Rich, dark coffee can easily stain your teeth – just like other colorful foods and beverages, including red wine – if you drink it straight. Based on this, you might assume that coffee is bad for your teeth. If you look beyond the coffee stains (which can be removed with whitening toothpaste, by the way), it turns out that coffee is actually very good for your teeth! Researchers from Boston University discovered that drinking one or more cups of coffee each day can help product you from periodontal disease. Their study followed over 1000 men for more than 30 years and found that regular coffee drinkers had fewer teeth with bone loss (a sign of periodontal disease) than their non-coffee-drinking counterparts. They’re attributing this to the antioxidants in coffee, which may help to reduce gum and jaw inflammation. Researchers also point out that coffee is much less acidic than many other beverages, such as fruit juices, energy drinks and sodas, and regular coffee drinkers might also be selecting coffee over alternatives, rather than in addition to them.
