Gyro/accelerometer measurements alone can't tell you how well you cleaned your teeth, only how you moved the toothbrush. A simpler and more effective solution is plaque-staining dye:

- DoofusOfDeath 6y agoThanks so much for the reminder about disclosing tablets! We had them when I was a kid in the 1970's. I've wanted a way to check the quality of my brushing, and my kids' brushing as well. I totally forgot about these.
- corytheboyd 6y agoThis comment is like the one person in the room at <startup company> trying to say an idea is bad who is drowned out by others foaming at the mouth with reasons to build complexity for the sake of it
- burrows 6y agoCan we make some other assumptions, then the gyroscope data is useful?
- corytheboyd 6y agoFor the record I’m not putting down the author, I love a good hack for the sake of hacking :)
- arcticbull 6y agoOr me any time I say anything negative here about cryptocurrency haha
- fakedang 6y agoYou know what would be awesome? A toothbrush that collects gyroscopic data, sells it off to gaming companies that want to study user hand and arm behavior, so that they can optimize their games for it. Added bonus: if the toothbrush company decides to mine crypto currency for the 23hrs and 50 mins you won't be using it each day. /s if it isn't obvious lol

- Fnoord 6y agoDental hygienist use these here. Though n=1 (snapshot), its a useful way to figure out where you are lacking with regards to brushing, as long as you are honest to yourself when making the snapshot.
- Normal_gaussian 6y agoYes. The positional data is a great way to determine that something was missed. If you missed a spot then you definitely didn't do a good job of cleaning your teeth.
- nextos 6y agoThere's also a great complementary trick. If your floss gives a funny odor when examined closely after going through a single interdental gap, you have too many anaerobic bacteria there. Those are the nasty ones that destroy your gums. This is the poorman's version of bacterial cultures and BANA tests, which IMHO were great ideas but never took off. Dyes are good for tooth plaque, which is a different kind of biofilm. You can have good dental hygiene, but bad gum hygiene and vice versa.

- nojokes 6y agoI am wondering how such situation develops as flossing your teeth should in theory avoid such issue, or not?
- httpsterio 6y agoWell, infrequent flossing would do that. I floss once a week and occasionally it leaves a slight smell, I know I should do it more often but that's a habit I've had to learn as a grown up.
