Our Tooth whitening toothpaste contains xylitol, sorbitol, and reduces yellow discoloration or stains by counteracting color degradation and restoring a brighter smile to your teeth. It is also gentle on sensitive teeth and gums and does not strip enamel or irritate gums. Its use method is very simple: first, after brushing your teeth normally, take an appropriate amount of this product on the toothbrush, and then gently brush your teeth in a circular motion from inside to outside for 1-2 minutes, and finally rinse with water. Neutralize the yellow in your teeth more naturally, thus hiding stains, increasing brightness, and refreshing your breath.
