Great post. I've had a very similar toothbrush which actually moves to clean the teeth. Maybe this one is better, add I haven't ended up using the one I have regularly
Y-Brush is not “sonic-only.” It uses a mouthpiece full of nylon bristles; the handle provides sonic vibration that moves the bristles to scrub many surfaces at once.
If your similar device vibrates bristles, it’s basically the same technology class; differences are mainly fit, bristle design/material (nylon vs silicone), and how well the bristles reach gumline/interproximal areas.
Effectiveness: studies on mouthpiece brushes are mixed; a 2024 trial found Y-Brush removed more plaque than no brushing but less than manual brushing, and a 2020 trial on a silicone U-shaped brush found it not effective.
Practical implication: many users still need targeted normal brushing + interdental cleaning for gumline/between-teeth.
Y-brush themselves. Just realized! It's an older model from 5 years ago.
Should be 10 seconds top, 10 seconds bottom
I didn't use enough to have an opinion. As I was too irritated with the buzzing of it, I was unwell at the time, and buzzing have me headaches.
But I've seen a seemingly convincing review on YouTube that it works well.
Since then, they added more options. And now the sonic, whicj seems to use the same idea but with sonic cleaning rather than the common way of fast moving the little brushes to clean.

All the best and good luck. Thank you for your work.
Thanks! I'm sorry I didn't have time to try your device last month. I go to lots of biohacking events though, so Let me know if you're attending other events and I'll look forward to checking you out -- I genuinely think the world needs more products like yours.
I generally don't pay attention to FDA registration, which is basically just paperwork and a fee filing. If you've done 510(k) registration, please let me know because of course that's a much, much bigger deal.
There is an older practitioner here in the St. Louis area who has been using acupuncture meridian assessment for a long time. I have one of his books, and based on the case reports he presents, it appears it may be a viable technology.
have you tried it yourself? One problem with acupuncture is that it's highly practitioner-dependent, so almost impossible evaluate with standard scientific experiements.
Obviously, this appears to be a highly sketchy technology, conjuring up thoughts of Scientology methods, but reading through his book, which took me a rather long time (I am a very slow reader), he strikes me as intelligent, thoughtful, and wise. He seems truly driven to help his patients, and the numerous case reports he presents are very persuasive.
What should one keep in mind reading his book?
1) There's not much doubt his methods had to fail on some patients - those are not reported (selection bias).
2) The book was written in part to promote his own practice and draw in new patients. He is a functional medicine practitioner (addressing the root cause of diseases), not an allopathic practitioner (treating symptoms of diseases). The latter is what most mainstream physicians are. Of the few functional medicine practitioners I've looked into online, most aren't willing to file insurance claims - the patient would need to do that, and it's probably going to be out-of-network. As a rather frugal (cheap) individual, I'm probably not going to do it unless I win a lottery jackpot or something.

which brand? How long does it take? I know of several attempts to make "smart" toothbrushes, though I've not tried them myself. (You might remember more of what we wrote about oral hygiene in PSWeek240229: https://www.personalscience.com/p/personal-science-week-240229-dentistry
Gemini thinking is much more positive than gpt here.
Gemini is more informed, so I trust Gemini here

I’m really tempted to snag that sleep device! Thx!!

He isn't a traditional acupuncturist but uses an instrument like this, perhaps an older model, but made by the same company:

To be clear, his instrument may be made by a different company, and it is certainly older, but it does use the Voll method.
