NEVER leave your toothbrush in the bathroom

Keeping your toothbrush in the bathroom, especially near the toilet, can expose it to fecal particles and potential contamination. Bathrooms are humid environments that promote bacteria and mold growth on toothbrushes. Sharing a bathroom increases the risk of cross-contamination. To protect your toothbrush, rinse it before use, store it upright, invest in separate toothbrush holders, and replace it regularly.
