Loved for 3 Years: Easy Rinse, Clean Teeth

We have been using this product for three years now, great product. Rinses easily and leaves your teeth clean!

Understanding the Science Behind This Unique Toothpaste

This powder toothpaste is formulated with a proprietary blend of food-grade diatomaceous earth, non-GMO birch xylitol, organic matcha, organic peppermint, and organic Ceylon cinnamon. Let's break down the key ingredients and how they work together to support oral health.

Diatomaceous Earth (DE) – Gentle Abrasive & Natural Polish

Food-grade diatomaceous earth is a fine powder made from fossilized algae (diatoms). Its microscopic, porous structure provides a gentle abrasive action that helps remove plaque and surface stains without damaging enamel. Unlike harsh abrasives in conventional toothpastes, DE is non-toxic and also helps balance oral pH. Studies suggest it may even help remineralize teeth by delivering silica, which is essential for bone and enamel strength.

Xylitol – Cavity Fighter & Sweetener

Xylitol is a natural sugar alcohol derived from birch trees or corn. It does not feed cavity-causing bacteria and actually inhibits their growth. By disrupting bacterial adhesion, xylitol helps reduce plaque formation and lowers the risk of cavities. It also stimulates saliva flow, which naturally buffers acids and repairs early enamel demineralization. This product uses non-GMO birch xylitol for purity.

Matcha Green Tea – Antioxidant & Gum Protector

Organic matcha is a concentrated form of green tea powder rich in catechins (antioxidants). These compounds fight inflammation, reduce gum swelling, and combat bad breath. Matcha also contains fluoride naturally, contributing to enamel remineralization. Its chlorophyll content gives the toothpaste a pleasant green color and helps neutralize odor-causing compounds.

Peppermint & Cinnamon – Fresh Breath & Antimicrobial

Organic peppermint oil provides a cooling, refreshing sensation and has natural antimicrobial properties that help control bacterial growth. Ceylon cinnamon (true cinnamon) is gentler than cassia cinnamon and offers anti-inflammatory and antibacterial benefits, particularly against Streptococcus mutans, the primary bacteria behind tooth decay. Together, they leave your mouth feeling clean and invigorated.

Remineralization Formula – Works with Yogurt

The brand's unique approach involves mixing the powder with yogurt (dairy or non-dairy) to create a paste. Yogurt is rich in probiotics (live beneficial bacteria), calcium, and phosphorus. When combined with the powder, the mixture creates an optimal pH environment (around 7–8) that promotes remineralization of enamel. The probiotics help balance the oral microbiome by crowding out harmful bacteria. This synergistic effect is believed to strengthen teeth and gums more effectively than using powder alone.

How to Use This Toothpaste

Simply mix one scoop of the powder (included) with a small amount of yogurt to form a paste. Brush thoroughly for two minutes, then allow the mixture to naturally dissipate in your mouth – no rinsing required! The powder should not be swallowed in large amounts, but the small residual left after brushing is safe. Many users report that it leaves their teeth feeling smooth and clean, just as the reviewer noted: “Rinses easily and leaves your teeth clean.”

Why Choose This Over Conventional Toothpaste?

Most commercial toothpastes contain glycerin, triclosan, sodium lauryl sulfate (SLS), artificial sweeteners, and other chemicals. Glycerin can coat teeth and prevent remineralization; SLS may cause mouth irritation; triclosan is linked to hormonal disruption. This powder is free from all such additives. It is also gluten-free, vegan-friendly, and comes in a convenient 4-ounce glass jar with a measuring scoop. The product has been on the market since 2018 and holds a 4.1-star rating from over 2,000 customers, demonstrating its reliability.

Who Should Use It?

Ideal for those seeking a natural, chemical-free oral care alternative, especially individuals with sensitive gums, receding enamel, or a desire to reduce plastic waste (glass jar, no tube). It is also suitable for people looking to support remineralization after whitening treatments or during orthodontic care. However, those with dental restorations (veneers, crowns) should consult their dentist first, as some abrasives may affect bonding materials.

Potential Drawbacks & Tips

Because this product does not contain foaming agents like SLS, it feels different from traditional toothpaste – it may seem less “sudsy.” The taste is mild and earthy due to matcha and cinnamon; some users initially miss the strong minty flavor. To adjust, you can add a drop of your own peppermint oil. The powder can be messy if not handled carefully; use the scoop over a sink. Finally, ensure you mix with high-quality yogurt (preferably plain, unsweetened) to avoid added sugars.

Conclusion

The reviewer's three-year loyalty speaks volumes. With its natural ingredients, remineralization-friendly formula, and easy-rinse texture, this powder toothpaste delivers on its promise of gentle yet effective cleaning. Whether you're a long-time user or trying natural oral care for the first time, this product is a solid choice for healthier teeth and gums.
