Halitosis is another word for “bad breath”.  The most common cause is bacteria.  Because the mouth is moist and warm, it creates perfect conditions for the millions of bacteria that live in the mouth.  In fact, approximately 80% of bad breath is caused by something in the mouth.

Some types of bad breath, such as "morning mouth," are considered fairly normal and are not usually health concerns. However, persistent bad breath may be a sign of more serious problems.

Bad breath may be caused by the following:

  • Poor dental hygiene
  • Infections in the mouth such as periodontal (gum) disease
  • Foods such as garlic, onions, and coffee, as well as cigarettes and chewing tobacco
  • Salivary gland problems or breathing through the mouth
  • Illnesses such as diabetes, liver disease, kidney disease, lung disease, sinus disease, reflux disease, respiratory-tract infections, throat infections, sinus infections

Call our office promptly if you have bad breath with painful, swollen gums that bleed easily or loose teeth.
