Can you catch gingivitis from kissing? Myth or reality

Can you catch gingivitis from kissing? What lies behind the myth

After a night of drinking, a kiss with someone who had inflamed gums sparked alarm on consumer forums. The question keeps coming up: can oral bacteria be transmitted through saliva? The short answer is yes, but not everyone knows it.

One user describes how, during a round of shots, a stranger pushed her tongue all the way down his throat. Days later, upon seeing her red gums, he antiestéticared he had contracted gingivitis. Beyond the grotesque details, the story opens up a real issue: the transmission of periodontal disease.

Gingivitis is a bacterial infection of the gums caused by plaque. Although it is not considered a sensual transmitted disease, the bacteria responsible can pass from one mouth to another through direct contact. Research has found that couples who live together share similar strains of periodontal bacteria. However, the actual risk depends on the recipient's oral hygiene. A healthy immune system usually keeps the invasion under control without the disease developing.

That said, the experience of another sufferer, who has been dealing with an infection for over a month without the dentist being able to identify it, suggests that some strains can be persistent. The patient claims the tartar removal treatment was not enough and that the source appears to be an unclassified bacterium. While science points to known microorganisms such as Porphyromonas gingivalis, there are still hard-to-diagnose cases.

When in doubt, antibacterial mouthwashes can reduce the microbial load, but they do not eliminate the risk if contact is repeated. As with so many things, prevention starts with your own hygiene, not someone else's.
