Teeth whitening is a popular cosmetic dental treatment to enhance the appearance of teeth by lightening their color. Over time, teeth can become discolored or stained due to factors such as aging, consumption of certain foods and beverages, smoking, and poor oral hygiene. Teeth whitening treatments can be effective in removing stains and discoloration, resulting in a brighter and more youthful smile. However, it is important to note that the results may vary depending on the individual’s starting tooth color and the degree of staining. Additionally, teeth whitening is not suitable for everyone, such as pregnant or nursing women, children, and individuals with certain dental conditions.
