No one likes to hear it, but it's worse not to know it: You have bad breath.
Bad breath (also known as halitosis or malodor) can be embarrassing and tough on those around you. Some people don't realize their breath could peel paint because people are afraid to tell them.
"Certainly bad breath can ruin relationships," says John Woodall, DDS, a dentist with Woodall and McNeill in Raleigh, N.C.
Fortunately, this problem is often easy to fix. What helps: Good oral hygiene, regular visits to your dentist, and ruling out any underlying conditions or other factors (such as some medications, diets, and foods) that could make your breath less than pleasant.
Bad breath is often caused by a buildup of bacteria in your mouth that causes inflammation and gives off noxious odors or gases that smell like sulfur -- or worse.
