In Chinese families, it is believed that most of them share the same toothpaste, which is convenient and saves a lot of space. In fact, although it is a family, it is best not to share toothpaste. Dentists suggest that toothpaste and mouthwash cups are best for personal use, choose small tube toothpaste, and avoid toothpaste with longer use, the greater the chance of contact with bacteria.
There are so many bacteria in the human mouth that even brushing your teeth every day will not be able to remove them. If a family shares toothpaste, if one of them suffers from gingivitis, periodontitis and other diseases, the toothpaste is likely to become a "transit station" for bacterial infection, and the infectious bacteria will first stick to the shared toothpaste through a family's toothbrush , and then infect other family members through this shared toothpaste.
In addition, when someone in the family catches a cold, if you share a toothbrush, some viruses and bacteria may remain in the toothbrush bristles, which may easily cause the whole family to catch a cold.
Therefore, for toothpaste, it is recommended that individuals use personal ones, so that the possibility of bacterial infection will be greatly reduced.
Of course, if you do need to share toothpaste, it is recommended not to touch the toothpaste with the toothbrush when squeezing the toothpaste, because it is easy for the bacteria on the toothbrush to stick to the toothpaste. After squeezing the toothpaste, Ke gently lifted the toothpaste tube up to let the toothpaste break naturally.
It is worth emphasizing that due to the different oral conditions of each person, such as some people with sensitive teeth, it is necessary to analyze specific problems and choose toothpaste with special formula.
At present, toothpaste can be roughly divided into three categories: ordinary toothpaste, drug toothpaste and fluoride toothpaste. Everyone should choose according to their own oral characteristics and needs, and use different toothpastes in rotation, so that they can exert various effects of different toothpastes, so as to maintain oral health in many aspects.
Otherwise, the long-term use of the same type of toothpaste will also make some harmful oral bacteria develop drug resistance and drug resistance, so that the toothpaste loses the effect of sterilizing and protecting teeth. Therefore, in order to ensure oral health and hygiene, the type of toothpaste can be changed frequently, and the replacement time is preferably one month.
