Hello,I hope I can be of service.
can take a up to a couple of weeks to settle down after a root canal.
Typically the only sense remaining in the tooth after any inflammation from treatment has settled is that of touch which comes from the area around the tooth and not the tooth itself. You should not notice any temperature sensitivity. A well fitted temporary crown should not add to the sensitivity.
chewing has been a problem...
it hurts to chew on that side of my mouth and the temporary crown is sitting over my gum. It is my first time getting a root canal
That is the typical type of sensitivity after a root canal. The area at the end of the root becomes sensitive because the nerve has been taken out of the tooth and hence separated from the bone area. It will take a short while for that the heal over. That is assuming the temporary is not high in the occlusion (bite).
okay i guess i dont need to worry too much...How long does the sensitivity take to go away? I will try to chew on one side of my mouth
A couple of weeks should do it. It's best to take it easy on that side for a few days.
