The bristles of the Oral-B iO Ultimate Clean Black (4 units) were designed to remove plaque that resides deep between your teeth. The bristles are positioned at a 16-degree angle and adapt to your teeth. This way, they won't miss a spot and they clean all your teeth thoroughly. If you brush your teeth for 2 minutes 2 times per day, you need to replace the brush attachments after 3 months. With this, you'll have enough for 1 year.
Note: these brush attachments are designed exclusively for the Oral-B iO product series.
Suitable for:
All Oral-B iO models
