A dental crown is a great tool to improve a smile. Dental Crowns can help strengthen a weak or damaged tooth, they can help hide the discolored teeth and can help fill the gap left by missing teeth. When you get a dental crown, it is common to experience sensitivity. Usually, it goes away in a couple of weeks, however, in some cases it may persist longer. Many factors can contribute to persistent crown-sensitivity, some of the important ones are discussed below.

A Disturbed Nerve
If you find your tooth sensitive to cold even after a couple of weeks of getting a dental crown, it is possible that the filling under your dental crown is disturbing the nerve inside your tooth. The resulting reaction may be causing the annoying sensitivity. If this persists, a root canal may be needed.
A Wrong Bite
The placement of a dental crown is crucial. The upper and lower teeth must meet each other properly when you close your teeth. If the placement or size of the crown is off, you may get bite-tenderness and consequently sensitivity and pain.
The Temporary Crown
Often times a dentist will place a temporary dental crown before moving on to a permanent one. If the temporary crown is made of metal, it may transmit hot or cold to the inside of your teeth, causing sensitivity. A permanent dental crown may solve this problem.
The Tooth under the Crown
The condition of the tooth that has been covered by the crown may be the root cause of your sensitivity. If the filling is placed too close to the nerve, the nerve may react. Similarly, if the cavity is not properly filled in, tooth might still be decaying, making it sensitive and painful.
If the dental crown is not properly placed, it may not cover the roots of your tooth properly. A bad crowning procedure may also lead to receding gums, which do not only cause sensitivity but also some serious gum diseases.
We hope that this information will help you better understand crown sensitivity. For optimal oral health, it is important to choose your dentist smartly and visit him regularly.
