In my personal experience they do exist.
Teflon coated pans are, that are properly cleaned with a cleaning brush(the wooden ones) and not with a cleaning sponge with a rough surface. Like this :
Those sponges damage the teflon coating.
Also, using wooden spatulas instead of knifes and forks to turn over the egg or meat helps preserve the teflon coating. Teflon coating is very easily mechanically damaged because it will not stick to anything.
But some say you should worry about PFOA begin released. I think that when the pan cleaning properly and not over heating, PFOA's are not a problem.
EDIT:
These wooden cleaning brushes are fine :
I also always put some boiling hot water in the pan with some soap to soak the oil and meat residu after cooking. This makes it easier too clean the pan after about 10 minutes of soaking.
