Periodontitis is a gum infection in which the bacteria that causes the infection moves through the saliva. Kissing and close contact have a part in the spread of the illness, so if you're married to someone who has periodontal disease, your chances of developing gum disease are somewhat raised. Coughing, sneezing, and sharing utensils and food have all been shown to cause saliva contact in family situations in other research. Periodontal disease is more likely to develop in children whose parents have the condition. At the same time, simply exchanging bacteria with family and friends does not guarantee that you will develop periodontal disease. There's also evidence that oral bacteria can only be transmitted beyond a certain age, when hormones allow bacteria to proliferate and spread in your mouth, producing a disease-hosting environment. This normally happens around puberty, so it's fine to discuss with younger children, but it's important to remember that the habits we form as children persist over into adolescence and adulthood.
