Natural teeth should always have a slight yellow tint. That's due to the color of dentin, the center of your tooth. Enamel is slightly translucent, allowing the yellowish dentin shows through. Over time, stains from food, drinks, and daily wear can make teeth appear even more yellow, especially as enamel develops more micro-cracks that allow the dentin to become more visible through the pores.

Hydroxyapatite, the key ingredient in ENML toothpaste tablets, addresses this by filling in those pores and irregularities in the enamel surface. This remineralization process smooths the enamel, reducing the enamel translucency, while restoring the teeth's natural white appearance without harsh chemicals or bleaches.

If you brush with ENML every day, twice a day, you'll notice a visible difference in just 30 days, a whiter, healthier smile that feels as good as it looks.

Traditional whitening methods, like peroxide-based bleaches (hydrogen or carbamide peroxide), work by oxidizing organic stains to break them into smaller pieces, lightening the tooth color. These include in-office treatments with high concentrations (15-43% peroxide) or at-home options like strips and gels (3-20% peroxide). However, they can be harmful: overuse leads to tooth sensitivity, gingival irritation, enamel demineralization, and dehydration, potentially thinning the enamel and increasing vulnerability to damage. Abrasive toothpastes add to this by wearing down the surface.

These methods can also create an unnatural white appearance by over-bleaching beyond the natural shade, resulting in opaque, chalky, or bluish teeth that look artificial—often because thinned enamel exposes more dentin or scatters light unevenly. In contrast, naturally white teeth—with their subtle off-white or light yellow hue from healthy dentin and intact enamel—always look the healthiest, as they indicate strong structure without damage from aggressive treatments.
