Allergies Could Be Causing Your Bad Breath

If you find that your sniffling, sneezing and runny eyes are accompanied by mouth odor, you’re not alone; seasonal allergies are associated with halitosis, or bad breath.

Bad breath is caused by the same destructive bacteria that cause plaque and gum disease. They live in the mouth, where they feed on carbohydrates consumed as food. In a healthy mouth, these bacteria are kept in check by saliva production. Saliva washes away the bacteria, so they have less time to stick to teeth, eat sugar and emit smelly gas as a byproduct.
