Sore Throats And Toothbrushes
Should you throw away your toothbrush after suffering from a cold or sore throat? This advice is based on the idea that the germs that caused the illness (like streptococcus) may remain on the toothbrush, potentially causing another bout of the illness later.
Interestingly, a recent study done at the University of Texas Medical Branch showed that the bacteria that causes strep throat failed to grow on all but one of the toothbrushes that were used for the study.
The study conducted was a small one, so the researchers have suggested that the results of a larger study would be more conclusive, and would be more likely to provide appropriate guidelines about whether our toothbrushes should be replaced after a sore throat.
