Teflon Aka Polytetrafluoroethylene cookware represents a health hazard. The stuff contains a great deal of Florine and breaks down at 300C, but that’s not purely binary instead it becomes increasingly unstable as your approach the temperature. Further no manufacturing process is perfect, I wouldn’t therefore assume eating significant quantities would be safe.
That said, it’s generally used as a coating rather than a structural element so there’s less of it in the environment.
PS: Toothpaste which you should mostly spit out generally contains less than 0.5% fluoride compounds such as sodium fluoride NaF or tin fluoride SnF2, the F in both being Florine.
