When shopping for natural toothpaste, most people focus on avoiding fluoride, SLS, or artificial sweeteners. But there's another ingredient worth examining: glycerin. While it's found in nearly all commercial toothpastes—including many labeled "natural"—emerging research suggests it may interfere with the body’s natural ability to remineralize enamel. In this post, we explore what glycerin is, why it’s used, and why switching to a glycerin-free toothpaste like Real Skin Care’s coconut oil formula may be a better choice for your oral health.
What Is Glycerin and Why Is It Used in Toothpaste?
Glycerin is a colorless, odorless, and sweet-tasting liquid derived from plant or animal fats. In toothpaste, it's used to:
- Prevent Drying: Keeps the paste smooth and moist in the tube
- Enhance Texture: Gives toothpaste its creamy consistency
- Improve Taste: Adds mild sweetness without sugar
Glycerin is considered non-toxic and safe for consumption. However, its role in oral health is more complicated than it first appears.
Why Avoid Glycerin in Toothpaste?
Many holistic dentists and functional oral care practitioners advise against glycerin in toothpaste. The concern is that glycerin may leave a thin coating on your teeth—one that doesn’t rinse away easily. This layer could block saliva from naturally remineralizing tooth enamel, a process essential for cavity prevention and enamel repair.
While the science is still emerging, studies and dental professionals increasingly support a glycerin-free approach, especially for people with:
- Enamel erosion
- Sensitivity or frequent cavities
- Dry mouth or oral pH imbalance
- Post-whitening sensitivity
Benefits of Glycerin-Free Toothpaste
- Supports Natural Remineralization: Allows saliva to nourish and repair enamel without interference
- Cleaner Mouthfeel: No residue left behind after brushing
- Better for Sensitive Mouths: No chemical coating or film
- Truly Natural: A sign of minimal, intentional formulation
