The average lifespan of an Oral-B electric toothbrush and its charger is approximately 3-5 years, depending on the model and the whether the toothbrush has been used as intended.
Most dental professionals recommend changing your toothbrush or brush head every 90 days or sooner if you brush more than twice daily or longer than 2 minutes. Several Oral-B brush heads feature indicator bristles which change color from green to yellow to signal when it’s time for a replacement.
All of our rechargeable toothbrushes come with a 2 year warranty.
