What to Expect During Root Canal Treatment

Root canal treatment (also known as endodontic therapy) is a dental procedure used to treat infections or damage inside a tooth’s pulp — the soft tissue at the centre of the tooth containing nerves and blood vessels. Though the idea of a root canal often causes concern, it is a common and effective treatment for saving a tooth that would otherwise need to be extracted. This guide will explain what you can expect during the procedure, what recovery is like, and provide post-care instructions to help ensure a smooth healing process.

The Root Canal Treatment Process

Root canal treatment is typically carried out in one or two visits, depending on the severity of the infection or damage to the tooth. Here is a step-by-step breakdown of what you can expect during the procedure:

1. Initial Consultation and Preparation
   Before starting the root canal procedure, your dentist or endodontist will assess the tooth, usually with an X-ray, to determine the extent of the infection or damage. Once they have a clear understanding of the issue, they can begin to plan your treatment.
2. Discuss your treatment plan with our care coordinator team
   Once your Dentist has developed your personalised treatment plan, our dedicated team of treatment coordinators will contact you to discuss your options. Once you are happy to go ahead, we can book your appointment for treatment.
3. Anaesthesia
   To ensure that you are comfortable throughout the procedure, a local anaesthetic will be administered to numb the area around the affected tooth. This means that you should feel little to no pain during the treatment.
4. Accessing the Tooth
   Once the anaesthetic has taken effect, your dentist will create a small access hole in the crown of the tooth to reach the pulp chamber. This will allow them to clean and remove the infected or damaged tissue.
5. Cleaning and Shaping the Root Canals
   The dentist will then carefully remove the infected pulp from the root canals using special instruments. The canals will be thoroughly cleaned and shaped to prepare them for filling. This step may take some time, depending on the number of canals and their complexity.
6. Filling the Root Canals
   After cleaning the canals, the dentist will fill them with a biocompatible material, usually a rubber-like substance called gutta-percha. This material seals the canals to prevent bacteria from re-entering the tooth. In some cases, a temporary filling may be placed to allow the tooth to heal before the final restoration.
7. Placing a Permanent Filling or Crown
   Once the root canals have been filled, your dentist will place a permanent filling or a crown to restore the function and appearance of the tooth. A crown is often recommended, especially for teeth that are heavily damaged or at risk of further fracture. The crown helps to protect the tooth from further damage and ensures its stability.

Root canal treatments are usually completed in a number of stages across a number of appointments. This is to ensure that the tooth has completely settled prior to placing the final filling inside of the canal spaces.

Recovery Time and What to Expect After Root Canal Treatment

Root canal treatment is generally well-tolerated, and most patients recover quickly with minimal discomfort. Here is an overview of what to expect during the recovery process:

1. Anaesthesia Wearing Off
   After the procedure, the anaesthesia will gradually wear off, and you may experience some mild discomfort or soreness in the treated area. This is completely normal and typically resolves within a few hours. Some swelling or tenderness in the gums around the treated tooth is also common but should subside within a day or two.
2. Post-Treatment Sensitivity
   It is common to experience some sensitivity in the tooth for a few days following root canal treatment, especially when chewing or when the tooth is exposed to hot or cold temperatures. This sensitivity usually diminishes over time as the tooth heals. If you experience persistent or severe pain, this could be a sign of ongoing issues, and you should contact your dentist.
3. Mild Discomfort or Tenderness
   There may be mild discomfort in the surrounding gum tissue or jaw, especially if the root canal was due to an infection. This discomfort typically goes away after a few days. In some cases, your dentist may recommend over-the-counter pain relievers, such as ibuprofen or paracetamol, to manage any discomfort.

Post-Care Instructions for Root Canal Treatment

Proper aftercare is important to ensure that the tooth heals properly and to minimise the risk of complications. Here are some key post-care instructions following root canal treatment:

1. Avoid Chewing on the Treated Tooth Immediately
   For the first 24 hours after treatment, avoid chewing on the tooth that has been treated, especially if a temporary filling is in place. Chewing on the treated tooth too soon can cause the temporary filling to dislodge or lead to further irritation.
2. Be Gentle with Brushing and Flossing
   You can continue to brush and floss your teeth but be gentle around the treated area. Avoid brushing the area too vigorously, as it may be sensitive. Stick to a soft-bristled toothbrush and floss carefully to avoid irritating the gums.
3. Manage Discomfort with Pain Relievers
   If you experience mild pain or discomfort after the procedure, over-the-counter pain relievers such as paracetamol or ibuprofen can help. Be sure to follow the recommended dosage instructions on the label. If pain persists, contact your dentist for further advice.
4. Avoid Hard, Crunchy, or Sticky Foods
   After root canal treatment, it is best to avoid hard, crunchy, or sticky foods for a few days, particularly if you haven’t yet received a permanent filling or crown. These types of foods could put unnecessary pressure on the treated tooth, potentially causing damage or dislodging any temporary restorations.
5. Follow-Up Appointments
   You will likely need a follow-up appointment to check the healing progress of the treated tooth and ensure that the root canal has been successful. If a crown is required, this appointment will also include discussions of the permanent restoration.
6. Watch for Signs of Infection
   While root canal treatment is highly effective, there is a small chance that the infection could return. If you notice any of the following symptoms, contact your dentist immediately:
   • Persistent pain or swelling
   • A pimple-like bump on the gums (a sign of infection)
   • Prolonged sensitivity to hot or cold temperatures

Root canal treatment is in the majority of cases a highly effective procedure for saving a tooth that has been severely damaged or infected. While the idea of the procedure can be worrying, it is generally straightforward and well-tolerated, with most patients experiencing little discomfort. By following the post-care instructions provided by your dentist and attending any follow-up appointments, you can ensure that your treated tooth heals properly and continues to function as part of your healthy smile.

If you have any concerns or experience unusual symptoms after your root canal treatment, do not hesitate to contact your dentist for advice. Your oral health is important, and with proper care, your root canal-treated tooth can last for many years to come.
