A recent article in the New England Journal of Medicine highlighted an interesting case of a rare medical condition called "black hairy tongue." Unsurprisingly, the condition basically makes you look like you’ve got a black hairy tongue - hence the name. But, what causes this bizarre condition, and are you at risk?
Remember back in the day when getting a prescription for antibiotics for a cold was par for the course? Eventually, that practice slowed as bacteria became resistant to certain germs, rendering the antibiotics useless and paving the way for "superbugs" to thrive in those with weakened immune systems. Well, as it turns out, those antibiotics may do even more damage than initially thought. In addition to allowing the proliferation of superbugs, antibiotics have also been found to kill good bacteria - i.e., the bacteria we need in our mouths to help fight plaque and inflammation.
