There are a few health conditions outside the mouth that can contribute to bad breath. Because dental problems are far more likely to be the culprit, we always rule them out first. If your dentist rules out any dental problems as the source of your bad breath, you then likely need to look outside the mouth.
A dentist will also examine your mouth for any signs of gum disease or other oral health issues that may be causing bad breath. They may recommend additional treatments or procedures to address these issues and improve your breath odor.

If your dentist determines that your mouth is healthy and that the odor is not oral in nature, you may be referred to your family physician or to a specialist to determine the cause of the odor and possible treatment. If the odor is due to gum disease, your dentist can either treat the disease or refer you to a periodontist, a specialist in treating gum tissues. Gum disease can cause gum tissues to pull away from the teeth and form pockets. When these pockets are deep, only a professional periodontal cleaning can remove the bacteria and plaque that accumulate.
