What Does Tooth Pain Under Crown Mean If It Comes and Goes?

Dec 30, 2023 | Blog, Crowns

No one wants to be stuck nursing tooth pain after getting a crown. It’s even worse when the pain seems to go away, only to hit you again, coming at you with full force. But while this is not that uncommon, constantly experiencing pain under your crown can be a cause for concern. So, if you’re also suffering from tooth pain under a crown that comes and goes, don’t worry, you’re not alone! In this blog, we’ll break down all the causes behind the pesky toothache and the different ways to help relieve it.

What is a Dental Crown?

A dental crown is a cap-like oral device that is placed over a decayed or damaged tooth in order to protect it. The main purpose of a crown is to serve as a barrier, sealing the damaged tooth under its cover. However, rather than alter the appearance of your teeth, dental crowns mimic the natural shape, color, and size of your teeth. This way, once the crown is bonded to the tooth, it’s difficult to tell it apart from the rest since it doesn’t just look natural but also functions like a real tooth.

What Causes Tooth Pain Under Crown That Comes and Goes?

There are many reasons that can give way to tooth pain under a crown. But if the pain keeps coming and going, it could be due to the following causes.

1. Tooth Decay

One of the major reasons for tooth pain under a crown is tooth decay. Even though a crown cannot decay, the tooth underneath is susceptible to damage. Whether the bacteria wasn’t completely removed the first time around or it snuck under the edges of the crown, the pain it causes can be excruciating.

2. Oral Infection

Over time, the seal between the crown and the tooth tends to weaken, which causes bacteria to swim past that barrier and attack the tooth underneath. If the pain gets worse when you bite down on something, it’s probably because of an oral infection.

3. Fractured or Broken Crown

A fractured or broken crown exposes the underlying tooth to external stimuli, leading to pain. While it is not normal for a crown to fracture, it can break due to trauma, biting on hard objects, or even normal wear and tear over the years.

4. Tooth Sensitivity

Many people suffer from tooth sensitivity, which can sometimes worsen after getting a crown. This is because the enamel layer has to be shaved down a little to accommodate the crown. A sensitive tooth might react to everything you eat or drink with pain.

5. Gum Disease

Gum diseases don’t just affect your gums but also impact your teeth. Gingivitis and gum recession are two conditions that can trigger extreme tooth pain under a dental crown.

6. Poorly Fitted Crown

If the crown is not properly fitted, it can give way to tooth sensitivity and a lot of pain. A loosely fitted crown might feel wiggly, with random bursts of toothache that keep coming and going.

7. Bruxism

Bruxism is an oral condition that develops from the habit of constantly grinding or clenching your teeth. If you have bruxism, chances are the crown got loosened from the grinding of teeth, leading to pain.

Bottom Line

Tooth pain under a crown is not always something to worry about. However, if the pain keeps coming in waves or the tooth pain under your crown comes and goes out of nowhere, it could be a cause for concern.
