Bad breath, also called halitosis, can be embarrassing and in some cases may even cause anxiety. It’s no wonder that store shelves are overflowing with gum, mints, mouthwashes and other products to fight bad breath. But many of these products are only short-term measures. That’s because they don’t address the cause of the problem.
Certain foods, health conditions and habits are among the causes of bad breath. In many cases, you can make bad breath better by keeping your mouth and teeth clean. If you can’t solve bad breath yourself, see your dentist or another healthcare professional to be sure a more serious condition isn’t causing it.
Symptoms
Bad breath odors vary, depending on the cause. Some people worry too much about their breath even though they have little or no mouth odor. Others have bad breath and don’t know it. Because it’s hard to know how your breath smells, ask a close friend or relative to confirm if you have bad breath.

When to see a doctor
If you have bad breath, review how you keep your mouth and teeth clean. Try making lifestyle changes, such as brushing your teeth and tongue after eating, using dental floss, and drinking plenty of water.

If you still have bad breath after making changes, see your dentist. If your dentist thinks a more serious condition is causing your bad breath, you may need to see another healthcare professional to find the cause of the odor.
