Prevent coffee from staining your teeth

Coffee Staining: Mechanism, Prevention & Additional Science

Tooth enamel is the hardest substance in the human body but it's not completely smooth. Chemical and mechanical wear create microscopic cracks and roughness on the tooth's surface. These areas make great hiding-spots for the staining chemicals found in one of our favorite beverages – coffee.

Common Sources of Dental Wear and Tear

  • Charcoal toothpaste

  • Brushing teeth too hard

This toothbrush by OralB tells you when you are applying too much pressure on your teeth.

  • Toothpicks

  • Brushing right after eating or drinking

  • Using teeth to open or cut objects (ex: beer bottles)

Polyphenols in Coffee

Coffee contains something called polyphenols. Tannins are a type of polyphenol. Tannins bind to the outer layer of teeth. It is particularly hard to remove these tannins on a roughened tooth surface. If you don’t brush away the tannins daily, they stick to one another. Ultimately, the teeth look darker.

Prevent Staining

  • add milk to coffee: milk contains proteins that bind to tannins, preventing them from adhering to the tooth surface

  • choose coffee 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 straws limit beverage contact with your teeth and are great for the planet as well (this is my favorite straw set)

  • change your toothbrush or toothbrush head every 3 months

  • don't sip on sodas: if you are going to drink soda, consume in one sitting. Sipping all day keeps the mouth's pH really low. A low pH means more chemical wear of teeth.

  • try professional teeth whitening: this is my favorite option for at-home whitening White strips work for many people, but the results may not be as dramatic as those of professional teeth whitening by a dentist.
