Bad breath odors vary, depending on the source or the underlying cause. Some people worry too much about their breath even though they have little or no mouth odor, while others have bad breath and don’t know it. Because it’s difficult to assess how your own breath smells, ask a close friend or relative to confirm your bad-breath questions.
Bad Breath is medically called halitosis which can result from poor dental health habits and may be a sign of other health problems. It can also be made worse by the types of foods you eat and other unhealthy lifestyle habits.
Most bad breath starts in your mouth, and there are many possible causes. They include:
Poor Dental Hygiene
The most common cause of bad breath is poor oral hygiene. Bacteria that build up on your teeth – particularly between them – as well as your tongue and gums, can produce unpleasant-smelling gases. These bacteria are also responsible for gum disease and tooth decay. If you don’t floss and brush your teeth regularly, any food trapped between your teeth will be broken down by the bacteria and may be responsible for bad breath.
Bacteria can also live on the rough surface of your tongue. As well as brushing your teeth, cleaning your tongue can also help control bad breath.
The breakdown of food particles in and around your teeth can increase bacteria and cause a foul odor. Eating certain foods, such as onions, garlic and spices, also can cause bad breath. After you digest these foods, they enter your bloodstream, are carried to your lungs and affect your breath.
After eating food with strong odors like garlic, brushing and flossing even mouthwash merely covers up the odor temporarily. The odor will not go away completely until the foods have passed through your body.
Saliva helps cleanse your mouth, removing particles that cause bad odors. A condition called dry mouth or xerostomia can contribute to bad breath because production of saliva is decreased. Dry mouth naturally occurs during sleep, leading to “morning breath,” and it worsens if you sleep with your mouth open. Chronic dry mouth can be caused by a problem with your salivary glands and some diseases.
Smoking is another cause of bad breath. As well as making your breath smell, smoking stains your teeth, irritates your gums, and reduces your sense of taste.
It can also significantly affect the development of gum disease, another major cause of bad breath. Stopping smoking will lower your risk of gum disease and help prevent bad breath.
Crash dieting, fasting, and low-carbohydrate diets are another possible cause of bad breath. They cause the body to break down fat, which produces chemicals called ketones that can be smelled on your breath.
Some medications can indirectly produce bad breath by contributing to dry mouth. Others can be broken down in the body to release chemicals that can be carried on your breath.
Infection in the mouth
Bad breath can be caused by surgical wounds after oral surgery, such as tooth removal, or as a result of tooth decay, gum disease or mouth sores.
When to see a Doctor
If you have bad breath, review your oral hygiene habits. Try making lifestyle changes, such as brushing your teeth and tongue after eating, using dental floss, and drinking plenty of water.
If your bad breath persists after making such changes, see your dentist. If your dentist suspects a more serious condition is causing your bad breath, he or she may refer you to a physician to find the cause of the odor.
