    How often should I replace my Philips Sonicare Brush Head

    It is recommended to replace your Philips Sonicare Brush Head every three months of normal use (brushing twice a day) or when the blue indicator bristles wear out. One reason is because brush heads can get weary and will be less effective in removing plague. 

    Note: Some Philips Sonicare toothbrushes have a brush head reminder feature. The replacement icon on the handle will start to flash when it's time to replace your brush head. You can expect the reminder to come up approximately every three months of normal use (brushing twice a day for about 2 minutes).

    If none of these tips solved your issue then please contact us or try our troubleshoot assistant (US only) for further support.
