Tannins are a phytonutrient in tea that can cause discoloration of your teeth by binding to the enamel of your teeth and increasing the discoloration of various food items you consume. Tea Burn has specific ingredients to bind the tannins in the tea and reduce this discoloring effect.
Sodium bicarbonate is also added to bind the tannins in the tea to both prevent it from staining your teeth and help reduce any potential gastrointestinal distress tea may cause.
