Whitening toothpaste is a type of dental product designed to help remove stains and lighten the color of teeth. It typically contains mild abrasives and special chemical agents that work to break down surface stains caused by food, drinks, and smoking. Regular use can lead to a brighter smile, although results may vary depending on the individual and the specific product. Most whitening toothpastes are safe for daily use and can be found in many brands at grocery stores and pharmacies. However, they are not a substitute for professional dental treatments, such as teeth whitening procedures performed by a dentist.
