recognized As Safe), the highest safety designation for ingredients intended for oral use. In cell studies using primary human gingival fibroblasts, vanillin showed positive effects on the gingival tissue environment and collagen synthesis. It helps support healthy gums and contributes to a healthy oral environment. Its warm, distinctive aroma turns your daily oral care routine into an enjoyable experience, encouraging the consistency that is key to good oral hygiene.

Organic chamomile essential oil (German chamomile, Matricaria chamomilla) is rich in α-bisabolol and chamazulene—two bioactive compounds that have been valued for centuries for their soothing and caring properties on skin and mucosal tissue. It helps support healthy, resilient gums and contributes to the well-being of the oral mucosa. Chamomile is officially recognized by the European Union as a Traditional Herbal Medicinal Product (THMP) for the care of the oral mucosa.

Organic orange essential oil (Citrus sinensis) contains approximately 90–95% d-limonene—the highest naturally occurring limonene content of any citrus essential oil. It helps support a healthy oral microbiome, contributes to clean, healthy-looking teeth, and helps reduce plaque buildup. In compatibility studies, orange essential oil demonstrated good tolerability for human oral mucosal cells. Its bright, fresh citrus aroma perfectly complements the flavor of the Toothpowder.
