What is Green Tea?
What is Green Tea?

Before we discuss stains and sips, let us first understand what green tea is. Green tea is made from Camellia sinensis leaves and buds that undergo minimal oxidation during processing. With its origins in China, green tea is renowned for various benefits, such as its rich antioxidant properties and potential to enhance metabolic health.

The unique disposition of green tea, whether in its loose leaf or bagged form, begins with carefully picking its raw materials—namely, the “two leaves and a bud” of the tea plant. Once plucked, these young and tender parts undergo a process that halts oxidation, ensuring the leaves retain their natural greenness. These steps, which include withering, pan-firing or steaming, shaping, and drying, are meticulously orchestrated to preserve the tea's undeniable health properties.

Yes, green tea can and does stain your teeth, though perhaps to a lesser degree than black tea or coffee, the notorious dental culprit. The extent of staining can vary depending on many factors, such as the concentration of your brew, how frequently you drink it, and overall oral hygiene.

Tannins and the acidic nature of green tea are recognized as contributing factors to dental stains. Here how:

  • Tannins

    Tannins, a naturally occurring compound abundant in teas, boast astringent properties. They're responsible for the slightly bitter taste and the mouth-drying sensation when enjoying a strong cup of tea. This compound is also highly reactive with proteins. When these tannins mingle with the proteins in your saliva and on your teeth, they can create a film that clings to enamel, gradually contributing to discoloration over time.

  • Acidity

    The acidity of green tea, albeit less pronounced than coffee, still can temporarily soften your tooth enamel. This makes the teeth more susceptible to staining from other pigmented foods and drinks you might consume, as well as causing surface abrasions if brushing is done too soon after drinking.

Is Green Tea Less Likely to Stain Teeth than Black Tea?
Is Green Tea Less Likely to Stain Teeth than Black Tea?

Generally, yes. Black tea contains higher tannin levels than green tea because of the heightened oxidation process black tea leaves undergo. Tannins bind easily with the outer layer of your teeth, casting a yellow-brownish appearance over time. However, factors related to the quality of the tea and individual dental health practices can sway the degree of this observation.

Every coin has two sides, and so does our answer. Green tea is more likely to cause teeth staining than coffee. Green tea lovers can rejoice in the fact that coffee tends to stain teeth more than green tea, thanks to the varying colors and their effects on stain visibility.

Coffee's higher acid content and chromogens—the pigmented compounds found in dark-colored drinks and foods—are notorious for penetrating the microscopic ridges of your tooth enamel, making it the leading cause of dental discoloration.

Don’t they say, “Prevention is better than cure”? Following the saying, fortunately, you can mitigate the staining effects of green tea and other beverages.

  • Oral Hygiene

    Proper dental care serves as the primary defense mechanism for oral health. Regular brushing with whitening toothpaste, flossing, and rinsing with an antiseptic mouthwash can prevent stains from settling by removing the tannin and pigment residues.

  • Rinse or Brush

    Drinking a glass of water or swishing with mouthwash immediately after finishing your tea can help wash away the potential stains before they adhere to the teeth.

  • Limiting Exposure

    If you're a habitual sipper of green tea, especially concentrated varieties such as matcha, try to limit your teeth's exposure by sipping through a straw or brushing your teeth a while after, once the softened enamel has had time to harden again.

  • Professional Cleaning

    Frequent appointments with your dental hygienist can provide a fresh start, eliminating any discoloration that may have begun to appear.

  • Whitening Treatments

    For persistent stains, professional whitening treatments or over-the-counter options might be considered. Caution is advised when using these products, preferably with guidance from a dental professional. Improper use may lead to tooth sensitivity.

  • Dental Sealants

    For the green tea partisans who are mainly concerned with staining, dental sealants can be a longer-term solution. These thin plastic coatings applied to the back teeth act as saviors, making it tricky for stains to find a home on your enamel.


You know there's no need to feel guilty about your love for green tea or give up this soothing daily habit. Being mindful and proactive is vital to preserving the natural radiance of your smile. Simply indulge in your green tea and enjoy its variety of benefits.

You need not worry about these teeth stains if you are an irregular green tea drinker. So, does drinking green tea stain your teeth? Yes, it indeed does, especially if you are a regular green tea drinker. But with proper precautions, you can give green tea a green signal and keep your teeth as white as possible.
