You may enjoy the unique flavour and health benefits of matcha. This vibrant green tea is a popular choice for a morning boost or an afternoon treat, as it contains antioxidants that can support your oral health.
But what about that bright green colour and your smile? While matcha can contribute to surface stains on your teeth over time, its effect largely depends on your dental hygiene habits and other factors. Understanding how it interacts with your teeth can help you enjoy your favourite drink without worry.
The Truth About Matcha & Your Smile
You may love the vibrant green colour and unique taste of matcha, but it’s fair to wonder about its effect on your teeth. The answer isn’t a simple yes or no, as it involves a few different factors. While matcha contains natural compounds that can lead to stains, the impact on your smile is often manageable.
A Look at Tannins & Chlorophyll
Matcha gets its famous green hue from chlorophyll, the same pigment that gives plants their colour. It also contains compounds called tannins, which are found in many teas, berries, and even red wine. Both of these substances can stick to your tooth enamel, which may cause slight discolouration with frequent consumption.
The Role of Dental Plaque
Interestingly, matcha pigments often cling more to dental plaque than to the enamel itself. Plaque is a soft, sticky film of bacteria that forms on your teeth. When matcha stains this film, your regular brushing and flossing routine can help remove it before it becomes a long-term issue.
Matcha vs. Coffee: A Stain Comparison
Many people compare matcha to coffee when it comes to teeth stains. Both beverages contain compounds that can discolour teeth, but they interact with your smile a bit differently. Your daily habits and dental care play a much larger role in staining than the choice between one drink or the other.
How Their Pigments Differ
Coffee has dark, acidic pigments that are well-known for causing yellow or brown stains over time. Matcha’s green pigments from chlorophyll are generally less intense and can be easier to manage. However, because matcha is a fine powder, its tiny particles can sometimes settle into the natural grooves of your tooth enamel.
Habits Matter More Than the Drink
Neither beverage is necessarily worse for your teeth—it all comes down to frequency and your oral hygiene. How much you drink and how you care for your teeth afterward are the most important factors. A consistent routine makes the biggest difference, no matter your preferred morning drink.
How to Enjoy Matcha & Keep Your Teeth Bright
You don’t have to give up your favourite green tea to maintain a bright smile. With a few simple habits, you can easily manage and prevent potential stains from building up. A proactive approach allows you to enjoy matcha worry-free.
Brush Your Teeth After Matcha
Brushing your teeth about 30 to 60 minutes after drinking matcha is a great practice. This short wait gives your enamel time to reharden if it was temporarily softened by the drink. If you can’t brush right away, even a simple rinse with plain water can help wash away the loose green pigments.
5 Simple Tips for a Stain-Free Smile
Small changes to your routine can make a big impact on keeping your teeth bright.
- Rinse With Water: After you finish your matcha, swish some water around in your mouth to rinse away any leftover residue.
- Use a Straw: Drinking iced matcha through a straw helps the liquid bypass your front teeth, limiting direct contact.
- Eat Crunchy Foods: Munching on crisp foods like apples, celery, or carrots after your drink can help scrub your teeth naturally.
- Don’t Skip Floss: Flossing daily is important for removing plaque and food particles from between teeth, where stains can easily build up.
- Schedule Regular Cleanings: Professional cleanings are key for removing surface stains that brushing alone can’t handle. A visit to your twice a year helps keep your smile healthy.
Should You Drink Matcha After Teeth Whitening?
If you are undergoing a professional teeth whitening treatment, it’s a good idea to limit or avoid drinks like matcha and coffee. Your teeth can be more susceptible to staining right after a whitening session. Sticking to water for a short time helps you get the most out of your treatment.

What About Matcha Lattes & Sweeteners?
How you prepare your matcha matters for your oral health. While pure matcha has a number of benefits, adding milk, sugar, or flavoured syrups changes its effect on your teeth. These additions can unfortunately counteract the positive aspects of the tea itself.
How Additives Change the Equation
Sugar is a primary food source for the harmful bacteria in your mouth that produce acid and cause cavities. Adding sweeteners to your matcha latte can increase your risk of tooth decay. While a splash of milk can sometimes reduce staining from tannins, the added sugars in many cafe-style drinks are a bigger concern for your dental health.
What Stains Might Reveal About Your Oral Health
Sometimes, how easily your teeth stain can be a sign of your overall dental health. If you notice that matcha or other foods are causing discolouration very quickly, it might be worth a closer look. A bright smile always starts with healthy teeth and strong gums.
A Sign to Check Your Enamel
Enamel is the hard, protective outer layer of your teeth. If your enamel is weak, worn, or has microscopic grooves, it can absorb pigments more easily. Heavy staining could be a hint that your enamel needs some attention from a dental professional during your next checkup.
