What Is Root Canal And How We Overcome The Pain?

1. Introduction:

A root canal is a dental procedure used to treat an infected or severely damaged tooth. The tooth’s soft inner tissue, called the pulp, becomes infected when bacteria enter through cavities, cracks, or other forms of tooth damage. During a root canal, the infected pulp is removed, and the inside of the tooth is thoroughly cleaned and disinfected. The empty space is then filled and sealed with a material called gutta-percha to prevent further infection.

2. How we overcome the pain of root canal:

2.1 The main reason root canals are associated with pain is because of the inflammation and infection of the pulp. When the pulp becomes infected, it puts pressure on the nerves inside the tooth, leading to intense pain and sensitivity. Additionally, the infection can spread to the surrounding tissues, causing further discomfort and swelling.

2.2 During the root canal procedure, the dentist or endodontist (a specialist in root canal treatments) will administer local anesthesia to numb the area around the affected tooth. This anesthesia helps to alleviate pain and discomfort during the procedure. In some cases, the tooth may already be quite sensitive, and the injection of anesthesia itself can cause temporary discomfort, but it quickly subsides as the area becomes numb.

2.3 After the root canal, it is normal to experience some mild discomfort or soreness for a few days as the tissues around the tooth heal. Over-the-counter pain relievers can help manage this post-treatment discomfort. In more severe cases, your dentist may prescribe stronger pain medication for a short period.

2.4 To overcome the pain and ensure a successful root canal treatment, it’s essential to follow your dentist’s post-treatment instructions carefully.

3. Instruction you may follow on the time of treatment:

3.1 Taking prescribed medications as directed.

3.2 Avoiding chewing or putting excessive pressure on the treated tooth until it’s fully healed.

3.3 Maintaining good oral hygiene, including regular brushing and flossing.

3.4 Avoiding extremely hot or cold foods and beverages that could cause sensitivity.

3.5 Scheduling and attending any recommended follow-up appointments to monitor the healing process.

4. Steps to manage pain and discomfort during the RCT:

4.1 Local Anesthesia: 

Before starting the root canal procedure, the dentist or endodontist will administer a local anesthetic around the affected tooth. This numbs the nerves in the area, ensuring you won’t feel pain during the treatment. The injection might cause a slight pinch or discomfort, but it is quick and significantly reduces any pain during the procedure.

4.2 Sedation: 

In some cases, if the patient is particularly anxious or nervous about the procedure, the dentist might offer sedation options. Sedation can be administered orally, intravenously, or through inhalation, depending on the level of anxiety and patient preference. Sedation helps you feel more relaxed and at ease during the RCT.

4.3 Dental Dam: 

During the root canal procedure, a dental dam is placed around the tooth being treated. This rubber barrier isolates the tooth, keeping it dry and free from saliva and bacteria. It also prevents any debris from falling into your mouth, enhancing cleanliness and reducing the chance of infection.

4.4 Communication: 

An open line of communication between the patient and the dental professional is necessary. If you start to feel pain or discomfort during the root canal, you can signal the dentist using predetermined hand signals or words. They can then take a break, re-administer anesthesia if needed, or make adjustments to ensure your comfort.

4.5 Use of Rotary Instruments: 

Modern root canal procedures often involve the use of rotary instruments, which are more efficient and cause less vibration compared to traditional hand files. This can lead to a more comfortable experience during the procedure.

4.6 Expertise and Experience: 

Choosing a skilled and experienced dentist or endodontist is crucial for ensuring a successful and less painful root canal. A knowledgeable professional can work efficiently and minimize potential complications that may lead to discomfort.

4.7 Post-treatment Care: 

After the root canal, following the dentist’s post-treatment care instructions diligently is essential to minimize any residual pain or discomfort. This includes taking any prescribed medications, avoiding hard or chewy foods, and maintaining good oral hygiene.


Remember that while a root canal may have had a reputation for being painful in the past, advancements in dental technology and anesthesia have made the procedure much more tolerable. The goal of the dental team is to ensure you have a comfortable and pain-free experience throughout the root canal treatment. If you have any concerns or questions about the procedure, don’t hesitate to discuss it with the AMD Dental Clinic dentist beforehand.
