How to use toothbrush correctly

(1) Wash thoroughly after each use of the toothbrush, and shake away the moisture as much as possible, put the toothbrush head up in the mouthwash cup, or place it in a ventilated and sunny place to dry and sterilize it.
(2) If conditions permit, you can purchase 2 or 3 toothbrushes for rotation at the same time, which will prolong the drying time of toothbrush. This is particularly important for people with gingivitis and periodontitis. In addition, rotation can also keep the elasticity of the brush hair.
(3) The old toothbrush with loose or curled bristles and elastic loss must be replaced in time, otherwise it is not good for teeth and gums.
(4) Children living in groups should concentrate their toothbrush on a weekly basis for thorough cleaning and disinfection.
(5) Toothbrushes cannot be used in case of mutual infection.
