Kissing comes with risks. You might fall in love, catch a cold, or be grossed out by bad breath
Cavities are caused by the bacteria that naturally form around your teeth and on your gums. Regular cleanings and good oral hygiene keeps that bacteria in check
The truth is, you can technically catch a cavity from someone else through kissing and even other ways
However, the problem isn’t necessarily the cavity itself but rather the bacteria that may have caused that cavity in the first place
You see, we all have millions of bacteria in our mouths and a few dozen different types. Some of these bacteria are good and can benefit oral health
Others, such as Streptococcus mutans and porphyromonas gingivalis, aren’t so good and are actually flat-out considered bad, cavity-causing bacteria
If you take great care of your oral health and brush and floss regularly, you may not have bad bacteria in your mouth, or at least not much of it
However, when you kiss someone who does have those bad bacteria, they can easily be transferred to your mouth
