Excuse me, how about a silicone toothbrush?
Features of traditional toothbrushes:
1, the traditional toothbrush generally uses nylon brush wires, which is easy to damage the gums, causing bleeding and atrophy of the gums, which is easy to damage the quality of the gums, and even lead to wedge-shaped tooth defects in severe cases.
2. Nylon is hydrophilic and easy to store water in the brush head. Wet toothbrush head is very conducive to the propagation of germs, toothpaste is easy to remain on the brush plate, dirt is easy to remain in the brush capillary holes, and food residues brushed from the mouth are easy to mix between bristles.
3. Nylon bristles are easy to curl, not resistant to high temperature, and cannot be sterilized at high temperature. Therefore, their service life is short, and they need to change their toothbrushes frequently, resulting in a lot of domestic garbage, which is not conducive to environmental protection.
