Sensitive teeth can be caused by a variety of reasons, such as enamel wear, gingival margin recession, pulp exposure, etc. Common symptoms include pain or irritation when eating hot and cold foods, and bleeding or discomfort when brushing your teeth.
For sensitive teeth, it is more appropriate to choose a nylon brush filament with a higher softness. This reduces friction and pressure on the enamel and gum margin, avoiding further damage. Nylon brush filament is a common toothbrush material, which has the characteristics of high softness, good wear resistance, and not easy to deform. It effectively cleans the tooth surface and between teeth without causing damage to the tooth enamel.
Most of the toothbrush filaments on the market use nylon filaments and PBT filaments, and the raw materials of toothbrush nylon filaments are generally nylon 610 and nylon 612, which have low water absorption and can maintain good performance in the humid environment of the bathroom.
In addition, nylon 610 and nylon 612 also have excellent wear resistance and bending recovery, especially can be applied to the high wear resistance of electric toothbrushes for toothbrush filament, the monofilament recovery rate is more than 60%, 610 and 612 nylon filaments show good rigidity and anti-lint performance, good resilience, strong toughness, can penetrate deep into the gaps between teeth, effectively clear plaque and food residues, higher cleaning efficiency, and longer service life of the toothbrush.
