What Exactly Happens During a Root Canal? 

added on: January 16, 2024

The mere mention of a root canal can send shivers down the spine of even the bravest individuals. It’s a dental procedure often associated with pain and discomfort, but understanding what exactly happens during a root canal can help demystify this common dental treatment. Your dentist in Broomfield understands the apprehension someone may have if they’re told they need a root canal, but we’re also here to help ease those concerns. 

Why Would Someone Need a Root Canal?

A root canal becomes necessary when the soft tissue inside a tooth, known as the pulp, becomes infected or inflamed. The pulp houses the tooth’s nerves, blood vessels, and connective tissues. Infections can occur due to deep cavities, cracked or fractured teeth, repeated dental procedures on a tooth, or trauma to the face. If left untreated, a dental infection can lead to severe pain, swelling, and even the formation of an abscess.

The Root Canal Procedure

The best way to ease any anxiety associated with the news of needing a root canal is to understand the treatment as well as the outdated myths about pain and discomfort about the procedure.

  • Diagnosis and X-rays

Before initiating a root canal, your Broomfield dentist will conduct a thorough examination, including X-rays to assess the extent of the damage. This helps them pinpoint the location and severity of the infection.

  • Local Anesthesia

To ensure the patient’s comfort, your dentist will administer local anesthesia to numb the tooth and the surrounding area. Contrary to popular belief, a root canal is not a painful procedure due to the effectiveness of modern anesthesia.

  • Access Opening

Your dentist will create a small opening in the crown of the tooth to access the pulp chamber. This step allows them to remove the infected or inflamed pulp tissue – which is causing pain.

  • Cleaning and Shaping

Using specialized tools, your dentist will carefully remove the diseased pulp, clean the canals, and shape them to prepare for the filling. This step is crucial to eliminate any bacteria and prevent further infection.

  • Filling the Canals

Once the canals are cleaned and shaped, they are filled with a biocompatible material. This material seals the canals to prevent bacteria from re-entering, and it provides structural support to the tooth.

  • Sealing the Access Opening

The access opening created in the tooth’s crown is sealed with a temporary or permanent filling, depending on the dentist’s recommendation. In some cases, a crown may be recommended to strengthen the tooth further.

  • Restoration

While a root canal addresses the infection, the tooth may require additional restoration for full functionality and aesthetics. This can include the placement of a crown to protect the weakened tooth and restore its appearance.

Post-Root Canal Care

After a root canal, patients may experience mild discomfort, which can be managed with over-the-counter pain relievers. It’s essential to follow any post-operative care instructions provided by your dentist and attend any follow-up appointments. With proper oral hygiene and regular dental check-ups, a tooth that has undergone a root canal can last a lifetime.

A root canal is a dental procedure designed to save a tooth that is severely infected or inflamed. Understanding the steps involved and the reasons why someone might need a root canal can help alleviate fears and misconceptions surrounding this common dental treatment. 

If you suspect a dental infection or experience persistent tooth pain, consult with your dentist in Broomfield as soon as possible to explore appropriate treatment options and prevent further complications. Remember, modern dentistry has made significant strides in ensuring patient comfort and successful outcomes for root canal procedures.
