Replace your toothbrush!

A study from researchers at the University of Manchester found that “the average toothbrush can contain 10 million or more bacteria,” including E.coli and Staph. The article reports that the study illuminates the importance of properly rinsing and storing one’s toothbrush, as well as replacing it at the proper interval.  To reduce the amount of bacteria, people should rinse their brush thoroughly after use, replace it when the bristles become frayed or after three months of use, and to store it in an upright position “in a spot that gets enough air for it to dry between brushings.”
