Crown on upper tooth

[hoorahmom]

I just got back from the dentist. I had a temporary crown on my upper right tooth that caused me pain a certain way I'd brush.  It would ache for a few minutes afterward and then go away. Was a little sensitive when I'd bite down too hard but other than that it didn't bother me. I just had my permanent crown put on which was very painful.  I told the dentist about the pain when I brushed and he did some poking around, asking me whether this or that hurt which in one place it did.  He then put the crown on and got the bite right.  He told me I had a little receding gum that was probably causing the pain and sensitivity. He gave me a prescription for a fluoride treatment and told me how to use it on my gums and that should take care of it. What does the flouride do? My tooth is achy a little, is that normal after a crown?  The reason I'm asking is a few months back I had a crown put on and experienced severe pain like I've never felt before in my life and I had to have a root canal.  Now I am worried about a repeat performance.  He told me not to worry about that because the pain I was having didn't sound like it could be a root problem since it didn't bother me all the time, only when I brushed.  And why the heck does it hurt so bad to have a crown put on?  The last one hurt and this one about sent me out of the chair. Thanks in advance for any commments.

you should not be having these problems. If you have sensitivity when brushing that you did not have before, it means that what the dentist did is causing the problem. logical, huh? either the gum tissue was traumatized during the preparation (drilling) of the tooth, causing it to recede and expose the sensitive dentin of the root, OR, the dentist did nt get a full, accurate impression, and a section of prepared (drilled upon) tooth is exposed becasue the margin is too short in this area because this area was not recorded well in the impression. It may also be that the laboratory overtrimmed the die (model) of the involved tooth before making the crown. I'd get opinion from another dentist.
