Oral-B FlossAction Replacement Brush Heads, 5-Count Refill — Round Floss-Like Bristles for Interdental Plaque

Oral-B FlossAction replacement brush heads are round, dentist-inspired electric toothbrush refills with floss-like bristles that help remove plaque between teeth.

These genuine Oral-B FlossAction brush head refills are designed for use with most Oral-B rechargeable handles (excluding Oral-B sonic and iO models). Each round head targets individual teeth with a combination of unique floss-action bristles and indicator bristles that fade to signal when it’s time for a replacement. Packaged as a 5-count refill set, they offer multiple months of regular use and make it easy to keep a fresh brush head on hand.

How do FlossAction bristles work to clean between teeth?

The FlossAction design uses fine, flexible bristles that reach into interdental spaces to loosen and lift plaque where standard bristles may miss. The round head rotates and oscillates with compatible power handles to access tooth-by-tooth surfaces.

• Specialized bristles angle into tight spaces between teeth
• Round, compact head follows each tooth for targeted cleaning
• Engineered for use with Oral-B rotary/oscillating handles

When should I replace each replacement brush head?

Each FlossAction head includes Max Clean indicator bristles that gradually fade in color to remind you when to swap heads. As bristles thin and color fades, cleaning effectiveness can decline, so replace according to the indicator or every three months with regular use.

• Green-to-yellow indicator bristles signal replacement time
• Typical replacement period: about 3 months with regular brushing
• Replace sooner if bristles fray or after illness

Which toothbrush handles are compatible with these refills?

These FlossAction brush heads are compatible with most Oral-B rechargeable toothbrush handles that use round brush heads. They are not compatible with Oral-B sonic or Oral-B iO series models, which require their own head types.

• Fits Oral-B oscillating/rotating rechargeable handles
• Not compatible with Oral-B sonic or Oral-B iO handles
• Works with common Oral-B models used in households

What do I get in this 5-count pack and how should I store them?

The package contains five genuine Oral-B FlossAction replacement heads, enough for multiple replacement cycles or for sharing among household members (each person should have their own head). Store heads upright in a dry place and keep protected from direct contact with other heads for hygiene.

• Five individual brush heads included in the pack
• Store in a ventilated holder to dry between uses
• Label or assign heads if sharing among family members

Who is this for: The Oral-B FlossAction 5-count replacement heads are ideal for people using compatible Oral-B rechargeable toothbrush handles who want a round-head design with bristles engineered to reach between teeth. They suit households that prefer to keep spare heads on hand, couples or families assigning individual heads, and anyone looking for a replacement option that includes indicator bristles to help time replacements.
