Question:

Sensitivity under crowns can happen for a variety of reasons: if air gets in, hot or cold foods, etc.
Your dentist may be able to remove the crown, and put a desensitizing agent there.
Infection.
Bad repair job. See your dentist!
I like your piece.
Are you sure its a crown? To have a crown you would need to have a Root Canal on that tooth. Unless it is resent, I doubt that this tooth is your problem. Since there is no root there is no sense of feeling. More then likely it is an adjacent tooth that is giving you the problem. Loose or crack or aged filling might be your problem.
See a Dentist and have it checked. In the mean time gargle with a good mouth wash and keep it clean. Do not let it go it will get worse.
I am assuming you had a root canal before the crown was put on. You could be getting pain if the dentist did not take out all of the roots when he/she did your root canal. You will need to go back to the dentist and have an x-ray taken to look at your roots. Good Luck
Not all crowns have had root canals. Since there is sensitivity, it may be time for one if it wasn't done already. If it did have a root canal, it is possible that the root canal is failing and may need to be retreated. Don't assume that it is just from the root, the sensitivity may be caused by other things. When a crown is inserted, a seal is formed to prevent any further damage to the tooth. If there is sensitivity the seal may no longer be there. If that is the case you will probably need a new crown. the only way to know for sure is to see a dentist so they can xray the area and access the situation.
