Charcoal toothbrush bacteria showdown: which brush is cleaner?

This study compared bacteria on charcoal-infused toothbrushes versus standard nylon ones. 36 healthy adults and children used each brush for one day and one week, then returned them for lab testing. Researchers counted the bacteria to see if charcoal bristles stay cleaner. The goal was to find out if eco-friendly charcoal toothbrushes are a more sanitary option for daily oral care.
