I suffer from awful halitosis after consuming even a small amount of sugar (even natural sugars in fruit juices). What can I do?

Halitosis. Halitosis can result from: acid reflux, decayed teeth, infected gums, infections or diseases of the mouth and throat, poor oral hygiene, diet, stomach or intestinal issues. Make an appointment with your dentist for a thorough exam, dental cleaning, and oral hygiene instructions. If there are no dental issues, see your medical doctor for an examination.
