What is the cause of halitosis, and what can be used to cure it?

Dentist, WebMD Medical Expert
American Academy of Cosmetic Dentistry

Halitosis or “bad breath” has a number of causes. Food odors, gum disease, tooth decay, stomach problems, sinus problems, and even certain diseases can all cause halitosis. The cures vary. To knock out any possible dental causes, I always advise my patients to have a good cleaning and examination, followed by a review of your at-home oral hygiene regimen. Your dentist can help you figure out the exact cause and treatment. Mouthwash can help, and some specialized rinses may also offer other benefits. For example, antibacterial rinses kill plaque-causing bacteria that can cause gingivitis, a mild form of gum disease.
