Why Does My Tooth Hurt with a Crown? Understanding the Causes and Solutions

Whether you recently got a crown or have had one for some time, it's unsettling when you begin experiencing tooth pain. This sensation, often brought on when a tooth with a crown is involved, can leave you wondering what might be the cause. Here, we explore several potential reasons for toothache with a crown and provide solutions to alleviate your discomfort.

Persistent Pain from a Tooth with a Crown

Although a crown covers the visible part of your tooth, the underlying tooth is still alive. This means tooth decay or a new cavity can form at the edge of the tooth and the crown, leading to persistent pain in the area. In cases where a cavity grows large enough to affect the nerve, you might need a root canal procedure. It's crucial to understand that roots can come into contact with nerves even after a crown is placed.
If you didn’t have a root canal prior to receiving your crown, your tooth still contains nerves. Sometimes, the pressure exerted by the crown on these sensitive nerves can lead to an infection. This situation can also occur if the area beneath the crown contains old, leaky fillings that allow bacteria to infect the nerve.
Signs of infection include pain when you bite, gum swelling, sensitivity to temperature, and fever. If you're experiencing any of these symptoms, consult your dentist immediately as these could be signs of a more serious issue, such as an infected nerve or periodontal disease.

Other Causes of Toothache with a Crown

There are several other reasons why a tooth with a crown might cause pain:

Deep Tooth Preparation

Your tooth preparation under the crown might be too deep, which could result in the nerve being exposed and causing pain. This can happen during the process of shaping the tooth to fit the crown, and it’s important to report any unusual sensations to your dentist.

Space Between Crown and Gum

There could be a gap between the crown and the gum tissue. Food impaction can occur in this space, leading to periodontal issues. Periodontitis is an inflammation of the gum tissue, which can cause pain and discomfort around the tooth with the crown.

Prevention and Solutions

While it's important to identify the cause of your toothache with a crown, it's equally crucial to approach the issue head-on to prevent further complications. Here are some steps you can take:

Improved Oral Hygiene

Maintaining a strict oral hygiene routine is essential. Regular brushing and flossing can help prevent the formation of new cavities or exacerbation of existing ones. Ensure you clean the area beneath the crown thoroughly, especially if there is a gap between the crown and the gum.

Consult Your Dentist

Visit your dentist promptly if you experience persistent pain. They might recommend a root canal procedure if the pain is due to nerve irritation. They may also adjust the crown if necessary to ensure it fits well and there is no pressure on sensitive nerves.

Consider Metal-Free Crowns

Some people opt for metal-free crowns to avoid any potential irritation from metal alloys. Speaking to your dentist about your options can help you find a solution that works best for you.

By understanding the causes and actively seeking solutions, you can manage and alleviate toothache with a crown. Remember, early intervention is key to preventing more severe dental issues.

Frequently Asked Questions

Q: Can a crown cover a nerve?
A: Typically, a crown doesn’t directly cover a nerve as it covers the visible part of the tooth. However, issues like decay under the crown or poor fit can expose or irritate the nerve, leading to pain.

Q: How can I prevent tooth decay under a crown?
A: Regular oral hygiene, including proper brushing and flossing, can help prevent new cavities. Ensure that the area beneath the crown is thoroughly cleaned to prevent food impaction and periodontal issues.

Q: When should I get a root canal?
A: You should consider a root canal if the pain is persistent and associated with nerve irritation, swelling, or other signs of infection. Your dentist can provide a more accurate assessment based on your specific condition.
