A cup of coffee might be the perfect thing to wake you up in the morning, but drinking it black can be incredibly damaging for your teeth. Teeth become stained by coffee owing to their porous nature. The inside of the tooth is solid and won’t be affected, but the outer surface absorbs the coffee and it stays there, coloring enamel and making your teeth appear darker.
It isn’t all bad news, though. You can still drink coffee without staining your teeth by simply adding a little milk to your mug. Not only does it make your coffee a cooler temperature for drinking, but you also get a little extra calcium to start your morning right and keep your teeth looking great and staying strong.
