The Truth About Bad Breath: What Causes It and How to Fix It

Bad breath, also known as halitosis, is something nearly everyone experiences from time to time. Whether it's first thing in the morning or after eating certain foods, occasional bad breath is completely normal. But if it persists throughout the day—even after brushing your teeth—it may be a sign that something more is going on. In fact, studies estimate that about 1 in 4 people worldwide experience chronic bad breath. While it can be embarrassing, the good news is that it's often treatable once the underlying cause is identified.
