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.

This is like a mini dental hygenist robot

This is the best toothbrush ever. My teeth literally feel like I just got up from a professional dental cleaning every time I use it. I have sensitive teeth and gums. My tooth sensitivity has lessened since I switched from the Sonicare sensitive toothbrush head to this one. I use a lighter touch with this one to avoid it being too hard on my gums.

Pros

Unbelievably clean teeth every time

Verified buyer

noticeably cleaner teeth

I am impressed with how noticeably cleaner my teeth felt after using the A3 Premium brush head compared to the version the toothbrush comes with. My wife said the same thing after her first time trying those A3s.
