Whenever you see a Youtube video from a restaurant kitchen you can almost be sure to see some pans where the teflon has been scrubbed down to the pure metal. Probably not that healthy...
PTFE is extremely chemically inert. There's possibly some risk from ultra-fine particulates that could be absorbed by the body, but compared to all the other sources of particulate exposure I don't think it's a major problem. I'm more concerned by thermal decomposition, which forms all kinds of mystery chemicals of unknown risk profile. Restaurants love to sear food and I wouldn't be surprised if some of them do it on PTFE cookwear.
its highly unlikely any restaurant uses teflon coated pans. Most use carbon steel or stainless. Teflon just won't hold up in daily use at a restaurant.

restaurants also love high-heat and that's a no-no for teflon
