Do you experience tooth pain under the crown that often comes and goes? Some people believe they won’t experience any discomfort once they get a dental crown. But this is far from the truth. Your tooth under a crown is as prone to dental ailments as other teeth. There are several factors that can cause tooth pain, sensitivity, or bite issues after placing a crown. Let’s look at 5 common reasons you can experience tooth pain under a crown. 

5 Common Reasons Why People Can Experience Tooth Pain Under The Crown

1. Cavity

Some patients assume that they can no longer get a cavity once they have a dental crown. However, you may develop a cavity due to improper hygiene if the tooth under a crown is still alive. Dental plaque buildup can cause tooth decay and cavity if you don’t treat it promptly. It can also damage and infect your tooth under a crown. Your best bet is to follow a good oral hygiene routine and routine dental visits to avoid cavities altogether.

2. Infection

If you have an infection and didn’t undergo a root canal before placing a crown, your tooth can still have nerves in it. This might put pressure on an infected nerve, causing pain that comes and goes. Other times, you can get an infection because of leakages in your old fillings. This can also cause nerve infection under your crown. How do you know you have developed an infection under a crown? Look for the following symptoms:

Pain when biting


Gum swelling

Tooth sensitivity  

3. Tooth Fracture 

A trauma to your face can crack the crown or the tooth under a crown, which can cause discomfort and mild pain. Because of the crack, you may experience tooth sensitivity. If this is the case for you, you should visit your dentist in Humble, TX, right away.

4. Gum Recession

You can experience tooth sensitivity in your crown tooth if you have a receding gum line. This might result from forceful tooth brushing or dental plaque buildup. How do you know whether your gum line is receding? Check your crowned tooth and notice if there’s a yellow area next to your white crown. You may require a replacement crown if this is the case for you.

5. Improper Fit

Crowns that don’t fit properly can cause tooth pain. An improper fit can also impact your bite and smile. A dental crown must fit perfectly to your bite, similar to your other teeth. If you feel something wrong when you bite, let your dentist know before it leads to TMJ disorder and headaches.


The crown shouldn’t cause tooth pain. But if it does, it might be due to an infection, a cavity, tooth fracture, improper fit, or gum recession. It’s advisable to act promptly if you experience frequent intervals of tooth pain. For more information, please contact Lonestar Dental. Our team of professionals is ready to help you!
