Green tea is made from the unfermented leaves of Cameillia Sinensis. Enriched with numerous benefits, it can have negative effects too if taken excessively.

Green tea can have some unwanted effects on your teeth if you consume it excessively.  For instance, if you consume green tea with no sugar or very less amount of sugar, it can be beneficial for your teeth. But, if you take it in a large quantity with much sugar added, it is no less than candies or ice-creams and can harm your teeth.

Green tea may stain your teeth

There are two ways how your teeth get stained. The first one is the intrinsic stain, which occur by things such as nutritive absences, trauma, cavities, etc. The second one is extrinsic stain, which occur by exterior issues such as drinks and foods.


How does green tea stain your teeth?

Not many people are aware of the fact that drinking green tea excessively can stain your pearly white teeth. It is because green tea (and all other herbal drinks) contains tannins, an element majorly responsible for teeth staining.

High intake of green tea does not actually damage your teeth but only stains them. However, adding too much sweetness in your green tea will damage your teeth.

Green tea is acidic in nature which means it can increase the porosity of teeth enamel. Because of this the pigmented tea molecules are attached to the teeth easily, causing staining.

Prevention and Treatment

  • Add less sugar to your green tea.
  • Do not drink it multiple times a day.
  • Flossing is an effective preventive measure against teeth staining.
  • Brush your teeth twice a day with all natural whitening toothpaste.
  • If your teeth begin to discolor, make an appointment with a dentist as soon as possible.
  • Rinse your mouth with water after drinking green tea or any drinks that are likely to stain teeth.
  • Drinking with a straw would be the best for your teeth.
  • Consume foods such as milk, cheese, strawberries, papaya, pineapple, celery, carrot, apple, pear, citrus fruits, etc. They are known for whitening teeth naturally.
  • Opt for Oral Prophylaxis if possible. It is a procedure of removing plague, stain and calculus from teeth by scaling, polishing and cleaning.
