Your mouth is undoubtedly the dirtiest part of your body. It has the largest amount of bacteria because it comes into contact with so many different germs each day. In fact, Dutch researchers actually conducted a study about kissing.
They found that a single kiss that lasts for only 10 seconds can result in the transfer of over 80 million germs between two people. Imagine if you were to kiss your partner several times a day. You'd share many more germs than this.
Remco Kort conducted another similar study. In it, he discovered that the more a couple kisses, the more similar they become. This is especially true of intimate kissing - the kind in which full tongue contact occurs and saliva is exchanged. While this happens in over 90% of known human cultures, it's something that only humans do. Obviously, animals understand how this is germ-laden.
How Dirty our Mouths Really Are
The tongue seemingly has the most germs here. This is because germs can easily take up residence here. It's the area in which communicable diseases also start - including flu, the common cold, and other respiratory diseases.
In fact, researchers discovered that over 700 different types of bacteria and over 100 trillion microorganisms live on your tongue. Some of the other diseases that can be transferred through kissing include the herpes virus, hepatitis B, and even warts. Kissing can also transfer bacterial diseases like Meningococcal disease and tooth decay.
