Silicates like glass and asbestos are hard and cause physical damage, but PTFE is a soft polymer.

  Small chemically inert substances can gunk up your cells and tissues even if they are soft.

    The don't make into your cells and tissues, because they're not digestible. Anything bigger than a "small molecule" doesn't make it through the membranes into your bloodstream. Even individual proteins are too big, let alone a chunk of your frying pan big enough to see.

      When talking about a small polymer, I was mainly commenting on microscopic flakes and lakes laced with "chemically inert" molecules that have devastating physiological effects. Either way, what you claim is simply not true by any reasoning [1], though I do agree eating teflon flakes in moderate amounts should not pose much concern.
