The Oral-B CrossAction is designed for professional-grade plaque disruption using proprietary 16-degree angled bristles. This geometry allows for superior interproximal reach compared to flat-trim designs. The mechanical action relies on oscillating-rotating movements that generate fluid dynamics to maintain the gumline without the need for aggressive manual scrubbing.
The filaments are composed of high-quality Polyamide, which is end-rounded to maintain the enamel surface. The indicator technology utilizes a fading dye to signal when the filaments have reached the end of their mechanical life, typically every 90 days. Using the head beyond this point may result in using fatigued, abrasive bristles.
- Technical Advantages: Superior angle for deep crevice maintenance and a reliable mechanical fit that prevents motor strain.
- Usage Profile: The medium-to-firm bristle stiffness requires controlled pressure to ensure sensitive skin maintenance.
To protect the surface from mechanical friction, pair this head with a low-abrasivity toothpaste to condition surfaces during the cleaning cycle.
