Teeth whitening is a cosmetic dental procedure that aims to lighten the color of the teeth and remove stains or discoloration. It is a popular and non-invasive treatment that can improve the appearance of the teeth and enhance the overall smile.

Teeth whitening can be effective for removing stains caused by factors such as aging, smoking, or consuming certain foods or beverages. However, it may not be effective for all types of discoloration, such as discoloration caused by certain medications or dental procedures.
