How do you know when to replace a toothbrush head?
You should replace your brush head every three to four months or sooner if you notice the bristles becoming frayed and worn. Many models also feature indicator bristles that fade in color to signal that the cleaning technology is no longer at its peak performance.
Can I use a toothbrush head for longer than 3 months?
While you can physically use it longer, worn bristles lose their effectiveness and remove significantly less plaque than a fresh brush head. Clinical research suggests that a new brush head is necessary to ensure you are getting the most effective clean for your teeth and gums.
Does the Oral-B app remind me to change my brush head?
The app tracks your actual brushing time and provides a helpful notification when it is time to swap for a new refill. This smart feature takes the guesswork out of maintenance and ensures you always have the most advanced cleaning power available.
