I remember going to the dentist in my 20s, he said that a root was inflamed and needed treatment immediatly, otherwise the root could die and so on and so on. Then he told me how much it would cost, since the insurance doesn't cover that treatment, it was about 1800 euros. I asked him in all seriousness if my insurance would pay if I just would let things happen and get my tooth pulled out afterwards one day, since 1800 Euro was waaay to much for me to pay those days - and still is.
