Microrobots can brush and floss teeth in a proof-of-concept study
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.
