Ten Reasons Why Kissing People Is Grosser Than Kissing Your Dog
If we were to tell you kissing another human is as unsanitary as getting a slobbery kiss from a dog, would you believe it? For the 25.2% of Seattleites who own a dog, receiving a peck from your pooch may actually be on par, health wise, with kissing another person. Who to kiss? Your pooch? Or your partner? Decide for yourself after weighing the facts at our exhibit GROSSOLOGY: The (Impolite) Science of the Human Body.
- Bacteria live on your teeth and tongue. In fact, there are between 100 million and 1 billion bacteria on each tooth.
- Even if you keep your mouth clean, about 100 to 200 species of bacteria live in your mouth at any given time and grow consistently throughout the day.
- If bacteria weren’t bad enough, fungus grows in the oral cavity.
- On top of that, viruses that cause diseases such as the flu, periodontal disease or mononucleosis are found in the human mouth.
- White blood cells from another person’s saliva will attack the cells in your mouth.
- You’ll have the leftovers of whatever food was consumed by the person you kiss.
- Everyone’s spit contains a little bit of urine from their glands (gross!)
- Tartar build-up causes bad breath, making kissing unbearable.
- Because the nose drips down the back of the throat, that big smooch might be mixed with mucus. (Bonus gross fact: a person produces about a quart of mucus each day!)
- A dog’s mouth contains enzymes not found in the human mouth that fight infections. But dogs also poke their noses into unsavory territory and lick all kinds of things, so their mouths can contain hundreds of different types of bacteria along with fungi, Salmonella and a few parasites that present a small risk of infections in humans, especially babies, folks with weaker immune systems and people with open sores or acne on their face.
