Oral-B iO Gentle Cleaning Interchangeable Brush Heads for electric toothbrushes.

The Gentle Cleaning brush heads by Oral-B iO, both firm and sensitive, are specially designed for sensitive gums.

• High bristle density: Gentle Cleaning brush heads feature up to 4,000 soft bristles for gentle and excellent cleaning.
• Color-changing bristles: Oral-B brush heads have bristles that change color, indicating when they need to be replaced for optimal cleaning.
• Replace every 3 months: A worn brush head makes cleaning difficult and leaves bacterial plaque. For better cleaning, replace the brush head when the bristles have faded.

Compatible exclusively with Oral-B iO electric toothbrushes, they offer exceptional cleaning power.
