Are Root Canals Painful? Myths vs. Reality Explained

Root canals have long been misunderstood, often evoking fear and anxiety in patients. Many believe the procedure is excruciatingly painful, while others assume extraction is a better alternative. However, modern root canal treatments are designed to be as pain-free and effective as possible, thanks to advancements in dental technology and anaesthetic techniques. In this article, we’ll debunk common myths, explain the reality of root canal therapy, and provide valuable insights into the procedure. 

What is a Root Canal and Why is it Necessary? 

A root canal is an endodontic treatment that involves removing infected or damaged pulp from the tooth’s interior, cleaning and disinfecting the root canals, and sealing them to prevent further infection. This procedure is necessary when a tooth’s nerve becomes inflamed or infected due to: 

• Deep decay (untreated cavities) 

• Repeated dental procedures on the same tooth 

• Cracks or fractures in the tooth 

• Trauma or injury 

• Abscess formation 

Ignoring a severely infected tooth can lead to complications such as severe pain, swelling, and even tooth loss. A root canal aims to preserve the natural tooth, preventing the need for extraction and costly replacements. 

Do Root Canals Hurt? Myths vs. Reality 

Myth 1: Root Canals Are Excruciatingly Painful 

Reality: One of the most persistent myths surrounding root canals is that they cause severe pain. In reality, modern root canal treatments are virtually pain-free due to the use of local anaesthesia and sedation options. Patients typically experience only mild discomfort, similar to receiving a standard dental filling. 

Myth 2: Extraction is Better Than a Root Canal 

Reality: Many people believe that removing a damaged tooth is a better solution than undergoing a root canal. However, keeping your natural tooth is always preferable. Extraction leads to: 

• Bone loss in the jaw 

• Shifting of adjacent teeth 

• The need for costly replacements, such as implants or bridges 

• Possible changes in speech or chewing ability 

A successful root canal preserves the natural structure of the tooth, allowing for normal function. 

Myth 3: Root Canals Cause Illness 

Reality: There is no scientific evidence linking root canals to systemic diseases. The misconception originates from outdated research from the early 20th century, which has since been debunked by leading dental and medical organisations. 

Myth 4: The Procedure Takes Multiple, Lengthy Appointments 

Reality: With advancements in endodontic treatment, most root canals can be completed in a single visit. However, complex cases may require two visits for thorough cleaning and proper sealing of the tooth. 

Myth 5: Root Canal Pain Lasts for Weeks 

Reality: While some mild soreness is expected after the procedure, it typically subsides within a few days and can be managed with over-the-counter pain relievers such as ibuprofen or paracetamol. 

What Happens During a Root Canal Procedure? 

A root canal treatment involves several steps to ensure complete removal of infection and proper restoration of the tooth: 

1. Diagnosis and X-rays: The dentist examines the tooth and takes X-rays to assess the infection. 

2. Local Anaesthesia: A numbing agent is administered to ensure a painless procedure. 

3. Pulp Removal: The dubbo dentist drills a small opening in the tooth and removes the infected pulp. 

4. Cleaning and Disinfection: The root canals are thoroughly cleaned and disinfected. 

5. Filling and Sealing: The cleaned canals are filled with a biocompatible material (gutta-percha) and sealed. 

6. Restoration: A dental crown or filling is placed to restore the tooth’s function and appearance. 

How Does a Root Canal Compare to Tooth Extraction? 

Factor	Root Canal	Tooth Extraction
Pain Level	Mild discomfort with anaesthesia	May cause more post-op pain
Procedure Time	1-2 visits	1 visit, but replacement may take months
Healing Time	A few days to a week	Weeks to months (if an implant is needed)
Cost	Cost-effective in the long run	Replacement adds to the overall cost
Preserves Tooth?	Yes, maintains natural function	No, requires artificial replacement

How to Care for Your Tooth After a Root Canal? 

• Pain Management: Take OTC pain relievers such as ibuprofen. 

• Oral Hygiene: Continue brushing and flossing as usual but be gentle around the treated tooth. 

• Avoid Hard Foods: Stick to soft foods until the tooth fully recovers. 

• Follow-Up Visit: Attend any scheduled appointments to ensure proper healing. 

• Watch for Complications: Contact your dentist if you experience severe pain, swelling, or prolonged sensitivity.
