The teflon coupler deforms at the end where it meets the hotend. you can check it by removing it and seeing if the end is squished in or has a lip in the inside. This happened to mine over a month ago and i just re-drilled the hole with the correct size drill bit and it has been working fine ever since.

could be, but the best indication would be if you would post the actual inside of the Teflon Coupler.
it is supposed to be a straight shaft, if there are indentations, yes, it will need to be replaced.
