The Oral-B CrossAction hardware utilizes a 16-degree angled bristle architecture to facilitate professional-grade plaque disruption. From a material science perspective, the filaments are end-rounded to maintain the condition of the enamel and soft tissues. The "CrissCross" geometry is specifically designed for deep penetration along the gingival margin.
Indicator bristles serve as a titration gauge, using food-grade dye that fades with mechanical wear and exposure to enzymes. This data-driven system signals the optimal time for replacement, as bristle stiffness degrades over a 90-day period. Consistent replacement ensures that the mechanical cleaning power remains at its peak efficiency.
- Data-Backed Benefits: Superior interproximal reach and reliable usage-tracking technology.
- User Profile: High bristle density provides a firm cleaning sensation; users should follow pressure sensor cues to maintain surface health.
To maximize the disruption of surface biofilms, pair these mechanical filaments with a mineral-based paste to condition the enamel post-cleaning.
