Our toothpaste for stain removal contains sodium lauryl sulfate and hydroxypropyl methyl cellulose. It helps protect dental health, deep cleaning and removal of small and deep stains. The way to use it is simple: squeeze a small amount of toothpaste on the toothbrush and brush for more than 2 minutes. Then gargle with water and brush once every morning and night to make the brightening effect better. After use, it gently cleans the teeth and has a fresh mint scent to keep the mouth odor clean and remove bad breath.
