Can Kissing Lead to Cavities?

Wednesday - 02.13.2019

WE HOPE ALL OF our patients are excited for Valentine’s Day! We also hope the topic we’re about to discuss won’t spoil the romantic mood, but we want to share with you what kissing does to oral bacteria.

The Bacteria In Our Mouths

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

Streptococcus mutans eats the leftover sugars and starches that stick to our teeth after we eat, and then it excretes enamel-eroding acid. Porphyromonas gingivalis is strongly linked to advanced gum disease, or periodontitis.

Managing Our Oral 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 surface, 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!

You May be Wondering What This Has 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.







This is more dangerous for children than adults. Young children don’t have the variety of oral bacteria as do adults and because of that their immune systems aren’t used to dealing with them. Too many kisses from Mom and Dad can leave your child more vulnerable to developing cavities.

The best way to avoid sharing your oral bacteria with your child is to keep those kisses limited to the cheek, don’t share your eating utensils with them and make sure they always have their own drink instead of sharing yours with them.


Catch Feelings, Not Cavities

As long as you’re taking good care of your oral health and hygiene, you don’t need to worry about spreading dangerous, cavity-causing germs with your kisses. However, avoid doing things that could spread oral bacteria to small children. If you follow these tips and keep up with your regular dental appointments, you’ll be free to enjoy the feelings of Valentine’s Day!
