Coffee Staining: Mechanism, Prevention & Additional Science


While tooth enamel is the hardest substance in the human body, it is not smooth. Chemical and mechanical abrasion create microscopic cracks and roughness on the tooth over time. These spots make great hiding spots for staining chemicals found in one of our favourite beverages – coffeeeeee.

Common Causes of Abrasion

  • Charcoal toothpaste can create microscopic abrasion (other abrasive toothpaste can do this as well)

  • Brushing your teeth too hard

  • Drinking acidic drinks

  • Brushing right after drinking acidic drinks

Polyphenols in Coffee

Coffee contains polyphenols, specifically tannins, which bind to the outer layer of teeth. It is especially hard to remove these tannins on a roughened tooth surface. If you don’t brush away the tannins daily, they coagulate to form an increasingly dark stain. Yes, a lot of dentistry just comes down to brushing your teeth daily. The simple steps are the best steps.

Prevent Staining


Add milk to coffee: dairy and non-dairy milks contain protein which bind the tannins, preventing them from adhering to the tooth surface



Chooseenergy alternatives like matcha tea. Matcha tea is filled with antioxidants and is proven to be a more stable source of energy, without a caffeine high and crash.


Use a re-usable straw. Re-usable to help the environment and straw to prevent the coffee from ever touching your teeth


Regularly change your toothbrush so that you can clean effectively. Electric toothbrushes are great! They require little pressure and have timers built.


Avoid soda, sugary or acidic food consumption.


Get your teeth professionally whitened.White strips, mouthwashes, internet popularized items do work for some people but only modify the tooth shade mildly. A dentist can help reach a higher degree of whiteness in a safer and controlled space.
