What Toothbrush Users Truly Need
Gentle on Gums
Rounded filaments clean effectively without irritating or scratching gums.
Effective Plaque Removal
High-density, high-quality filaments reach tight spaces for thorough cleaning.
Durable & Shape-Retaining
Premium PA612, PA610, and PBT filaments are engineered to maintain their stiffness and original form, ensuring reliable cleaning performance over time.
Water & Bacteria Resistant
The low water absorption rate of our bristle materials (PBT in particular) effectively inhibits bacterial growth, keeping the brush head more hygienic.
Problems Caused by Low-Quality Toothbrush Bristles
Gum Irritation & Bleeding
Sharp or stiff bristles can damage gums during brushing.
Inefficient Cleaning
Poor-quality filaments fail to reach tight spaces or remove plaque effectively.
Quick Wear & Deformation
Low-grade filaments bend or fray after short-term use.
Bacteria & Odor Build-Up
High-absorption bristles retain water, promoting bacterial growth and bad odor.
