Understanding the Basics of Root Canal Treatment: What You Need to Know

Updated: Sep 19

What is Root Canal Treatment?

If you have pain or an infection in a tooth, there are usually two main treatment options: removing the tooth or saving it with a root canal treatment. A root canal, also known as endodontic treatment, focuses on saving your natural tooth, which is almost always the preferred option.

The goal of root canal treatment is to:

  1. Remove the infected, inflamed, or dead tissue from inside the tooth.

  2. Clean and disinfect the root canal space.

  3. Seal the space to prevent future infection.

Why is Root Canal Treatment Important?

By removing the infection and sealing the tooth, a root canal can relieve pain, eliminate infection, and restore the tooth’s function without needing to remove it. This is why root canal treatment is a highly effective and necessary option when it comes to saving your tooth.

The process usually takes 2-3 appointments, spaced over a few weeks. During the first visit, the dentist will remove the infected tissue, relieve any pain, and apply antibacterial medication. Over the next visits, the root canals are cleaned, filled, and sealed to keep bacteria out. Once the treatment is complete, a crown or filling is placed on the tooth to protect and strengthen it.

Signs You May Need a Root Canal





Sometimes, a dentist may detect the need for a root canal through an x-ray during a routine check-up, even if you’re not feeling any pain. However, common signs of an infected tooth include:

  • Persistent toothache or pain in the jaw

  • Throbbing pain that wakes you at night

  • Sensitivity to hot or cold

  • Swelling of the face or gums

  • A bump or pimple on the gum near the tooth

  • Pain when biting or chewing

  • Tooth discolouration (turning brown or gray)


If you experience any of these symptoms, it's essential to see your dentist. Early treatment can save your tooth and prevent further complications.


The Importance of Routine Dental Care

Regular dental check-ups, typically every six months, can help prevent the need for more serious treatments like a root canal. Your dentist can spot potential issues early on, ensuring your teeth stay healthy and pain-free.
