Can kissing lead to cavities?

Monday - 10.25.2021

What you didn't know about the bacteria in your mouth

Our mouths are home to many species of microscopic organisms. Most of them are harmless, some are even beneficial, but others can cause tooth decay and gum disease. The worst offenders are streptococcus mutans and porphyromonas gingivalis, also known as: bad bacteria. 

This bad bacteria eats the leftover sugars and starches that stick to our teeth after we eat, and then it excretes enamel-eroding acid. This bacteria is also linked to advanced gum disease, or periodontitis.

Managing the bad bacteria

As bacteria reproduce quickly, a good oral hygiene routine is key for keeping the harmful bacteria populations under control. In a healthy, clean mouth, there might be anywhere from a thousand to a hundred thousand bacteria on each tooth, but a mouth that doesn’t get cleaned often can have as many as a hundred million to a billion bacteria per tooth. So don’t skip your twice-daily brushing and daily flossing!

What does this have to do with kissing

On average, an individual will have anywhere from 34 and 72 different types of oral bacteria. Once we get a strain of bacteria in our mouths, it probably isn’t going away. The trouble with this is each person has different bacteria, so kissing or even sharing drinks with someone could introduce new strains of bacteria to our mouths.
