Thanks for putting up your question on Just Answer.
To put it simply, if your tooth is still painting 9 days after getting a root canal, there is something wrong. The tooth needs to be re opened and cleaned again.
And of course you are right, there is no question of getting a crown till your symptoms subside completely.
The fact that you have no insurance complicates matters a little. One option is to go back to your dentist, be very assertive and demand that the pain should first be taken care of. If he agrees, then it won't cost you anything extra.
If he says no, it's time to look elsewhere. I can suggest a few cheaper alternatives to you, but right now my phone browser is not allowing me to copy paste those links here. I can do that from my PC when I get home in a few hours from now. Would that be OK?
