Why does my 12-year-old daughter always have bad breath?

Many possibilities: Cavities, bacterial buildup on her teeth, her diet, acid reflux, tonsil stones, and sinus infections all can contribute to halitosis. Seek treatment for these conditions with a local dentist and physician.

See a dentist: In the majority of cases, the cause of bad breath, or halitosis, is the product of bacteria in the mouth and gum disease. The proper diagnosis is the key to a successful treatment. See your dentist for Halimeter test, diagnosis and bad breath treatment that depends on its cause. Good luck.
