Worried about bad breath? The American Dental Association [1] has online answers to questions and concerns about halitosis.

Dental experts say bad breath may be linked to something more serious than poor oral [2] hygiene. It could be linked to dry mouth caused by a sinus infection, postnasal drip or linked to a respiratory [3] tract infection.

If you are suffering from chronic bad breath, a dental visit may be in order to determine the cause. The best defense being a good offense, a regimen of oral [2] hygiene should be the first consideration.

Most dentists are trained in diagnosing bad breath, but if the origin is not dental-related you will most likely be referred to your family physician.
