Has anyone else seen single-fanged snakes in the wild lately? This is seriously creeping me out

Okay, this might sound absolutely insane, but I've been seeing/hearing about something really bizarre, and I need to know if anyone else out there has experienced this or knows what the heck is going on.

For context, I'm a casual reptile enthusiast, live near some wilderness, and spend a decent amount of time outdoors. Lately, I've had two separate encounters (one personal, one a friend's story, verified with a photo) with snakes that, upon closer inspection, appeared to have only one functional fang.

I'm talking about venomous snakes – specifically, a small pit viper I almost stepped on, and my friend's account of a cobra. In both cases, the dominant, striking fang was present, sharp, and doing its job... but the other side? Either missing, or just a tiny, undeveloped nubble. Not a recent break, mind you, but almost as if it never fully formed.

Now, I know snakes lose and regrow fangs. That's common knowledge. But this felt different. The consistency across two unrelated observations within a few weeks is what's making my skin crawl. It's almost... deliberate. Like some kind of genetic anomaly or environmental factor is causing this in certain populations.

Is this some weird new mutation? A response to something in the environment? Or am I just seeing patterns where there are none because I've been spending too much time on weird corners of the internet?
