(HealthDayNews) -- If you have bad breath, you've probably tried a collection of toothpastes, mouthwashes and all sorts of breath mints. And they may not have helped much.
Chronic halitosis is complicated. In some cases, bad breath calls for treatment from a dentist and an ear, nose and throat specialist together. In other cases, bad breath may be cleared up with a simple, over-the-counter antihistamine tablet.
When the department of pediatric dentistry at Tel-Aviv University in Ramat Aviv, Israel, studied halitosis in children, researchers found that one of the most common factors was postnasal drip. As reported in the Journal of Pediatrics, a mild antihistamine, just enough to stop the drip, may go a long way toward making your breath seem toothpaste fresh.
