Dentist mother makes claim on Tik Tok: Never kiss your child on the mouth

Whilst Joyce has 70,000 followers on the platform, one video on the topic has amassed 2.4m views.

She has multiple videos on the topic, answering questions she has received since posting the original clip.

Joyce explains, “I had a long history of having tons of cavities, and I know that bacteria can transfer […] so I want to give him the best chance of not inheriting my bacteria – my cavity causing bacteria.”

In a follow up video, she explains that in dental school, her class did an experiment where they took saliva from their mouths and grew it on a petri dish. She explains that most of her friends, that had never had cavities, had fairly minimal growth in the petri dishes, however she describes hers as “an explosion of bacteria”.
