This happens all the time.
People, who neglect their teeth, will wait until they have a tooth that is
broken off at the gums to come to my office to get it extracted.
The laugh a little nervous laugh and say...
"well, not much left so it should be pretty easy yo pull out, huh?"
The answer to that is, NO.
Imagine getting a fence post out of the ground.
Not the easiest thing in the world, right?
Now, take a chain saw and cut the fence post off at the ground.
How easy is that going to be now?!
If you want a tooth out, please, please, please, do not wait until
it is so broken down that there is nothing to grab on to.
It is NOT easier.
