Love Matcha? How to Prevent Teeth Stains and Keep Your Smile Bright

Every drink has a story, and matcha's is green. In recent years, this earthy, vibrant tea took off on social media, showing up in cafes and homes alike. Whether it's the flavor, that vibrant green color, or the little caffeine kick, matcha has quietly worked its way into people's daily routines.

But here's the thing: while it's a treat for your taste buds and a pop of color on your Instagram feed, it can also stain your teeth over time.

Think of this blog as your cheat code to matcha, why it stains your teeth, and what you can do to effectively prevent and remove discoloration.

What Is Matcha and Why Everyone’s Drinking It

The History of Matcha

According to Britannica, the origins of matcha date back to the 1100s in Japan, when a Zen Buddhist monk returning from China introduced the way of tea — the Japanese tradition of preparing and serving tea. This conventional practice highlights balance, honor, purity, and peace. It traditionally takes place in a tea house, a space separate from the host's main home, and involves specific utensils, mindful preparation, and the serving of desserts.

What’s in a Matcha Drink?

As noted by Harvard Health Publishing, matcha starts as leaves from the Camellia sinensis plant. Once harvested, they're steamed, stone-ground, and transformed into the vibrant green powder we know today.

Although matcha can be enjoyed on its own, many people prefer to mix it up — whether as whisked tea (usucha or koicha), a hot or iced matcha latte, or blended into smoothies, cocktails, and even pastries. How you prepare and enjoy matcha can actually alter its effects on your teeth.

Adding milk, sugar, or other ingredients can change how likely matcha is to stain your teeth. The pigments in matcha, along with naturally occurring tannins, can contribute to gradual discoloration over time.

Can Matcha Stain Your Teeth Like Coffee?

When it comes to staining your teeth, coffee tends to stain faster than matcha. Although tea is generally known to have a higher tannin content, coffee contains dark pigments and natural chromogens that easily cling to tooth enamel, making stains more noticeable. While matcha differs from regular green tea due to its bold green pigments, coffee remains the most obvious tooth stainer among the three.

Tea is also generally less acidic than coffee. According to Healthline drinks with a pH around 5.5 or higher are gentler on your enamel. Coffee usually sits a bit lower, between 4.85 and 5.10, while most teas range from 5 to 7. In other words, the less acidic your drink, the less it softens your enamel — meaning your teeth are less likely to pick up stains over time.

How Does Matcha Stain Your Teeth?

You're drinking the whole leaf

Because matcha is made from whole, finely ground tea leaves, unlike brewed green tea where the leaves are removed, matcha is consumed entirely — with the leaves suspended in the drink. This makes the pigments more concentrated and vibrant, which over time can contribute to tooth staining.

Add-ons can make it worse

Matcha lattes, cocktails, smoothies, and fizzes often include sweeteners, alcohol, or flavorful toppings. These add-ons can increase sugar levels or acidity, encouraging bacterial growth and weakening enamel — conditions that make teeth more prone to staining over time.

Tannins are still in the mix

Even though matcha stains teeth less than black tea due to its lower tannin content, lower acidity, and chlorophyll that helps manage oral bacteria, it can still cause staining.

Frequent sipping = constant exposure

Constant matcha consumption can stain teeth despite having fewer staining compounds than coffee and traditional tea. Drinking matcha daily — often cited as around four cups — may increase the risk of tooth discoloration.

How to Reduce the Stains Without Throwing Away Your Matcha Drink

Matcha's flavor and vibrant color make giving it up nearly impossible — but you don't have to. Here are 5 ways to enjoy it safely:

• Take a quick sip of water after enjoying matcha. Your saliva already helps clean your teeth, but rinsing with water gives pigments and acids a head start, keeping your smile brighter.
• Try to drink in moderation. Constant exposure gives pigments more time to settle on your teeth. If you're having numerous cups, balance it out with plenty of water to stay hydrated and reduce staining.
• Add milk or plant-based alternative. Milk proteins can attach to tannins, which may help reduce their staining potential.
• Use a straw when sipping matcha. It helps limit direct contact between the drink and your teeth, reducing exposure to staining pigments.
• Maintain good oral hygiene — and consider whitening products. Brushing and flossing every day help reduce bacterial buildup that can weaken enamel. Using an effective at-home teeth whitening system, such as a whitening kit or cleaning and whitening foam, can also help remove surface stains over time.
