What Happens During a Root Canal Procedure

A root canal procedure removes infected or damaged tissue from inside a tooth, cleans the inner space, and helps preserve the natural tooth whenever possible. If you have deep tooth pain, swelling, lingering sensitivity, or pain when biting, a dentist in Vaughan can assess whether the tooth’s nerve is affected. When an infection reaches the pulp, a root canal dentist in Vaughan may recommend treatment to relieve pain and save the tooth.

At Diamond Dental Centre, we help patients understand each step before treatment begins so the appointment feels less stressful and more manageable.

Step 1: Examining the Tooth

Before recommending a root canal, we need to understand what is causing your pain. Your dentist may check for:

  • Tooth decay
  • Cracks or damage
  • Swelling
  • Gum tenderness
  • Lingering sensitivity
  • Pain when biting
  • Other signs of infection

Dental X-rays may also be used to examine the tooth’s root and surrounding bone.

This step matters because not every toothache requires a root canal. Some teeth may need a filling, crown, extraction, or another treatment. If you are unsure whether a tooth can be saved, read more about when you need a root canal vs. an extraction to understand the difference.

Step 2: Numbing the Area

Root canal treatment is intended to relieve pain, not create more of it. Before the procedure begins, the area is numbed to help you remain comfortable.

If you feel nervous, let us know. Many patients experience anxiety before treatment, especially if they have been dealing with tooth pain for a while or are worried about what to expect. Our team will take the time to explain the process and answer your questions before moving forward.

Step 3: Removing the Infected Tissue

During the procedure, the root canal dentist creates a small opening in the tooth to access the inner pulp. The infected or damaged tissue is removed, and the inside of the tooth is carefully cleaned and shaped.

This step removes the source of the infection and helps reduce the pressure or pain caused by inflamed tissue inside the tooth.

Step 4: Sealing and Restoring the Tooth

After the inside of the tooth has been cleaned, it is sealed to help protect it from bacteria. In many cases, a dental crown may be recommended afterward, especially if the tooth is weakened or requires additional support for chewing.

The final restoration helps restore the tooth’s function, shape, and strength so you can use it more comfortably.
