Matcha Lattes: Are They Good
or Bad for Your Teeth?
Matcha lattes have become a fixture on café menus
across Camberwell and Kensington, prized for their
earthy flavour, natural energy boost and Instagram-
friendly green hue. But if you’re sipping one most
mornings, you might be wondering: is this drink doing
your teeth any favours, or quietly working against your
smile?
Here’s what the team at One Dental wants you to
know.
The Good News
Matcha is made from whole, ground green tea leaves,
which means it’s rich in catechins — natural
antioxidants with antibacterial properties. These
compounds may help fight the harmful bacteria in
your mouth that contribute to plaque and gum
disease. Matcha is also naturally lower in acidity than
coffee, so it’s gentler on tooth enamel, and it contains
fewer staining tannins than coffee or black tea.
So compared with your daily flat white, a matcha latte
is generally the friendlier option for your smile.
Where It Can Cause Problems
That said, matcha isn’t entirely risk-free:
Staining is still possible. Matcha’s chlorophyll and
tannins can settle into plaque and the natural
grooves of enamel, especially with frequent,
prolonged sipping.
Sugar and syrups matter more than the matcha
itself. Most café-bought matcha lattes include
added sugar, sweetened syrups or flavoured milk,
which feed the bacteria that cause tooth decay. A
plain, lightly sweetened matcha is a very different
drink to a syrup-heavy version.
Sipping slowly extends exposure. The longer the
drink lingers in contact with your teeth, the more
opportunity there is for pigments and sugars to
affect enamel and plaque.
Simple Tips to Protect Your Smile
- Use a straw for iced matcha lattes to reduce
contact with your front teeth. - Rinse with water after finishing your drink to wash
away lingering pigments and sugar. - Wait around 30 minutes before brushing —
brushing immediately after any acidic or
pigmented drink can wear down temporarily
softened enamel. - Choose less sweetened versions where possible,
and ask for reduced syrup. - Keep up regular brushing, flossing and hygiene
visits — this is what really determines whether
staining becomes a lasting issue.
The Bottom Line
Enjoyed in moderation, a matcha latte is a smile-
friendly alternative to coffee — but it’s not entirely
stain-proof, and the extras (sugar, syrup, frequency)
matter more than the matcha itself. Good daily habits
and regular check-ups are what keep your smile
bright, whatever you’re drinking.
