ExpDailyWhite Superior Clean Replacement Brush Heads, 8 Pack @ Amazon

SUPERIOR CLEANING - Powerful sonic wave transmission technology coupled with 3D cut bristles that conform to the shape of your teeth, removing up to 10 times more plaque in hard-to-reach areas.

SHOCK-ABSORBING DESIGN - The brush head is wrapped in a layer of air-cushioned soft silicone that absorbs the impact and allows it to gently touch your teeth and gums without jarring or numbing your teeth, improving the comfort of brushing.

GENTLE AND EFFECTIVE - 20% more surface area for brush head and implant bristles to clean up to 4 teeth at a time. Medium soft DuPont bristles with rounded ends to prevent damage to teeth and gums.

NO GUESSING WHEN TO REPLACE - Blue reminds the bristles will slowly fade in color and when the color fades about a third of the way down, it's a reminder that it's time for a new brush head for optimal cleaning results. (Typically three months)

PERFECTLY COMPATIBLE - Toothbrush head designed for Philips Sonicare. Compatible with all Philips Sonicare snap-on electric toothbrushes.(Not compatible with screw-in brush handles Advance, Essence, Elite, CleanCare, Xtreme and One Series.)
