1. Wash thoroughly after each use of toothbrush, and shake off the moisture as far as possible. Put the toothbrush head up in the mouthwash cup, or in a ventilated and sunlit place, to make it dry and sterile.
2. If conditions permit, two or three toothbrushes can be purchased at the same time for rotation, so as to prolong the drying time of toothbrushes. This is especially important for people with gingivitis and periodontitis. In addition, rotation can also maintain the elasticity of toothbrush bristles.
3. Old toothbrushes with loose or curly bristles and no elasticity must be replaced in time, otherwise they will be harmful to teeth and gums.
4. Children living in groups should concentrate their toothbrushes once a week for thorough cleaning and disinfection.
5. Toothbrushes should not be used together to prevent infectious diseases.
6. The placement of toothbrushes should not be placed in the bathroom or bathroom, but should be kept at a certain distance from the cleaning supplies.
