Low abrasivity


Over the years, people have mistakenly concluded that baking soda is highly abrasive. It’s true that some may perceive a slightly gritty texture in toothpastes with baking soda, but the fact is that baking soda crystals are soft and won’t scratch tooth enamel.

Baking soda is a mild polishing agent which removes superficial stains. When mixed with water, much of baking soda breaks down into microscopic particles that get into areas of tooth enamel other toothpastes can’t reach. These baking soda particles then dissolve deeper stains.

Bottom line: Studies prove baking soda is actually the least abrasive polishing agent1 as well as highly soluble in water, making it gentle on enamel, dentin and soft tissue.2,3,4
