How does it happen?

Not just green tea, the same can be said for herbal teas as well, though their staining properties is lesser than that of black tea. Green tea contains plant compounds known as tannins which increase the staining potential of teeth although to a lesser degree than black tea.” But how and why do teas in general stain the teeth? “Such drinks are acidic in nature and increase the porosity of the enamel (outer layer) of teeth. This makes it easier for the pigmented molecules found in teas to adhere to the enamel and therefore cause staining,” she explains.

You need to be careful with these three things in your foods :

  • Chromogens — compounds with strong pigments that cling to enamel
  • Tannins — plant-based compounds that make it easier for stains to stick to teeth
  • Acids — these make tooth enamel softer and rougher, so it’s easier for stains to set in

Like tannins in tea , Caffeine in coffee has a corrosive effect on the tooth enamel. In addition, the acid in coffee can contribute to the wearing away of enamel, which exposes the yellower layer beneath it called dentin. Some other drinks which are high acidic in nature are orange juice, tea, tomatoes and other citrus juices. Cola, wine, sauces like soy, tomato and curry sauce also tend to stain teeth. Smoking also causes staining and discolouration of the teeth due to the nicotine present in it. Both red as well as white wine too can stain the teeth.
