Since mouthwashes won't eliminate the problem, let's look at some possible reasons for the condition. Certain foods, such as onions, garlic, and spices will cause temporary bad breath. Some medical and systemic problems, such as sinusitis, can also contribute. But most causes are local in nature. Bacteria, plain and simple, are the culprit.
Bacteria do their work in the mouth, lungs, sinuses, and stomach.
In the oral cavity, bacteria cause gum disease. This infection is so prevalent today, it's the first dental problem we suspect when it comes to halitosis. With a thorough hygiene program, there is a chance to control gum problems and this particularly awkward side effect. For more information regarding bad breath, please call our office. Doc, it's just a back tooth.
