What causes bad breath?
Food. What you eat affects the air you exhale, like garlic or onions. If you don't
brush and floss daily, particles of food can remain in the mouth, collecting bacteria,
which can cause bad breath. Dieters may develop unpleasant breath from infrequent
eating.
Gum disease. Persistent bad breath or a bad taste in the mouth can also be one of
the warning signs of gum disease; which is caused by plaque.
Dry mouth. This occurs when the flow of saliva decreases and can be caused by various
medications, salivary gland problems or continuously breathing through the mouth.
Without enough saliva, food particles are not cleaned away. If you suffer from dry
mouth, your dentist may prescribe an artificial saliva, or suggest using sugarless
candy or increase your fluid intake.
Smoking and tobacco. In addition to staining teeth and being bad for overall health,
tobacco can add to bad breath. Tobacco reduces your ability to taste foods and irritates
gum tissues. Tobacco users are more likely to suffer from gum disease and are at
greater risk for developing oral cancer. If you use tobacco, ask your dentist for
tips on kicking the habit.
Medical conditions. Some diseases have symptoms related to bad breath. Sinus or
lung infections, bronchitis, diabetes, and some liver or kidney diseases may be
associated with bad breath
Maintaining good oral hygiene, eliminating gum disease and scheduling regular professional
cleanings are essential to reducing bad breath.
The IDA recommends that you brush twice a day and clean between your teeth daily
with floss. Brush your tongue, too. If you wear dentures, be sure to remove them
at night and clean them thoroughly before replacing them the next morning.
It’s important to note that mouthwash will only mask the odor temporarily.
Mouthwashes do not have a long-lasting effect on bad breath. If you must constantly
use a breath freshener to hide unpleasant mouth odor, see your dentist.
