What Causes Halitosis (Bad Breath)?

Sinus Problems

Getting sick can often be a cause of bad breath, particularly when the illness involves an individual's throat or sinuses. Congestion that comes in the form of nasal mucus or nasal drip can begin to create a consistent breeding ground for bacteria and germ growth, which can lead to halitosis. The best solution to combat the spread of further growth is for individuals to practice good oral hygiene even when, especially when, they are not feeling up to it. And once the illness has been cured, it is important to get a new toothbrush and not brush with the old one.
