Introduction to the bristles of the toothbrush

The common bristle materials of toothbrushes are nothing more than nylon, polypropylene (pp), polybutyl ester (PBT), and natural bristles. Nylon wire: smooth and elastic, wear-resistant and non-absorbent, and the fiber is soft and elastic, can clean the gap between the teeth, and has a good massage effect; polypropylene: a cheap toothbrush commonly found in hotels, the material is rough, the toughness is poor, and it cannot be used for a long time ; Polybutylester: It has a scientific double-layered bristle structure, soft texture, low abrasion, no deformation, can effectively clean the surface and gap of the teeth, does not damage the gums and enamel, and has a significant effect on removing bad breath and preventing the growth of bacteria (can be Long-term use, slightly more expensive.) Natural bristles: The ability to absorb water and toothpaste is very good, brushing with this material can avoid the waste of toothpaste, and the cleaning effect is also strong. However, the strong water absorption also makes it easy to breed bacteria in a humid environment.
