Hello.

At The Square Dental Clinic, we aim to provide

specialized knowledge based on the latest insights,

When tooth decay is deep or a crack develops in a tooth,

we undergo “crown treatment,” in which a prosthetic restoration resembling a crown is placed over the tooth to protect it.

However, there are times when pain develops after crown treatment, which can leave patients feeling confused and concerned.

The prosthetic restoration itself is made of artificial material and therefore cannot feel pain,

but pain may be felt after crown treatment depending on the condition of the dental nerve inside the tooth covered by the restoration and the relationship between the upper and lower teeth when they meet.

In this column,

we will take a look at

the reasons why pain develops

after crown treatment

and the possible solutions. :)

Pain after crown treatment,

(1) Nerve irritation may be the cause.

The first possible cause of pain after crown treatment is “nerve irritation.”

Crown treatment does not necessarily mean that root canal treatment must also be performed.

  • Even if tooth decay is present, the nerve may not be exposed, or

  • the patient may wish to preserve the nerve as much as possible.

In such cases, a crown may be placed without root canal treatment.

To place a crown over a tooth,

it is necessary to extensively trim the existing tooth to create enough space...

During this process, the living nerve inside the tooth may receive strong stimulation, resulting in pain.

The tooth generally gradually adapts over time,

but if the pain continues even after about a month, root canal treatment may ultimately be necessary.

Pain after crown treatment,

(2) Accessory canals and inflammation may be involved.

The second possible cause is a problem involving accessory canals or inflammation.

Many people ask, “Why does it still hurt if the nerve was removed through root canal treatment?”

Root canal treatment does not kill the nerve.

Rather, it involves thoroughly removing and disinfecting the microscopic nerve and blood vessel tissues inside the contaminated tooth.

A tooth can contain three to four canals, and the tiny canals branch out like tree roots and become intricately intertwined in a network.

In other words, residual nerve tissue or chronic inflammatory material may remain in tiny canals that are difficult to identify with the naked eye,

stimulating the bone tissue and causing pain.

Because this is not a defect in the prosthetic restoration,

it is possible to identify the exact cause of the problem and consider retreatment of the root canal, among other options.

Pain after crown treatment,

(3) Your bite should be checked.

The third possible cause may be related to the bite, or occlusion.

Zirconia or ceramic restorations, which are often used for molars, can concentrate shock and pressure on the tooth root and periodontal ligament if their height does not match that of the surrounding teeth, even by a very small amount.

The root may throb as the repeated impact feels as though you are chewing on a stone.

Fortunately, this problem can be resolved through a simple bite adjustment at the dental clinic.

In addition, if food debris or plaque becomes trapped along the boundary between the crown and the gums and causes inflammation,

this may also become a source of pain, so careful oral hygiene is important.

As crown-related pain can involve several interrelated problems,

we recommend choosing a dental clinic with specialists in integrated dentistry who can carefully address complex inflammation inside the tooth,

as well as orthodontic specialists who can correct subtle differences in the height of the prosthetic restoration and balance the overall bite,

so that diagnosis and treatment can be performed from multiple perspectives.

This article was written for those who may have felt troubled by pain in an area where crown treatment had been completed.

Here is a summary of the key points covered today.

1️⃣ If a crown was placed without root canal treatment, nerve irritation may cause pain.
2️⃣ If there is pain after root canal treatment, it may be caused by accessory canals or residual inflammation.
3️⃣ If the tooth throbs when you bite, the cause may be a bite problem.

Rather than enduring the pain and feeling anxious on your own, please visit a dental clinic for an accurate diagnosis.
