I had two (out of a planned three) unpleasant root canal treatments on a back tooth. Unfortunately, towards the end of the second session my dentist broke his file, leaving a bit in the root. I could tell he was seriously peed off at this stage, especially when he proceeded to give me three options:
Extraction, go private, or he could refer me to the Leeds teaching hospital where, presumably, students could have a go at it.
Obviously, he felt giving good NHS treatment wasn’t worth the extra effort.
I went for the extraction, but I hate the gap in my teeth, even though it isn’t visible, even when I smile.
I have a new dentist now, obviously!
