Re: what can cause pain after a crown dental procedure
It could be that the crown is too high and needs to be adjusted.
If it was placed on a "live" tooth, without a root canal, the prep for the crown could have caused the nerve to die and you will now need a root canal.
Or if you did have a root canal, you could have an infection and need a retreatment of the root canal.
Lastly, It could be a gum problem...
