Root canalled tooth still sensitive/hurts on touch after a week?!

Root canalled tooth still sensitive/hurts on touch after a week?

Okay so, I had an infection in my 2nd molar.

I went the first time and they removed some of the nerves, just to calm the tooth down and to prevent the constant pain I was in. Then I went back a week later and they took the rest out, and then last week they finally finished everything and prepared it for the crown...

It's been a week and a half or so since then, and now I suddenly have pain on the left side of the tooth when I touch it (it doesn't hurt otherwise, and it doesn't really hurt that bad to begin with, but there's definitely some sort of pain on the left side when I touch it, either when biting down or just touching it with a finger.)

Is this normal? I know that they said the tooth will be very sensitive and I should be careful with it (I didn't want the temp crown because the bite was off and it was bothering me so they just said not to eat on that side and i'll be fine..) Should I call and get it checked out anyways? or is it just because the tooth is sensitive?

It's just a little sore, nothing I can't deal with... and it's not constant pain, but rather just a tiny tingling sensation of pain when I touch that side... it might be just because of the gums surrounding the tooth that they worked on to prepare the area for the crown, I can't really tell to be honest.

The appointment for the crown is supposedly on thursday, but it might arrive earlier.

I mentioned the biting thing because they kept trying to fix the temp to match my mouth but did a very bad job (the dentist let some assistant do it, and he tried doing it for over 20 mins and couldn't get it right so I just walked up to the dentist and asked if I could just leave and not eat on that side and he said fine.

It DOES feel like it's the gum surrounding the tooth that hurts and not the tooth itself, and I can't really tell you if it hurts when I bite down because the tooth is really low as is.

I'll show it to him and have him test it or whatever but I think it'll be fine for the most part...

Pain when biting is not a good thing on a root canalled tooth, it could possibly mean the root is fractured. If it were soreness in the gum, usually that tends to gradually get better, and within a week or two should be, under normal circumstances resolved. I wouldn't have a crown put on that tooth until the pain issue is solved. You don't want to add the expense of a crown whent he foundation is shaky at best. See if your dentist can take the tooth MORE out of occlusion and fit you with a temporary to see if the tooth calms down. Fractures are hard to detect, xrays won't show it, especially if it is small, but have your DDS hold on that permanent crown until you know for sure what you have got. (If you couldn't stand the bite of temporary crown, how much worse would a permanent one be)
Good luck! Hope it all works out well for you :o)
