Lumina is working to develop and distribute oral probiotics that outcompete typical mouth bacteria and do not excrete cavity-causing lactic acid: https://www.luminaprobiotic.com/
Some people are allegedly already undergoing this treatment: https://twitter.com/Aella_Girl/status/1726388994575929610?t=a1n14mUOcYVxA4PJzEENgg
My question is, is it possible for this GMO bacteria to spread directly between two people? The transmission could be intentional or accidental, but must be direct (doesn't count if it's cultured outside of the mouth before being applied)
I will resolve to YES if I get and confirm a credible and unambiguous report of this happening by the end of 2025, or NO if I do not.

@t3ss To my knowledge transmission is pretty unlikely. The original inventors self-applied and claim there's been no horizontal transmission over 20 years to their partners. It also isn't trivial to get to stick into your mouth at all; i had to apply an extremely high concentration and brush it in for a long time, after rubbing a bunch of dental polish to disrupt the biofilm. Normal saliva exchange would presumably not really disrupt the biofilm, nor be high enough concentration to latch onto the disrupted areas if it did.
