Does green tea stain your teeth?
Green tea does have the potential to discolor your teeth. Although the risk of tooth discoloration isn't quite as high as it is with black tea, green tea is also known to stain teeth over time.
Why does green tea stain your teeth?
Green tea (along with other teas and beverages such as coffee) can discolor teeth and gums. There are two main components found in green tea that are primarily to blame for staining teeth. These two ingredients are tannins and acids.
Let's begin with tannins, which are the components in tea that make it more likely to discolor teeth.
This also implies that, depending on how frequently you drink green tea daily, the risk of staining your teeth increases. Drinking a cup of green tea once every two days or less is unlikely to discolor your teeth. But if you have heavy consumption, you may notice the green tea staining on your teeth.
But there’s another side to it:
The acidity of the tea leads to a change in the pH balance in the mouth. This acidity level will erode your teeth’ enamel. When enamel is destroyed, colored particles may settle and adhere to your teeth more quickly. This process takes time and a lot of green tea, but that's how green tea causes tooth discoloration.
Because green tea has lower acidic content, the stains appear dull gray and are less noticeable when compared to black tea's yellow tooth stains. The pH scale ranges from 7 to 10. That's why it causes a gray stain rather than a yellow stain and is less prone to causing tooth discoloration among infrequent green tea drinkers.
Tips on how to prevent tooth stains from green tea
There are a few things you can do to prevent your teeth from staining from drinking tea.
- Rinse your mouth. After a cup of green tea, rinse your mouth thoroughly. This will, to a considerable degree, rinse away most of the acidic substances that have gathered around your teeth.
- Brush your teeth. If it's convenient, brush your teeth after a cup of green tea.
- Flossing. Many dentists recommend flossing daily. Daily flossing will not only assist in avoiding tooth darkening and discoloration caused by green tea, but it will also keep gums firm and healthy.
- Whitening toothpaste. Brush your teeth with teeth whitening toothpaste to maintain a whiter smile.
- Ultrasonic toothbrush. Use an electric or ultrasonic toothbrush. According to the conclusions of a new study, electric toothbrushes clean teeth and gums much better than manual toothbrushes.
- Use a straw. The purpose of using a straw to sip tea is to bring the tea to your mouth while not having contact with your teeth. This works well for preventing stains on your front upper and lower teeth, but it does nothing for your back teeth. It also works well for soda.
- Professional teeth whitening. If you consume a lot of green tea and have stains on your teeth, you might consider professional teeth whitening. Oral prophylaxis is a teeth-cleaning method that many individuals use to remove the green tea discoloration from their teeth. In most cases, this is done once every six months in a single session.
Yes, green tea can leave a grey stain on your teeth. However, it will not be as noticeable as the yellow stains caused by green tea, or the yellow stains caused by turmeric tea.
A professional teeth whitening performed by a dentist will be the quickest way to remove green tea teeth stains. The disadvantage of using professional treatments to avoid tooth staining from green tea is that you'll have to see the dentist around once every six months or so, which may add up the expenses. So, after a cup of green tea, follow the advice above.
