What is Green Tea?

Green tea is one of the healthiest types of tea consumed worldwide, with China being the major consumer. Black and Oolong teas are prominent in the United States, but green tea has gained appeal due to its health advantages and adaptability in blending diverse flavors.

Green tea’s popularity has been capitalized on by coffee shops, tea houses, and health food stores by developing mixes with berries, sweeteners, herbs, and other ingredients. 

Unlike black and Oolong teas, green tea is barely processed and retains its green color when steeped. It can be consumed hot for a refreshing sensation or sweetened and flavored to your taste for pleasure.

In short, the answer to the question “Does green tea stain your teeth?” is, yes it does. 

Green tea tends to stain teeth; however, the risk of tooth discoloration is not as severe as black tea or coffee. It is crucial to note that green tea can still cause gradual tooth discoloration over time.

Why Does Green Tea Stain Your Teeth?

So why does green tea stain your teeth?

Green tea includes tannins, which contribute to tooth discoloration. Consuming green tea on a regular basis increases the likelihood of staining, although infrequent consumption causes less noticeable discoloration.

The acidity in this beverage changes the pH balance in the mouth and gradually dissolves tooth enamel, allowing colored molecules to cling to the teeth. Green tea stains often have a drab gray tint, less noticeable than yellowish stains from other sources.

Green tea is definitely less acidic than black tea, which reduces the possibility of yellowish stains. 

Understanding these variables allows us to understand better how green tea can alter the appearance of our teeth.

pH Acidity Scale for Different Teas

Tea Average pH level
Black 4.9 – 5.5
Green 7-10
Chamomile, Mint, Fennel 6-7
Lemon 3
Rosehip, Blackberry 2-3

Black Tea Or Green Tea – Which is Worse for Your Teeth?

Both popular beverages, green and black tea, can cause teeth discoloration. However, whether there is a significant difference in how they stain teeth or if one is worse than the other is still being determined.

Based on observations, green tea appears to leave a gray stain, but black tea often leaves a yellow mark. Yellow stains may be more evident than gray ones since gray is essentially a blend of white and black, making it more difficult to spot at a glance. Yellow stains, on the other hand, can be more noticeable and catch the eye.

It is worth mentioning that some green teas may brew a brown hue, which indicates a higher tannin content. Teas with more tannins are likelier to stain teeth than lighter green teas.

Is it True That Green Tea Stains Your Teeth More Than Coffee?

Tea Stains Your Teeth More Than Coffee

Because of its tannins, green tea stains teeth more than coffee. On the other hand, coffee stains stand out due to their dark brown tone. The pH difference between green tea and coffee also contributes to color variation. 

In conclusion, while green tea has a more considerable staining potential than coffee, the resulting stains are often less noticeable.

Which Tea Does Not Stain Teeth?

While no tea will not stain your teeth, some teas will stain your teeth more than others. White tea and oolong tea, for example, have lower tannin levels than other forms of tea. As a result, they are less likely to stain. If you’re worried about stains, lower-staining teas might be a good solution for you.

Furthermore, green teas that have been steamed or roasted are less likely to stain. These green teas go through a process that decreases the number of tannins present. These are wonderful options if you are looking for green tea that won’t stain your teeth.

How to Prevent Green Tea From Staining Your Teeth?

Rinse Your Mouth After Drinking Green Tea

After drinking green tea, thoroughly rinse your mouth. This easy action aids in removing acidic chemicals that may have accumulated around your teeth, lowering the possibility of discoloration.

Brush Your Teeth

Brush your teeth each time after drinking green tea, if feasible. Brushing removes any remaining tea residue and keeps your mouth fresh and clean.

Floss Regularly

Dentists recommend flossing daily to prevent tooth darkening and discoloration caused by green tea. Flossing can also help keep your gums healthy and firm. It should be a regular part of your dental hygiene routine.

Whitening Toothpaste

Include whitening toothpaste in your brushing routine to help keep your smile bright. These toothpastes can help reduce green tea stains and create a whiter appearance over time.

Use an Electric or Ultrasonic Toothbrush

Research shows these toothbrushes are more successful than manual brushes at cleaning teeth and gums. Improve your dental hygiene by switching to an electric toothbrush.

Use a Straw

When sipping tea, use a straw to reduce direct contact between the tea and your teeth. This approach effectively prevents stains on the front upper and lower teeth. Remember, though, that it may be less helpful for the rear teeth. This method can also be used when drinking soda.

Professional Teeth Whitening

If you drink green tea frequently and have stains on your teeth, professional teeth whitening may be an option to investigate. A dental professional can perform oral prevention, a comprehensive teeth-cleaning process that efficiently removes green tea staining. This therapy is typically prescribed once every six months and is conducted in a single session.


Implementing these easy measures will drastically prevent tea staining and help you keep your smile looking young and bright. By following the above guidelines, you may help maintain your teeth looking their best and reduce the possibility of discoloration.
