One of the rare cases where this is a serious option: just don't buy it. People say that for phones that spy on you, but that's ridiculous because that is quite hard for some people. This is not. Use a regular toothbrush. Duck tape a vibrator motor to the handle if you really feel like that helps. You don't need the ai, and it is unlikely that you will only ever be able to buy ai toothbrushes.
Aren't you on a device with materials mined by slave labour that you charge every single day just to look at cat pictures and write comments into a void
I just have an electric toothbrush that stays on for 2 mins and pulses every 30 sec to let me know to switch to a different "quarter" of my teeth. That's literally all the smarter it needs to be. Why the fuck is AI being added.
IIRC, the 2 minutes is the bare-minimum, and intended for someone with perfect teeth and technique. Now most people (ones who aren't perfect) use the toothbrush, their common reaction to the timer completing is they are done brushing. They don't realize that they were likely rushing to keep up with the timer and ignoring different plaque hot spots.
I personally have a couple crowns that my previous dentist screwed up on and mis-sized the base, leaving a ledge where food and plaque get stuck in. If I don't spend extra time around them, tatar will form like a madman. (Same issue with my lingual bar before I had it removed)
I'm alright with a timer to help keep rhythm and let you know when you hit the minimum, but don't make it integral to using the damn brush and turn it off when it hits zero.
this 'AI' all the things stuff really reminds me of the 'smart' all the things trend from a few years back... sooner or later people will realize exactly what should and should not be connected like this... like 'smart/ai' rice cookers and washing machines... and toothbrushes... like WHY??
