If yоu cаn’t get rid оf а cоld, the flu, or а nagging sore throat, the reason may be your toothbrush. Studies at the University of Oklahoma Dental School have shown thatyour old toothbrush may carry the germs that are causing your illness. The studies have found that people who change their toothbrushes about every two weeks recover from common winter ills faster than people who use their toothbrushes for a month or more. Old toothbrushes can culture the germs that can cause colds, influenza, pneumonia, strep throat, diarrhea, and sinus disease. Another study found that disease germs can live in an unused toothbrush for as long as a week. They can start to thrive again every time you brush your teeth.
