Demystifying Root Canals: What to Expect and How to Ensure a Smooth Procedure
Oct 27 2023

Feeling anxious about an upcoming root canal? You’re not alone, as many share this concern. However, gaining insight into the procedure can ease some of the anxiety. This article aims to clarify the root canal process and how to prepare for one.

What is a root canal?

A root canal is a dental procedure that’s performed to save a damaged or infected tooth. It involves removing the infected pulp from the tooth’s root canal system, cleaning and disinfecting the area, and then sealing it to prevent further infection. Despite the reputation, root canals are relatively painless, thanks to modern techniques and anesthesia.

Why is a root canal necessary?

A root canal becomes necessary when a tooth’s pulp is severely infected or damaged, often due to deep decay, a cracked tooth, or a deteriorating large filling. Infected pulp can result in intense pain, sensitivity to temperature, swelling, and abscesses. Opting for a root canal procedure is preferable to tooth extraction as it preserves the natural oral structure, prevents neighbouring teeth from shifting, and avoids potential complications like difficulties in chewing and speaking, facial structural changes, and the need for future dental work.

Signs and symptoms that you may need a root canal

Signs you might need a root canal include:

  1. Persistent Pain: If you have constant tooth pain, especially when chewing or applying pressure, it could indicate an infected pulp requiring a root canal.
  2. Sensitivity: Long-lasting sensitivity to hot or cold temperatures even after the source of the change is removed can suggest an infected tooth pulp.
  3. Swelling: Swelling around the affected tooth or nearby gums may signal an infection needing a root canal.
  4. Tooth Discolouration: A notably darker or grayish tooth colour can be a sign of infection reaching the tooth pulp.
  5. Gum Issues: Tender or swollen gums around a specific tooth, along with a small bump or pimple-like abscess, could mean the need for a root canal.

How to prepare for a root canal procedure

Preparing for a root canal procedure requires both physical and mental readiness. Here are some tips to help you prepare:

  1. Discuss Your Concerns: If you’re anxious or have questions about the procedure, discuss them with your dentist for information and reassurance.
  2. Arrange Transportation: Since a root canal involves anesthesia, it’s wise to have someone drive you home afterward for safety and comfort, as you may feel groggy or disoriented.
  3. Follow Pre-Procedure Instructions: Your dentist may give you specific instructions before the root canal, such as avoiding certain foods or medications, fasting, or adjusting your dental hygiene routine. It’s crucial to follow these guidelines for a successful procedure.

Pain management after a root canal

Following a root canal procedure, it’s typical to encounter some discomfort and sensitivity, although the level of pain varies between individuals and has been notably reduced by modern techniques and anesthesia. Here are tips for managing pain and aiding healing after a root canal:

  1. Follow Prescribed Medication: Take any pain medication or antibiotics prescribed by your dentist as directed to manage pain and prevent infection.
  2. Use Cold Compresses: Applying a cold compress to the affected area can reduce swelling and ease discomfort. Wrap an ice pack or frozen vegetables in a cloth and apply it to your cheek for 10-15 minutes at a time.
  3. Avoid Hard or Sticky Foods: Prevent further irritation to the treated tooth by refraining from biting or chewing hard or sticky foods immediately after the root canal. Opt for soft, easy-to-chew foods until the area heals.
  4. Maintain Oral Hygiene: Good oral hygiene is essential for the procedure’s success and overall oral health. Gently brush your teeth twice a day, floss regularly, and rinse your mouth with a mild saltwater solution to support healing and cleanliness in the area.


With the right information and a skilled dental professional, you can expect a successful and comfortable root canal experience.  Remember, a root canal is frequently the most effective way to save a damaged or infected tooth, ensuring your oral health and smile restoration.
