With the Oral-B Pro Cross Action Black (10 Units), you get brush attachments that allow you to brush thoroughly for 2.5 years. The brush has 2200 bristles that are placed at a 16-degree angle. That way, you can easily remove dental plaque and ensure healthy gums. Every bristle has an x-shape. This allows you to brush the hard-to-reach spots between your teeth as well. The green bristles turn yellow after some time. That way, you know exactly when the brush needs to be replaced.
Suitable for:
The Oral-B Pro, Vitality, Genius, and Smart models.
