Quick answer

Attach the Oral-B Aquafloss nozzle to your Oral-B Water Flosser Advanced handle, choose the stream mode that fits your needs, and aim the tip at a 90-degree angle between teeth while following your gumline.

Why the nozzle matters

The Oral-B Water Flosser Advanced Aquafloss Nozzle turns a standard water flosser handle into a more versatile tool. Because the nozzle is the part that actually directs the stream, picking the right mode and technique changes how well you clean between teeth and massage your gums.

The nozzle works only with the Oral-B Water Flosser Advanced Portable Handle, so check that you have the compatible handle before buying or using it.

How to choose the right stream mode

The Aquafloss nozzle offers two stream styles. Focused mode sends a targeted stream for precise cleaning between teeth, while Rotational mode creates a spinning stream that massages the gums. Decide based on your main goal: use Focused when you want to dislodge food or target a specific spot, and Rotational when your gums feel tender or need stimulation.

You can switch modes during a session. For example, start with Focused to clear debris, then switch to Rotational to finish with a gum massage.

Step-by-step guide

  1. Attach the nozzle securely: Push the Aquafloss nozzle onto the Oral-B Water Flosser Advanced Portable Handle until it clicks into place. A loose fit can cause leaking or reduced pressure. Check that the nozzle is locked before filling the reservoir.
  2. Fill the reservoir with lukewarm water: Use lukewarm water to avoid sensitivity. If you want a refreshing feel, you can use cold water, but avoid hot water as it may irritate gums or damage the unit. Empty leftover water after each use to prevent bacterial buildup.
  3. Select your stream mode: Choose Focused mode for targeted cleaning between teeth or Rotational mode for gum massage. You can switch between modes mid-session if needed. Start with Focused mode if you are new to water flossing to get used to the pressure.
  4. Lean over the sink and aim the nozzle: Lean forward over the sink, place the nozzle tip in your mouth, and aim it at a 90-degree angle to your teeth, just along the gumline. This angle helps the stream clean the gap between teeth without spraying water everywhere. Keep your lips slightly closed to reduce splatter, but do not seal them tightly.
  5. Work through each tooth gap systematically: Move the nozzle along your gumline, pausing briefly between each tooth to let the water flush out debris. Follow a consistent order, such as starting at the back and working toward the front, so you do not miss any spots. Spend at least two minutes total to cover your whole mouth.
  6. Clean and store the nozzle: After use, turn off the unit, detach the nozzle, and rinse it under running water. Store it upright or in a dry place to prevent mold or mineral buildup. Replace the nozzle every 3 to 6 months or sooner if the bristles or tip show wear.
