Learn how to replace your Slate Blue nHA Floss Heads quickly and correctly. This guide covers the simple steps, common mistakes, and why these heads offer a deeper clean.

Quick Answer

To replace your Slate Blue nHA Floss Head, press the release button on the handle to eject the old head, then snap the new head onto the metal post until it clicks. The whole swap takes about 10 seconds.

Why the Blue nHA Floss Head Is Different

Unlike standard floss heads that only clean between teeth, the Blue nHA Floss Head is infused with nano-hydroxyapatite (nHA). This mineral compound helps support enamel remineralization with each use. The floss itself is a thin woven material that glides easily into tight spaces, and the head also includes silicone gum brushes and a triple-row tongue scraper for a more complete clean.

Because the nHA coating is active, you want to avoid wiping or rinsing the floss head with alcohol-based mouthwash before use. Just rinse with water and let the floss do its work.

How Often to Replace

Each Blue nHA Floss Head lasts about one week with daily use. If you floss twice a day, you may get closer to five or six days before the woven floss starts to fray. A worn head won't clean as effectively and may not deliver the same amount of nHA to your enamel.

Keep a pack of replacement heads handy so you never have to stretch a head past its useful life.

Step-by-Step Replacement Guide

Step 1: Remove the old floss head: Hold the Slate flosser handle with one hand. Press the release button located on the side of the handle near the top. The old floss head will pop off the metal post. Dispose of it. Common mistake: pulling the head straight off without pressing the release button can damage the post. Always use the button.
Step 2: Inspect the metal post: Look at the metal post on the handle. It should be clean and dry. If you see residue or moisture, wipe it gently with a dry cloth. A clean post ensures a secure fit for the new head. Checkpoint: A bent or cracked post means the flosser needs service. Do not force a head onto a damaged post.
Step 3: Align the new Blue nHA Floss Head: Take a fresh Blue nHA Floss Head and line up the opening on the bottom of the head with the metal post on the handle. The head should sit straight—not tilted. Common mistake: forcing the head on at an angle can break the internal clip. If it doesn't slide on easily, realign and try again.
Step 4: Snap the head into place: Push the floss head straight down onto the post until you hear a firm click. Give it a gentle tug to confirm it is locked. The head should not wobble or slide off. Checkpoint: If the head feels loose or clicks again when you floss, remove it and repeat the snap. A loose head won't clean effectively.
Step 5: Rinse and start flossing: Run the new floss head under cool water for a few seconds to remove any dust from storage. You're ready to floss. The nHA coating works best when the floss is slightly damp. Common mistake: using mouthwash or toothpaste on the head before flossing can wash away the nHA. Stick to plain water.
