gag-proof, no, but by far the best teethers yet
I have the typical teething rings in many different versions.  When my youngest had two teeth break through by 5 months and couldn't keep things out of her mouth, I figured these were worth the try.  As many have stated, I have seen her gag a few times on them.  Within a couple of months, she stopped sticking them so far in her mouth (eliminating the gagging) but continues to gnaw away at these for relief.  Really glad I found these to help her get through all the teething.
