How often should you replace your toothbrush?
Replace toothbrushes every 3 to 4 months. Consider getting a new toothbrush sooner if you have been sick, especially if the toothbrush is stored close to other toothbrushes.
Many dental professionals recommend changing your toothbrush about every three months, and the American Dental Association (ADA) recommends that you replace your toothbrush approximately every three to four months, or sooner if the bristles are frayed.
