Medical statistics show that for every kiss on the lips, there are more than 270 different kinds of bacteria transmitted to each other through the kisser’s mouth. Fortunately, about 95% of the bacteria are not harmful to health, but individuals who lack resistance to 5% of the bacteria can easily contract diseases. Especially in the case of some diseases in the oral cavity, bacteria are more likely to spread and get infected themselves! With a healthy mouth and a fresh mouth, you can enjoy the sweetness of a kiss. But oral experts suggest that people with the following eight oral problems are prone to disease transmission through kissing. Let’s see if you and he are in the following blacklist: 1. People with bleeding gums. Your gums bleeding, then you may spread oral and blood system diseases, and gum bleeding that means the gums or periodontal state of the mucosal barrier is broken, but also easy to infect each other with oral bacteria and infectious diseases. You should know that the skin and mucous membrane barrier is the first barrier that protects the human body, and armor to prevent external pollution, infection, etc.! AIDS is the most intuitive example. If your oral clean mucous membrane is intact and unbroken, and so is the other party, then the actual kissing with AIDS patients is also relatively safe. 2. People with mouth ulcers. These people have the same kind of problems as the above, and some severe ulcers can be confused with tumors. 3. People with swollen and painful gums. The gums are swollen and painful, which means that there is inflammation, and there are more pathogenic bacteria in the mouth itself, thus increasing the chances of mutual infection. 4. People with uneven teeth, crooked teeth, and bulging teeth. This kind of people have uneven teeth, easy to accumulate bacteria and calculus, the number of oral bacteria is relatively large. Of course, there are teeth are not aligned but their own cleanliness is very good, very clean, then pay attention to kissing not to touch the mouth can be! 5, people with gum recession, gums are grayish in color. Gum recession itself is a manifestation of gum or periodontal disease. Obscure gums, either too much calculus, inflammation is heavy, or there is a blood system disease or other systemic diseases, but also need to pay attention to. 6, people with bad breath. Bad breath is actually a manifestation of oral diseases, such as gingivitis, periodontal disease. The actual cause of bad breath is the acidic and chemical substances such as indomethacin, and sulfide and other odors caused by the proliferation of bacteria. 7. People with tooth decay. The cavity is also the hiding place of a large number of bacteria. 8. People with gingivitis and periodontal disease. In fact, most of the aforementioned bad breath, bleeding gums, swollen gums, etc. are the manifestations of these two oral diseases, and here specifically to emphasize its commonness and importance. Gingivitis, periodontal disease, oral mucosal barrier is basically incomplete, that is, the loss of their own first protective barrier, not only will spread disease to each other, themselves will also be easily infected. These eight types of people, there are a large number of germs in the mouth, kissing will “exchange” these germs. If one party carries an infectious virus and the other party catches a bleeding gum or mouth ulcer, it is more dangerous, these infectious germs through the bleeding gum mouth, ulcer wounds into the bloodstream, it is easy to infect each other. If you or your family, have these 8 oral problems, should be early medical treatment, do not drag the small disease into a big problem. For children and adolescents, parents should cultivate the good habit of caring for oral health from childhood, and go to professional dental institutions for regular checkups during the period of tooth replacement, so that he can have a lifetime of healthy and good teeth.
