Among the various dental procedures available to address dental problems, root canal treatment is one that often triggers anxiety in many people. This may be due to the longstanding myth that the procedure is extremely painful, or perhaps the term “root canal” simply doesn’t sound pleasant.
However, understanding the reasons behind needing a root canal and how is a root canal done step by step might help dispel some of the fear and reveal that it’s not as frightening as it seems.
What is a Root Canal?
Dentists often recommend a root canal to remove infected pulp and save a tooth that has been damaged or infected. This procedure helps avoid the need for tooth extraction whenever an issue arises.
The pulp, which contains nerves and blood vessels, is what keeps the tooth alive. If your dentist detects an infection in the pulp, they may suggest a root canal to prevent future infections and preserve the tooth.
So, How is a Root Canal Done Step by Step?
Step 1: Initial Consultation & Diagnosis
Your dentist will begin with an examination of your teeth and may take one or two X-rays to assess the severity of inflammation and decay. They might also conduct a sensitivity test to determine if you feel discomfort or pain when your tooth is exposed to sweet, cold, or hot substances.
Once your general practitioner identifies the source of your toothache, they may refer you to a skilled dentist for further evaluation. Endodontists, using advanced X-rays and digital imaging, will confirm whether a root canal is necessary to treat the affected tooth.
Step 2: Preparing the Area
The dentist will administer local anesthesia with a needle to numb the tooth and surrounding tissues. If the pulp is inflamed, numbing may take a little longer, but the endodontist won’t begin the procedure until the area is fully numb. Once the tooth is numbed, the dentist may place a dental dam (a rubber-like material) to isolate the infected tooth. This helps keep it dry and clean while covering the other teeth during the root canal treatment.
Step 3: Accessing & Cleaning the Roots
The dentist will then drill into your tooth to reach the root canals and pulp chamber. Using specialized tools, they clean out the pulp and thoroughly disinfect the canals with an antibacterial and antiseptic solution. This step is performed to remove bacteria and treat the infection within the canals.
Step 4: Shaping the Canals
The space where the pulp once was in the center of the tooth will be meticulously cleaned and expanded using small dental files, shaping the inner chamber to prepare it for a filling. The dentist or endodontist will then rinse the area with various solutions to remove any remaining pulp. Afterward, the tooth and surrounding area will be thoroughly dried before proceeding to the next step.
Step 5: Filling the Canals
After the pulp chamber is completely dry and clean, the dentist will fill the canals of your tooth with a rubber-like material called gutta-percha. This material is inserted into the canals, heated, and compressed to ensure it fits snugly against the walls. Then, adhesive cement is applied to securely seal the canals, preventing bacteria from re-entering.
Step 6: Restoring the Tooth
Most dentists recommend placing a dental crown as the final restoration. Not only does it improve the tooth’s appearance, but it also restores proper bite function. Crowns are custom-made, typically taking 2-3 weeks to fabricate. In the final step, the dentist removes the temporary filling and installs the permanent crown to complete the restoration.
What to Expect After the Root Canal
In the initial days after the procedure, mild tooth sensitivity is common and usually subsides within a week. Some patients may also notice an uneven bite, swelling, inflammation, or a reaction to the medication.
It’s a good idea to schedule a follow-up appointment to address any symptoms that may arise.
Aftercare & Recovery
- Avoid Chewing on the Treated Tooth: For the first few days after a root canal, avoid chewing or biting down on the treated tooth to prevent any damage to the temporary filling or crown. Stick to soft foods and chew from the opposite side of your mouth.
- Manage Pain & Swelling: Mild discomfort or swelling is normal after a root canal. Over-the-counter pain relievers like ibuprofen can help you manage the pain. Applying a cold compress to the outside of your face can reduce swelling.
- Maintain Good Oral Hygiene: Keep the area clean by brushing and flossing gently around the treated tooth. Avoid aggressive brushing, which can irritate the area.
- Attend Follow-Up Appointments: Attend any scheduled follow-up visits to ensure that your tooth is healing properly and that the permanent crown or filling is placed on time.
- Watch for Complications: Be mindful of any signs of complications after the root canal procedure, such as persistent pain, swelling, or a bad taste in your mouth.
Conclusion
Despite the myths and rumors, root canal treatments are effective in saving an infected tooth and restoring its function. If you’re considering a root canal, there’s no need to worry—it’s a painless procedure, especially if you know what to expect by following the step-by-step guide provided above.
Most patients leave their appointments feeling better than they did before, and it’s often worth saving a tooth that can stay healthy for a lifetime.

FAQs
How many appointments does it take to complete a root canal?
Most root canals can be completed within one to two visits. The first appointment involves removing the infected pulp. The second (and possibly third) appointment focuses on cleaning the root canal and sealing it with a crown or other filling to prevent future infections. Each session typically lasts around 90 minutes.
What happens if I ignore the need for a root canal?
Delaying a root canal treatment heightens the risk of:
- You may lose your infected tooth.
- The infection could spread to surrounding teeth.
- The infection might extend to your jawbone.
