I find it strange that there is so little innovation in the field of everyday tooth care. Particularly the inefficiency of brushing one tooth at a time. I like the idea of https://blizzbrush.com/, has anyone tried it? It's a bit suspicious that the single-pack is "sold out", but the 5 and 10-packs are not.

Based on the video, I wouldn't implicitly trust the brush to have enough precision to hit the small chunks of food at the gumline.

Not buying it. That would only work if it were firmer because as it is now I'm extremely doubtful your teeth will magically fall into those grooves when the sponge has so little structure. On top of that it seems hard to clean, A toothbrush is open and has short bristles and often after rinsing it I'll look and still find debris where I need to clean again and deliberately get pieces out.

Totally agree there's too little innovation in this field.

I hadn't heard of the Buzz Brush and it's fascinating to me, although it does look half-baked and too indie at the moment for me to trust it with my dental health.

Also it's too expensive to try as a throwaway test.

Any other cool innovative products that replace standard brushing?

If you are in the US, like me, you might not be aware of Novamin toothpastes. They are available in other countries. It is my understanding that it can enclose dentin tubules exposed by enamel loss.

This article provides some background:

This sponge you put in your mouth made me think for the first time about how much bacteria is potentially on a normal toothbrush.

I'm betting this product is even less hygienic since it's a sponge instead of only bristles.
