Green tea is often lauded for its incredible ability to work for the benefit of overall health, but does it do more bad than good when it comes to your mouth? If you can spot enamel staining from afar, excessive usage of this beverage might just be the culprit. But how does green tea stain your teeth? Let’s find out.

The Reason Behind Green Tea Staining Teeth

This infamous beverage has tannins that are naturally occurring compounds, bitter in taste, and the reason why green tea leaves a stain on your teeth. Tannins work to taint your teeth by attracting enzymes, carbs, sugars, and proteins to the teeth; all of these substances are responsible for the discoloration of your enamel.

Other Types of Teas That Stain Teeth

Like most herbal green teas, the black counterpart also has tannins that make your teeth lose their color over time. While you can expect a gray hue from green, black tea make your teeth yellow. Black tea stains teeth worse than coffee because black has a higher tannin content than coffee and green tea.

Other than green and black teas, we have fruit variants as well. They contain tannins and acidic properties of fruit that work to destroy tooth enamel. It is often kept in the mouth longer than regular tea because of its pleasant taste and thus increased level of destruction.

Which Variant Does Not Cause Significant Teeth Staining?

  • White Tea
    White tea does contain tannins like others, but the stains are light in color, making them less noticeable at a glance.
  • Peppermint Tea
    Peppermint is the best and rarest version of tea that includes comparatively fewer tannins. You know what that means; unless you consume peppermint tea in significantly higher quantities, there are very less chances of visible teeth staining.

5 Ways to Prevent Teeth Stains from Green Tea

We understand your concerns if you are a regular user and are worried about the aesthetics of your pearly whites. There is no need to bar yourself from having even a cup. Fortunately, the dental world has multiple ways to help you maintain your beautiful smile.

  1. Regular Dental Cleanings and Exams
    Perhaps the best action you can take to remedy this issue is by scheduling bi-annual professional teeth cleaning. Dentists have all the right tools and expertise to remove short-term tooth staining from drinking green tea and coffee.
  2. Teeth Whitening Treatment
    Professional teeth whitening can remove deep teeth stains and restore your smile to its perfect form. This route is best for long-term staining that routine teeth-cleaning regimes cannot fix.
  3. Wait 30 Minutes to Eat After Brushing
    It is a general rule of thumb to avoid drinking any beverages like green tea for 30 minutes after brushing your teeth. This is because the fluid washes away fluoride from your toothpaste before it has the chance to do its job.
  4. Use a Straw to Drink
    Although it is a task to do with hot tea, consider drinking your iced green tea through a straw so that it does not come in contact with enamel and cause stains.
  5. Rinse Mouth Thoroughly After
    Tannins sit on the enamel and attract compounds that leave stains on it. Therefore, rinsing your mouth after drinking tea is a good way to cut down on their mode of action. The water takes away any residue on the enamel with itself.

Closing Note

So, if you are an avid green tea drinker, think about ways you can fix the stain problem on your teeth. The best way to move forward is to go for a teeth whitening session followed by bi-annual dental cleaning.
