Time to buy a new toothbrush?

Medically reviewed on May 3, 2018.

Invest in a new toothbrush or a replacement head for your electric or battery-operated toothbrush every three to four months. Change it sooner if the bristles become irregular or frayed. Keeping a toothbrush for too long makes it difficult to clean your teeth well.
