10 Diseases You Can Catch By Kissing Someone

Gum disease

Gum disease is also called periodontitis or gingivitis. While it’s not exactly spread through kissing, it can still be caused by bad bacteria. For example, bacterial buildup around the teeth is the number one cause of gingivitis.

The main symptom of this disease is having red, puffy gums that bleed every time you brush your teeth. Even if it’s a non-destructive type of periodontal disease, people might generally refer to this as gum disease.

There are two types of gingivitis: you can either suffer from dental plaque-induced gingivitis, where the gingivitis occurs as the plaque buildup is irritating your gums, or from non-plaque-induced gingivitis, which results from bacterial, viral, and even fungal infections.
