Either smoking or chewing tobacco can make the enamel of the teeth more likely to stain and also cause dental problem as well as medical problems. Prolonged smoking darkens the teeth and leaves tough stains. These stains with time get absorbed deep into the enamel and if ignored, may cause major oral problems.

• Practice good oral hygiene: the most common way to get rid of stains is to brush and floss your teeth daily. Rinse your mouth will help to removing bacteria that causes stain.
• Hydrogen peroxide: rinsing your mouth with hydrogen peroxide mouthwash reduce the staining.
