Matcha also provides numerous oral health benefits. Studies have shown its high catechin content, particularly EGCG (Epigallocatechin gallate), which effectively combats harmful oral bacteria, reduces inflammation and may prevent periodontal diseases like gum disease and tooth decay.

Chlorophyll in matcha not only helps detoxify but also neutralizes bad breath, and its fluoride content aids in strengthening tooth enamel, making it more resistant to decay from acidic foods and bacteria.

However, many people are concerned about the impact on teeth that this team might have. The stains.

Let’s explore whether there is a real reason to worry about stains from matcha and what steps might help keep your teeth bright while enjoying this popular drink.

Is There a Reason to Worry?

Unlike coffee or black tea, which contain high levels of tannins that cling to enamel and cause lasting discoloration, matcha has a different composition. Its color stems from chlorophyll, a natural pigment that, in most cases, doesn’t cause a deep stain. Any slight tint tends to affect plaque buildup rather than the enamel itself.

For those who drink matcha regularly, simple steps like rinsing with water after drinking, brushing, and flossing effectively remove any potential tint left on plaque. Good oral hygiene helps prevent this temporary coloring from becoming visible, making matcha a more tooth-friendly option than other dark-colored drinks.

In short, matcha does not lead to the kind of permanent staining common with darker drinks.

But What About the Chlorophile and Other Pigments?

Chlorophile may leave a temporary tint on plaque but does not bond to enamel in the same way as darker, tannin-heavy drinks.

For those who enjoy matcha often, a consistent brushing and flossing routine effectively prevents any discoloration. Removing plaque keeps any possible tint from becoming visible, so you can continue enjoying matcha with confidence that your teeth will stay bright.

“Chlorophyll, the green pigment in plants, can cause surface stains on teeth when consumed in liquid form. These stains are extrinsic, meaning they only affect the surface and can be easily removed through regular brushing, flossing, and dental cleanings.” – Dr. Brian Harris

Let’s Compare It to Coffee and Black Tea

Beverage Primary Staining Agent Stain Intensity Effect on Enamel Best Practices for Prevention
Matcha Chlorophyll Low Temporary tint on plaque, not enamel Rinse with water, brush, floss regularly
Coffee Tannins High Deep stains that penetrate enamel Brush after drinking, consider whitening treatments
Black Tea Tannins High Strong yellow stains that bond with enamel Use a straw, rinse with water, avoid excessive intake

Additional Tips

  • Rinse with Water: After drinking any of these beverages, rinsing with water helps wash away pigments that might settle on teeth.
  • Use a Straw: For iced drinks, using a straw reduces contact between the liquid and teeth, minimizing staining potential.
  • Brush and Floss Regularly: Brushing and flossing help remove plaque where pigments can cling, especially useful after drinking matcha.
  • Consider Whitening Treatments: For coffee or tea drinkers with existing stains, professional whitening treatments can help restore brightness.

Ways to Prevent Stains on Teeth

Although there is a low risk of causing stains compared to other dark beverages, taking extra care can keep teeth bright and free of any potential green tint.

1. Rinse with Water After Drinking

Simply rinsing your mouth with water immediately after drinking matcha helps wash away any pigments before they can settle on plaque. This easy step reduces any slight tint that might otherwise remain.

2. Brush and Floss Regularly

Maintaining an oral hygiene routine of brushing and flossing twice a day keeps plaque buildup minimal, which prevents pigments from sticking to the teeth. Brushing within 30 minutes of drinking matcha is especially effective for clearing any residue before it can be set.

3. Drink Through a Straw

For cold matcha drinks, using a straw minimizes direct contact with teeth, reducing the risk of pigments settling on plaque. This practice is particularly useful for those who enjoy matcha often or in iced form.

4. Add Milk to Your Matcha

Adding milk, especially dairy or plant-based milk with casein, can reduce staining. Casein binds with tannins and pigments, which prevents them from clinging to the teeth as easily.

5. Use Whitening Toothpaste

Whitening toothpaste can help maintain a bright smile and remove surface stains that might build up from various foods and drinks, including matcha.

6. Visit the Dentist Regularly

Regular dental cleanings are effective for removing any minor stains or plaque buildup, ensuring teeth stay bright and healthy.
