Brushing to fight flu
Our mouths are home to 300 species of bacteria. Dr. Jon Hardinger, a dentist in Mason City, Iowa, says if your mouth is dry, saliva can't fight those germs and you're much more susceptible to a virus. "Reducing dryness is a good thing when you have a cold, that's why I recommend a glycerin based mouthwash," he said. It can also help get rid of the cold. Surprisingly gargling mouth wash can often work better than other cold medications.
