Toothbrushing & Cleaning Tools

How often should a toothbrush be replaced?

Short answer

A toothbrush or electric brush head should generally be replaced every three months, or sooner if the bristles start fraying, since worn bristles clean far less effectively. It should also be replaced after a cold or illness to avoid reintroducing bacteria.
