HELP PLEASE ... will they remove half a cracked tooth at the ER if it is swollen in the mouth, etc? like to as?

HELP I DO NOT WANT TO WASTE MINE OR THEIR TIME...

i had a root canal about 5-6 years back and they told me i would need a cap or something because of the root canal. i never had that done. well the tooth had almost all filling in the center and no tooth left around it and now the tooth has cracked and it is coming half way loose in the inside part of mouth. causing pain of course and swelling in the gums and roof of mouth. if i go to the ER will they just give me something for the pain and tell me to go to a dentist, which i do not have, or will they do something about pulling the damn tooth out for me?
