Our oral care toothpaste contains hyaluronic acid, sodium bicarbonate (baking soda). It protects tooth enamel from acid attack and enhances tooth protection. Its use is very simple: take an appropriate amount of this product on the toothbrush, brush gently for 3 minutes with the correct brushing method, and rinse your mouth thoroughly with water. And it can remove stains on the surface of the teeth, making the teeth whiter and brighter.
