Teeth whitening is the process of lightening the color of your teeth to remove stains and discoloration. It is a popular cosmetic dental procedure that can be done professionally or at home. The desire for whiter teeth has significantly increased over the years, leading to the development of various whitening products and techniques.

Over time, the enamel can become stained or discolored due to various factors such as aging, consumption of certain foods and drinks, smoking, poor dental hygiene, and certain medications.
