iO Ultimate Clean Replacement Heads

The pack contains four black brush heads designed for Oral-B iO Series rechargeable handles. The Tuft-In-Tuft bristle pattern combines longer inner tufts for hard-to-reach areas with shorter outer tufts for surface cleaning. They are not compatible with Pro, Smart or Genius handles.

Soft Bristles and Colour-Change Indicator

Each head uses soft nylon bristles set at a 16° angle for plaque removal. Colour-changing bristles fade to signal when a replacement is due, typically around three months. No battery or power source is involved.

The sealed box measures 16.03 cm by 11.53 cm by 4.6 cm and weighs .0955 kg. The small footprint fits easily in a bathroom cabinet or travel bag. Genuine Oral-B heads ensure the handle's cleaning modes perform as intended.

Questions about this item

How do I fit the iO Ultimate Clean head onto my iO handle, and what mistake should I avoid?

Align the head and press straight down until it clicks; do not twist it, as the connection is a friction fit, not a screw thread.

When do the colour-changing bristles tell me to replace the head, and what is the dentist guideline?

The bristles fade halfway after about three months, matching the dentist recommendation to change heads every three months to limit bacterial build-up.

Which compatibility limit appears first if I try to use these on a non-iO Oral-B handle?

They only fit iO Series rechargeable handles; they will not attach to Pro, Smart or Genius handles because the coupling geometry is different.
