By basically anyone’s standards, I’m kind of a health nut. A large part of my job is knowing about evidence-based health practices, after all. So when I saw this TikTok warning people that cavities are contagious, I was floored. Not only have I been blissfully unaware that tooth decay is infectious, it certainly never occurred to me that I could “catch” a cavity with a simple kiss. Now this viral TikTok has me scared of kissing people.
