Whitening toothpaste is a type of toothpaste designed to remove stains and discoloration from teeth, helping to enhance their brightness. It typically contains mild abrasives and chemical agents that work to polish the teeth and break down surface stains caused by food, drinks, and smoking. Many whitening toothpastes also include ingredients like hydrogen peroxide or baking soda, which can help to lighten the color of teeth over time. While they can improve the appearance of teeth, results may vary, and they are generally less effective than professional whitening treatments offered by dentists.
