The simplest deepfake detector I've found is checking the teeth

I was watching a viral video of a politician giving a speech the other day, and something felt off. The face looked right, the voice sounded close, but their teeth kept blurring or shifting between frames. I read up on it, and apparently most deepfakes struggle with consistent teeth rendering because they're complex small shapes with lots of contrast. Now when I see a suspicious clip, I zoom in on the mouth area and watch if the teeth stay stable. Caught three obvious fakes this month alone, all shared by friends on Facebook. Has anyone else noticed this tells after trying other methods?

My coworker Deb spotted a deepfake president video when his teeth flickered gray.

Hmm I'm not totally sure about that. Teeth flickering gray could just be a video compression glitch or a bad frame from the live stream. Deepfakes are getting so good now that simple visual artifacts like that are usually just normal encoding errors.

Dang that's rough. I had a friend who was dead sure they caught a deepfake of a local news anchor when her glasses reflection didn't match the window behind her. Turns out it was just a weird shadow from a studio light. It's scary how easy it is to jump to conclusions when everything online already feels so fake. I dont blame Deb for being suspicious honestly, the tech is wild these days.
