Teeth whitening, also known as tooth bleaching, is a cosmetic dental procedure that lightens the color of teeth. It can be done in the dentist's office or at home using over-the-counter products.
There are many reasons why people may want to whiten their teeth. Some people have naturally yellow or discolored teeth, while others may have teeth that have become stained over time from drinking coffee, tea, or red wine. Teeth can also become discolored from smoking or from taking certain medications.
