Root Canal Crown, Undergoing a root canal treatment is a significant step towards saving a damaged or infected tooth. However, many patients are surprised to learn that a tooth crown is often recommended following this procedure. This additional step may seem unnecessary at first, but it plays a crucial role in ensuring the long-term health and functionality of your tooth.

Moreover, many crowned teeth end up getting root canal treatment done as well. This article will explain more about dental crowns, root canal treatments, and the relationship between both.

What is a root canal treatment?

Our teeth contain nerves, blood vessels and enamel. When a tooth has extensive cavities or becomes damaged due to an accident, the nerves and blood vessels become extra sensitive. In some cases, this tooth can be restored with some filling, but if the situation persists, the pulp tissue eventually becomes inflamed.

The result is severe pain in the tooth which does not go away even with medication. To save the tooth from extraction, a root canal treatment is performed. This procedure removes any inflamed or infected nerve tissue, thereby stopping the pain. The success of root canal treatment lies in its ability to alleviate pain and save the tooth.

When do I need root canal treatment?

  • Pain: Patients experience severe and continuous pain and in some cases make an emergency visit to the dentist due to the excruciating pain. Patients may feel this pain whenever they bite into food as well.
  • Swelling: Inflammation of the tissues can lead to swelling around the affected tooth.
  • Pus: In some cases, pus can ooze out of the tissues surrounding the damaged tooth.
  • Loose tooth: When the infection travels to the structure supporting the damaged tooth, the tooth becomes destroyed. When this happens, this tooth becomes loose and may fall out if treatment is not sought in time. You should visit a dentist right away if you experience any of these symptoms.

What is a crown?

A crown is a dental cap that covers a whole tooth to protect it. There are various types of crowns, and they all aim to restore the tooth to its original shape and protect it from further damage.

Why do we need a dental crown after a root canal?

Root canal treatment effectively removes the infected or damaged pulp from inside your tooth, but it can leave the tooth fragile and vulnerable. The following reasons are typically why a dental crown after a root canal is necessary:

  1. Protection: The procedure removes a significant amount of tooth structure, weakening the tooth. The tooth also becomes more brittle after a root canal. A crown covers the tooth, protecting it from fractures and further damage.
  2. Improved tooth appearance: A tooth after root canal treatment may become discoloured. In such instances, crowns are used to cover up the discolouration and to improve the look of the patient’s smile.
  3. Restores function: A crown restores the tooth’s original shape and function, allowing you to bite and chew effectively. This is essential for maintaining proper oral function and avoiding discomfort.
  4. Sealing: The crown provides an additional seal, preventing bacteria from re-entering the tooth and causing reinfection.
  5. Durability: Filling materials used in root canals can wear down over time. A crown offers a more durable solution, extending the life of the tooth.

Is a dental crown after root canal treatment necessary?

Crowns are mainly used to protect and restore damaged teeth. Before the crown is installed, it’s ideal that anything that compromises the tooth’s nerve tissue is removed. As such, if the tooth is significantly damaged, it’s better to perform a root canal treatment first to ensure any infection is removed. In most cases, the events that lead to the need for a crown also require a need for root canal treatment too.

Otherwise, if you’re getting a crown purely for aesthetic reasons or if your tooth is not acutely infected or inflamed, a root canal treatment will not be needed. Typically, teeth that undergo root canal treatment will require crowns afterward for protection. This is especially so for teeth in the back, or molars and premolars. Front teeth, incisors and canines may not require a crown. Your dentist will be able to advise better.
