According to the bacterial culture of the used toothbrush by two dentists in the United States, the new toothbrush contains many kinds of bacteria, such as Candida albicans and Streptococcus hemolyticus, which can enter various organs through blood vessels and lymphatics and cause many diseases, such as thrush, acute tonsillitis, pharyngitis, rheumatic fever and acute glomerulonephritis. This is a potential threat to health.
In order to remove pathogenic bacteria from toothbrushes, three effective disinfection methods are introduced.
1. Alternate use.
According to scientific research, some pathogenic bacteria can die by themselves after full exposure to air for one week. This requires two toothbrushes to be prepared and used alternately for a week.
2. After brushing each tooth, apply a layer of soap with high bactericidal activity to the toothbrush, wash the soap 24 hours later, and then apply it after use.
3. Immerse in 0.1% fresh and clean or 0.1%-0.5% peracetic acid.
After brushing the teeth, put the toothbrush into the container containing the above disinfectant. The disinfectant should be a little more than the hair of the toothbrush. Wash it when you use it, and replace the disinfectant after one week.
