Regarding effectiveness, the Philips Sonicare Prestige 9900 sets a new standard, largely thanks to its All-in-One brush head.

The universal nature of this brush head means you don't need multiple attachments for different oral care needs—it's a one-size-fits-all solution for cleaning, whitening, and gum care.
