If you have a desire to stain your teeth, consuming multiple cups of coffee a day is a sure way to get you there. That much you likely already know. What you may not know, though, is that drinking coffee in moderation can actually help you protect your teeth, because of coffee’s unique anti-bacterial properties. And, coffee isn’t alone in this regard. Tea, too, has some pretty marvelous properties, despite its propensity to stain teeth as well!
Trigonelline is what’s known as an alkaloid. And this alkaloid appears to be of specific benefit to our teeth. It’s found in its highest levels in Arabica coffee beans, and research suggests it interferes with cavity-causing bacteria’s ability to adhere itself to tooth enamel. Research is ongoing, but it does seem to be another feather-in-the-cap of your morning “joe.”
