Ordinary look, extraordinary performance
New high-density, anti-corrosion, metal-free brush head
Although it looks unremarkable, this small brush head is completely different from ordinary brush heads. Its brush head uses anti-corrosion, metal-free high-density bristle technology. The bottoms of the bristles are joined together using heat, then firmly affixed to the upper portion of the brush head. Unlike ordinary brush heads, there is no danger of metal corrosion or dirt getting trapped between the grooves of metal plating, making this brush healthier and more environmentally friendly. It uses high-quality soft bristles created by the American company DuPont, and its high-density bristle technology allows for bristles that are 40% denser.* Each filament undergoes a polishing process to create bristles that are smooth and round. This ensures that they don't irritate gums or scratch the surface of the teeth.
* Compared to other brush heads with the same surface area, anti-corrosion, metal-free bristles have a density that is approximately 40% higher than metal bristles.
