The press release includes an image of a person brushing and looking at an image of their teeth on a phone. If you are actively brushing with toothpaste, the quality of the image will likely be as good as an unprepped colonoscopy.

It’s unlikely to yield any actionable information, other than scratching the pimple-popping gross-up itch.

On second thought, I am now half-expecting a home colonics device from Dyson. Easy setup… just lay down on your side in your bathtub.

> unprepped colonoscopy

That is a phrase I didn't have on my HN bingo card for the day.

That’s why they developed a special toothpaste with less foaming (see the presentation video on youtube)

Plot twist: you can use the same device for mouth and colon cleaning.
general_reveal•33m ago
Toothbrushes are a crappy device. I’ve seen some stuff lately that’s like a whole mouth brush, like a mouth guard. With a small pipe to the mouth guard feeding water, you can pretty much car wash your mouth every morning in 60 seconds. Sloshing water around in your mouth often creates way more pressure allowing water to go through the gaps in your teeth (cleaning them). But the waterpik sellers will convince you that isn’t true.

That’s the problem with highly skillful people that follow tradition. I’m sure the engineers are brilliant behind this (camera toothbrush designers), but they are still following tradition of this old idea.

Anyways. Sometimes you have to trust that you are well beyond tradition and are free to redefine all rules. Be fearless.

That whole mouth brush is also crazy exspensive, while I'd assume Philips' Sonicare line is well and profitable

Hmm, they didn't go with CamJet..

What a stupid design. The jet stream can't even reach last back teeth.

It wouldn't be a dyson without a shitty design.

The only dyson products I've used that didn't suck were their vacuums. (To be clear, their vacuums are shit and do not suck as well as even a cheap shark.)

I have a Waterpik Fusion 2.0

Sometimes I’ll add mouthwash or hydrogen-peroxide to the tank, it works well. Usually I start with a quick rinse, then a brush with the flosser on, then a finishing brush with the flosser off.

I see this and am unsure if it’s over-engineering a less effective solution. It’s neat, but I can’t say it excites me; am curious to see reviews and comparisons. The form factor does seem a bit odd though, visually it’s mediocre imo.

I had some deep-ish gum pockets and switched to this pattern, and many of them resolved over a year without intervention:

0. tongue scraper 1. brush with normal toothpaste 2 min 2. floss 3. mouthwash 4. rinse 5. brush with a dry toothpaste that you don't rinse

I started to treat it like an important health step, less a chore. Like exercise or cooking healthy food instead of buying shit takeout.

The year is 2031, the Meta LlamaBrush won't start until it's played a 30s unstoppable ad for Doritos spearmint.

I saw this on X and assumed it was well done satire of the current state of the industry.
mikert89•16m ago
Thought I read elsewhere that if these get dirty they are essentially blowing dirty water into your gums, which can cause health problems

tools like this almost need the same level of sanitization you would see at the dentist.

other than that, I am very interested

Don’t get it dirty

Qualified product should use antimicrobial plastic. You still need to disinfect it using mild disinfectant like iodophor.

I don’t even see how you can share direct to TikTok with this? Or have they got their own social network for toothbrushing? Can I use this to talk with someone using the Dyson ActiveDouche?
