WHEN TO CHANGE YOUR TOOTHBRUSH OR BRUSH HEAD
How Often Should You Change Your Toothbrush or Electric Toothbrush Head?
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.
That's because, no matter what type of toothbrush you use, its bristles can become frayed and worn and may lose their effectiveness. And clinical research shows that a new toothbrush can remove more plaque than one that's worn out, ensuring that your brush is working its hardest to help keep your teeth clean and healthy.
