How to Tell if You Have Bad Breath

You have a white-coated tongue. This is a predictable sign of bad breath. "That white coating is comprised of sulfur compounds that have risen to the tongue's surface and cause bad breath," explains Levine. You have gastric reflux. The churning acid produced by gastric reflux is not only uncomfortable but can also lead to bad breath. "Unfortunately, gastric reflux results in bad breath in a way that's hard to solve," Levine says. "Ask your doctor about prescribing a medication to get this condition under control."
