This Dentist And Mom Went Viral For Sharing Why She Doesn't Kiss Her Child On The Lips, And Spoiler Alert: It Has To Do With Cavities
Dr. Joyce Kahng, DDS, is a 35-year-old cosmetic and restorative dentist from Costa Mesa, California who owns Orange and Magnolia Dental Studio. She's also a mom, and she recently went viral on TikTok for her series explaining why she doesn't — under any circumstances — kiss her child on the lips:

In her most viral video — which currently has over 2.4 million views — Dr. Kahng explains that when she was in dental school, they did an experiment where they swabbed their mouths and grew their saliva in a petri dish. She found that she carried a larger amount of cavity-causing bacteria than her peers, which she could then pass on to her baby and also give him a lifetime of cavities. Hence, she made the decision that there would be no lip-kissing.
BuzzFeed reached out to Dr. Kahng for more details, and she confirmed that kissing on the lips — as well as other things, like sharing utensils — can indeed transfer cavity-causing bacteria, especially in young children.
"Bacteria can transfer through salivary exchange and this is more common for children, less common for adults," Dr. Kahng explained. "Children are not actually born with the bacteria that causes cavities. These bacteria are transferred to them at an early age, usually from their caregiver through activities like kissing and sharing utensils. After the age of 4 years old, a child’s oral microbiome has matured and is unique to them, making them more resistant during times of salivary exchange."
Dr. Kahng also confirmed that no matter how much we brush and floss, we still might end up with more cavities than the person next to us. "Some people are more predisposed to cavities than others regardless of their level of oral hygiene, and that's because we're not all the same! There are a number of factors besides oral hygiene that make people susceptible to this disease, such as bacteria and genetics."

She continued, "This is not a disease of neglect, but rather susceptibility. If you're a patient who's susceptible, it only takes a low level of biofilm to express the disease. For a patient like this, preventing disease is an uphill battle."
Dr. Kahng told BuzzFeed that she decided to create her series in order to share information and also to share her "mom struggles" when it came to keeping her baby's mouth cavity-free: "Despite my best intentions, I found it was much more difficult than anticipated to keep kisses from my little one, and also be mindful about pre-tasting his food and using his utensils. Sometimes it’s not easy to apply the understanding of science to real life (whether you're a doctor or not). I then realized a lot of people don’t know this science at all — I myself only learned it in dental school."
