I crowned my teeth, root canalled soon after.l have slight pain when grinding. no abscess. is it normal?

Pain source: Pain can come from many sources even after your root canal. The tooth may be a fraction too high in your bite subsequently bruising your tooth socket, the tooth may have had a fracture to start, food may be getting caught around the tooth, some residual bacteria may be caught down deep around the root, etc. A visit with your dentist may lead to some answers or a night guard. Best to you.

Not really: After a root canal procedure and a crown, your tooth may feel different when you chew, but it should not hurt. If it does, there may be a chance that your tooth has a crack in it, or that the bite (what we dentists call 'occlusion') may be a little off. Make sure you have your dentist check the bite when you grind side to side so there are no high spots. Still have pain? Talk to an endodontist.

Can be: The ligament which wraps around the entire tooth root may still be healing. This can be normal and last for up to 6 months. However, you should see your endodontist and/or dentist to check on the bite - it may need to be adjusted. You also may benefit from a nightguard.

Could be normal: Sometimes you can have slight pain after a crown or root canal treatment. Usually the pain will eventually resolve. However, have your dentist periodically check the tooth if you are having pain.

Can be: Root canal its a very successful procedure(over 95%). Sometimes it can take awhile to calm down completely. The important question is if it is getting less sensitive(improving). If not then more therapy might be indicated down the road.
