From what I understand the risk associated with Teflon pans is mostly with manufacturing with them, and the chemicals affecting manufacturing workers and getting in waterways, not cooking and eating from them.

The risk from heating them up is generally considered to be minor, and an uncommon accute risk, rather than something that happens regularly and that affects long term health. Adam ragusea did a very well reseached video on the subject where he spoke to experts about where the risks do and don't lie (actually it looks like he's done two, this is the more recent one)

But do know that buying them facilitates their manufacture, and the impact on workers and the environment is pretty horrible.

The chemicals involved are often called "forever chemicals" because they basically never break down, meaning they'll pretty much just accumulate for as long as we manufacture things with them, which includes A LOT of different products. Rain coats are often made with them, and aren't supposed to shed pfas or pfoas, but evidently do anyway at alarming rates, and our water sources are already fairly contaminated. This video does a really good job of covering that side of the conversation about "forever chemicals"
