I’m a dentist, and when I saw this, I had to look at the actual research.
Researchers are experimenting with putting a vaccine onto dental floss and delivering it through this tiny area between your tooth and your gums.
And there’s actually a really interesting reason why.
Deep in that space is something called the junctional epithelium, a thin, naturally permeable tissue that could potentially be used to deliver a vaccine and trigger an immune response.
And this is also one reason healthy gums are so important. When your gums are chronically inflamed, that barrier can become more permeable, allowing bacteria and their byproducts from the mouth to enter the bloodstream and potentially contribute to systemic inflammation.
In mice, researchers tested several types of vaccines this way and saw both systemic and mucosal immune responses, including in areas like the nose and lungs.
And that’s really interesting because those mucosal surfaces are where many viruses first enter the body.
But we’re definitely not throwing away the needles yet.
This hasn’t been tested as a vaccine in humans. Researchers have only tested whether people could successfully deliver material to that area using a floss pick, and about 60% reached the targeted gum pocket.
So we’re still very early.
But as a dentist, the idea that the tiny space between your tooth and gum could someday become a route for delivering medicine? That’s pretty incredible.
