It is a fact that bad breath and allergies are interrelated and often one can be triggered or caused by the other.
The main culprit of halitosis is dry mouth. Dry mouth can cause bacteria to build up on the tongue and the more bacteria build up the stronger the bad breath. These ‘not so lovely’ bacteria feed on food remains and as they do they emit a foul smelling gas which is what causes the bad breath.
One of the most common factors that cause dry mouth is allergies. To make matters worse many of the medications given to treat allergies also cause dry mouth and therefore stronger bad breath. These medications often have an impact on your saliva production and actually cause a reduction in saliva produced. This causes your dry mouth and as a result there is less oxygen present which makes ideal conditions for bacteria to thrive.
