How Long Does a Root Canal Take

A root canal might sound daunting, but it’s a crucial procedure designed to save your natural teeth from severe damage or infection. This detailed guide walks you through every step of the root canal process, from understanding its benefits and potential risks to what you can expect during and after the procedure.

On average, a standard root canal procedure typically takes about 90 minutes to 2 hours. This includes the time needed for the dentist to diagnose the issue, administer anesthesia, perform the root canal, and ensure the tooth is appropriately sealed.

What Is A Root Canal?

Root canal treatment is a common and safe procedure used to treat infections in the innermost layer of teeth, known as the pulp. This treatment, which involves removing the infected tissue, cleaning the inside of the tooth, and sealing it, is essential for saving natural teeth and relieving pain. With over 15 million root canals performed annually in the U.S., the procedure is typically done by either a dentist or an endodontist, a specialist in dental pulp and pain management.

Endodontists have additional training focused on diagnosing and managing pain, making them well-equipped to handle root canal treatments. The procedure is necessary when the tooth’s pulp, containing nerves and blood vessels, becomes infected or damaged, causing significant discomfort. Despite its reputation, a root canal is a straightforward process aimed at eliminating infection and preserving the tooth’s structure.

Signs You May Need A Root Canal

Experiencing a persistent, throbbing toothache that worsens with pressure or chewing is a key indicator that you might need a root canal. This discomfort often accompanies heightened sensitivity to hot or cold, where the sensation lingers even after the stimulus is gone. 

Other warning signs include swelling or tenderness in the gums around a specific tooth, a noticeable change in the tooth’s color, and the appearance of a pimple-like bump on the gums near the affected area. If you notice any of these symptoms, it’s important to consult your dentist quickly to determine if a root canal is required.

What Are Signs I May Need A Root Canal?

  1. Persistent Tooth Pain: If you’re enduring deep, unrelenting tooth pain that radiates to your jaw or other teeth, it might be due to an infection requiring a root canal.
  1. Pain from Pressure: Sensitivity or pain when eating or touching the tooth can signal nerve damage, often associated with tooth pulp infection.
  1. Swollen Gums: Inflamed or tender gums around a tooth could indicate an underlying infection that necessitates root canal treatment.
  1. Gum Pimples: A pimple-like bump on your gums, especially if it releases foul-smelling pus, suggests a serious infection affecting the tooth.
  1. Jaw Swelling: Swelling in the jaw can occur if pus from an infected tooth fails to drain properly, highlighting the need for treatment.
  1. Discolored Tooth: A tooth may darken if the infection disrupts the blood flow, leading to a noticeable color change that could mean a root canal is necessary.
  1. Loose Tooth: Infection-induced pus can weaken the bone structure supporting your tooth, making it feel loose and requiring professional evaluation.

Before Treatment Begins

  • Gather Insurance Information: Ensure you have your insurance details ready before your appointment to avoid any administrative delays.
  • Review and Inspect: Your dentist or endodontist will start by reviewing any previous X-rays and visually inspecting the affected tooth.
  • Numb the Area: A local anesthetic will be administered with a small needle to numb the tooth and surrounding gums, minimizing discomfort during the procedure.
  • Place a Dental Dam: A rubber sheet, known as a dental dam, will be positioned over the tooth to keep it clean and isolated throughout the treatment.
  • Conduct Preliminary Tests: Tests may include tapping the tooth, applying temperature changes, or using an electric pulp tester to assess the condition of the tooth pulp.
  • Prepare for the Procedure: A tiny hole will be drilled into the tooth to access the pulp chamber, where nerves and tissues will be removed.
  • Clean and Seal: The tooth will be cleaned, disinfected, and filled with gutta-percha. A temporary filling will be placed, and a dental crown will be added later to restore and protect the tooth.

During Root Canal Treatment

  1. Create an Access Point: Your dentist or endodontist will use a drill to open the top of the tooth, exposing the pulp chamber where the infection resides. This step is crucial for accessing the damaged tissue inside the tooth.
  1. Remove the Pulp: The infected or damaged pulp, including nerves and blood vessels, will be carefully extracted from the tooth’s interior. This process is central to addressing the infection and alleviating pain.
  1. Clean and Shape the Canals: The emptied root canals will be cleaned and shaped using small files. Irrigating solutions will be used to flush out any remaining debris, and the area will be thoroughly dried to prepare it for filling.
  1. Apply Antimicrobial Medication: An antimicrobial medication will be applied to the canals to prevent or treat any lingering infection. If the infection is severe, the tooth might be left open temporarily to drain.
  1. Fill the Canals: Once the canals are clean and dry, they will be filled with gutta-percha, a rubber-like material that seals the tooth and helps prevent future infections.
  1. Seal with Temporary Filling: A temporary filling will be placed to protect the tooth until a permanent restoration can be fitted. In some cases, a permanent filling may be applied during the same visit.
  1. Schedule a Follow-Up: A dental crown will be required to fully restore the tooth’s function and appearance. This might involve a follow-up appointment to fit the crown, which typically takes two to three weeks.

How Long Does A Root Canal Take?

A root canal usually takes longer than a standard filling due to the comprehensive process involved. This includes not only anesthesia and preparation but also the removal, cleaning, and sealing of the tooth’s nerve. For most straightforward cases, the procedure can be completed in a single visit lasting between 30 minutes to just over an hour. However, complex situations, such as those involving multiple canals or severe infections, might extend the time to 90 minutes or necessitate a follow-up appointment.

The duration of a root canal largely depends on the type and number of tooth roots being treated. Canines and incisors, with their single root, are generally quicker to address. Premolars, having one or two roots, can take an hour or more. Molars, with up to four canals, often require 90 minutes or more. Recovery from a root canal is typically swift, usually under a week, but persistent pain should be discussed with your dentist.

After your root canal, treat the area with care. Initially, avoid chewing on the treated tooth until the numbness fades. Start with soft foods to prevent discomfort. Some sensitivity or mild pain is normal and can be managed with over-the-counter pain relievers. If pain or swelling persists, contact your dentist. You may need antibiotics to tackle any remaining infection. 

Follow-up is essential. During this visit, your dentist will replace the temporary filling with a permanent one or prepare the tooth for a crown. The choice depends on the tooth’s condition and location. After restoration, maintain good oral hygiene by brushing twice daily, flossing, and attending regular dental check-ups. Root canals are now routine and generally comfortable, aimed at saving your tooth and ensuring its health for years to come.

Who Performs A Root Canal?

Root canal procedures can be handled by either general dentists or endodontists. Endodontists are specialists with advanced training in dental pulp and root issues. Their expertise includes managing pain and performing intricate procedures to preserve natural teeth. They are often the go-to professionals for complex cases.

Many general dentists are also skilled in performing root canals as part of their broad dental training. Choosing between a general dentist and an endodontist depends on the complexity of your case and personal preferences. For routine procedures, a general dentist is often sufficient, while more challenging cases might benefit from the specialized care of an endodontist. Open communication with your provider will help ensure you receive the best treatment.

Most Root Canal Procedures Will Follow These Steps

  • Numbing the Area: The dentist or endodontist applies numbing medication and injects a local anesthetic to ensure the tooth and surrounding gums are pain-free.
  • Accessing the Pulp: Once numb, a small hole is drilled into the top of the tooth to reach the infected pulp. The pulp and inside of the tooth are then cleaned and treated with an antibiotic to prevent further infection.
  • Sealing the Tooth: The cleaned tooth is filled with a paste or synthetic material and covered with a temporary filling to protect it.
  • Final Restoration: A follow-up visit may be required to place a permanent filling or crown, completing the restoration of the tooth.

After the procedure, you might experience some soreness or numbness, but this usually lasts only 24-48 hours and can be managed with over-the-counter painkillers. Most patients resume their normal activities on the same day, finding the discomfort from the procedure far less than the pain caused by the infected tooth.

After a root canal, your provider might recommend a brief rest before you leave the office. Anesthesia can take up to an hour to fully wear off, so your mouth may feel numb for a while. Some people prefer to relax at home during this period, while others continue with their daily activities.

You’ll usually need two follow-up visits: one to prepare your tooth for a dental crown and another to place it. These steps ensure your tooth is fully restored and protected.

How Long Does It Take To Heal?

Healing from a root canal is generally straightforward. While the procedure itself is not more painful than a typical dental filling, you might feel some soreness and sensitivity for a few days. This discomfort is usually minor and manageable.

What Happens If My Root Canal Fails?

Root canal failures are uncommon, impacting only about 5% of cases. If a root canal doesn’t succeed, there are effective alternatives for saving your tooth. One option is endodontic retreatment, where the old filling is removed, the canal is cleaned, and the tooth is refilled and resealed. Another approach is an apicoectomy, which involves removing the infected tissue from the tooth’s root and sealing it.

In some cases, a root canal may not address the underlying problem, especially if the tooth is extensively damaged. Should a root canal fail, your dentist will explore other solutions. These may include performing another root canal or opting for extraction followed by a dental implant or bridge.

What Are The Potential Benefits Of Root Canals?

Root canals effectively eliminate infections that, if ignored, could lead to more severe problems such as spreading infections to other teeth or damaging the jawbone. By addressing the infection, root canals help preserve your natural tooth and prevent potential complications that could affect your overall oral health.
