How long does it take for a toothbrush to dry?

A toothbrush typically takes about 4 to 6 hours to dry completely after being rinsed and left out to air dry. Factors such as humidity and airflow can affect this drying time. To promote quicker drying, it's best to store the toothbrush in an upright position in a well-ventilated area. Additionally, avoiding covering the toothbrush can help prevent moisture buildup.
