Quick Answer

Snap the Oral-B iO replacement brush head onto the handle until it clicks, align the bristles with your gum line, and let the smart pressure indicator guide your brushing pressure.

Why Proper Installation Matters

A loose or improperly seated brush head can reduce cleaning effectiveness and cause noise. The iO's precision engineering means a simple click ensures the brush head is locked securely for the 40,000 micro-vibrations per minute to work correctly.

Step-by-Step: Install and Use Your Oral-B iO Brush Head

  1. Step 1: Remove the old brush head: Pull the old brush head straight away from the handle. Do not twist or use excessive force—it should come off easily. Check for any debris inside the handle cavity before inserting the new head.
  2. Step 2: Align and snap on the new head: Line up the brush head's base with the handle's shaft. Push firmly until you hear a single click. The head should not wobble or rotate freely. Snap on until you hear a click—no click means the head is not secure.
  3. Step 3: Wet the bristles and apply toothpaste: Run the brush head under water for a few seconds to soften the bristles. Apply a pea-sized amount of toothpaste onto the center of the brush head. Wetting the bristles helps spread toothpaste evenly and prevents splattering.
  4. Step 4: Start brushing with correct technique: Place the brush head at a 45-degree angle toward the gum line. Turn on the toothbrush and move it gently from tooth to tooth. Let the brush do the work—do not scrub. The smart pressure indicator lights up if you press too hard: reduce force to avoid gum irritation.
  5. Step 5: Clean and store the brush head: After brushing, rinse the brush head thoroughly under running water. Shake off excess water and store it upright in a dry place. Replace the brush head every three months or when the bristles become frayed. Replace the head sooner if the indicator bristles fade to half their original color.
