But you're logging actual data with those? Or do they make tooth brushes which monitor your mouth's biome or something like that these days?

Not biome, but it is pretty trivial to track:

- Brushing pressure

- How long you brush

- When you brush

- Where you brush (tracking orientation and motion)

With that, you might see some trend of "you brush your left-back-bottom teeth a little harder than the rest, and you're not quite getting your front middle teeth very well".

Now, if that data is actually useful logged and analyzed is another question.

I've got a toothbrush that theoretically has bluetooth connectivity support. I've never used it. But I do like there's a colorful ring that lights up to show the brushing pressure and I do like the 30 second timer feature to help ensure I brush each area of my mouth about the same amount of time. Neither require bluetooth and an app though.

I'd buy a toothbrush that did that, even if it had "AI" in it's name.

But no, I think it just logs the brush duration and for the more expensive models the "coverage", or something like that.

Yes they make a 3d map of your mouth. It’s nonsensical but here we are

Product owners love that shit. No thoughts or analysis required. "That's so cool...I LOVE IT!" I hear that phrase used on so many boring, bad ideas.

"People want to log and track their health data"?
