How do the microfiber, triangular-tip, and square-cluster bristles work together compared to a regular soft toothbrush?

Most soft toothbrushes use uniform round-tipped filaments. This brush combines three distinct bristle designs: fine microfiber filaments that are thinner than standard bristles, allowing them to slip into tight spaces and conform to curved tooth surfaces; triangular tips shaped to penetrate the contact points between teeth where plaque often starts; and square-cut bristle clusters positioned to clean the gum margin and provide a light massaging action. Together they address the three main zones — interdental, gingival margin, and broad surfaces — without requiring heavy pressure. The microfibers do the detailed work, the triangles reach the contact points, and the squares sweep the gum line. Because all filaments are soft, the brush remains gentle on enamel and sensitive tissue while still disrupting biofilm effectively when used with proper technique.
