Yes, a symptom of dry mouth (xerostomia) could be bad breath. Dry mouth happens when there is not enough saliva to keep the mouth wet. Bad breath can occur because one of the functions of saliva is to keep germs like bacteria and fungus in check. This is also why dry mouth can increase the risk for tooth decay. References 1.
