Keep brushing your best with BrushSync reminders

Keep brushing your best with BrushSync reminders

Did you know brush heads become less effective after three months? Dental professionals recommend changing your brush head regularly, that's why Philips Sonicare toothbrushes have BrushSync technology. It tracks how often and how hard you brush, then reminds you to replace your brush head once it's time for a new one.
