How often should I replace my Philips Sonicare Brush Head?
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).
