Coffee and green or black tea can stain teeth, especially if you consume them regularly. After years of tea or coffee consumption, teeth are often not white anymore. However, unlike other teas, Matcha does not cause teeth staining. Matcha consists of powder particles that are larger than the particles of other teas. When you whisk your matcha, it doesn't dissolve fully in the water. So, if you let your matcha sit still for a few minutes, the powder will sediment on the bottom of your chawan. Well, the teeth can´t absorb particles of matcha. And instead of harming the teeth, Matcha is actually good for them.
A study conducted by Harvard found that matcha green tea can have a significant positive impact on many parts of your oral wellbeing, from fighting tooth decay to reducing the likelihood of oral cancer.
The high content of catechin (EGCG) in Matcha is what is very interesting and beneficial for your teeth. These catechins have antibacterial effects, and in essence, they act as microscopic plaque scrubbers that can help prevent cavity formation and periodontal disease. The catechins in Matcha can also lower your mouth acidity and protect you from tooth decay.
We therefore think it is fair to argue that drinking Matcha is better than drinking a cup of corrosive coffee. In short, Matcha does not stain teeth, it cleans teeth, and can freshen your breath.
One more good reason to enjoy this fantastic tea!
