What Is Root Canal Treatment?

What Is Root Canal Treatment?

Root canal therapy (also called Endodontics) is needed when the pulp inside a tooth becomes infected — usually due to:

  • Deep decay

  • A cracked or broken tooth

  • Trauma or injury

  • A failed filling or restoration

If left untreated, the infection can spread to surrounding tissues and cause a dental abscess, swelling, and severe pain. A root canal can stop the infection in its tracks — and save your natural tooth.

Signs You May Need a Root Canal

Signs You May Need a Root Canal

  • Persistent toothache or throbbing pain

  • Sensitivity to hot or cold that lingers

  • Pain when biting or chewing

  • Swollen gums or facial swelling

  • Darkening of the tooth

  • A pimple or bump on the gum near the tooth

If you’re experiencing any of these symptoms, contact us right away. Prompt treatment can prevent the need for extraction.

How Root Canal Treatment Works

  • Diagnosis & Local Anaesthetic
    We begin by taking an X-ray to assess the extent of infection. Local anaesthetic is used to numb the area, so the procedure feels similar to having a filling.

  • Cleaning the Canal
    The infected pulp is removed, and the inside of the root canal is thoroughly cleaned and disinfected using specialist tools.

  • Filling the Canal
    Once clean, the space is filled with a special material to seal the tooth and prevent future infection. A temporary filling is placed, and the tooth is left to settle.

  • Final Restoration
    At a follow-up appointment, we assess healing. Once the infection is fully cleared, the tooth is permanently filled or restored with a crown for long-term protection and strength.

🕒 Note: Root canal treatment often takes two or more appointments, depending on the severity of infection and condition of the tooth.

Will It Hurt?

Thanks to modern techniques and local anaesthetic, a root canal is no more uncomfortable than a regular filling. Most patients are surprised at how smooth and pain-free the experience is.

Questions you may have about this treatment

Root canal or endodontic treatment treats the inner part of your tooth when the pulp is infected or inflamed. The inflammation or infection may be the result of: deep tooth decay, repeated dental procedures on faulty crowns, chips or cracks in the tooth. Dental trauma to a tooth may lead to pulp damage even though the tooth does not have visible cracks or chips. If pulp inflammation or infection is not treated on time, then this may lead to pain or abscess.

During root canal treatment, the infected or inflamed pulp is removed and then the inside of tooth is cleaned and disinfected carefully. After this, it is filled and sealed by using a rubber-like material known as gutta-percha. Afterwards, the tooth will be restored with a filling or crown for added protection. Once the restoration is done, the tooth will function like a natural tooth.

Endodontists are dental specialists who have attained two or more years of specialised training in a dental school. Many root canal specialists use state-of-the-art technology like digital imaging, ultrasonic instrumentation, fiber optics and operating microscopes for treating patients comfortably and predictably.

Root canal therapy is not anymore uncomfortable than a filling. Rather, the procedure doesn’t involve much pain and the latest advances have made it virtually pain-free. Endodontists know how to deal with pain and by using modern techniques; the majority of patients have reported that they have felt comfortable during the treatment.

No. Although X-rays are necessary during the endodontic treatment, we use an advanced and non-film computerised system known as digital radiography that produces a lower radiation dose compared to the conventional manual X-ray machines.

Some patients suffer from toothache initially that goes away after a course of antibiotics. If the tooth stops hurting, it does not mean that it is not still infected. Root canal is specifically made to disinfect the inner part of the tooth and stop the spread of infection.

Some patients may not experience any kind of pain even with an infected tooth. The root canal infection will usually be found through clinical examination or routine radiographs. Your tooth might still be severely infected.

Apart from performing root canal therapy, the endodontist will examine all clinical and radiographic findings thoroughly in order to as certain if a root canal procedure needs to be performed.

Saving your teeth will always be the main aim of your dental professional. An artificial tooth may impact on your eating certain foods and this would not be the case with a natural tooth. It is important to maintain good dental health and hygiene so that you keep your teeth.

Endodontic treatment is an affordable way to treat infected teeth with a damaged pulp and is usually less costly than tooth extraction and the placing of dental bridge or implant. Endodontic treatment has a greater success rate and the teeth treated through root canal procedure should then last for a long time. The placement of a bridge or dental implant will require more time for treatment and may lead to further procedures being necessary for adjacent teeth and supporting tissues.

The time needed will depend on the details of the procedure you need. The estimated time is usually 1-2 hours, although treatment can often be done in a single visit. At times, you may need a second appointment from the endodontist.

Once your root canal treatment has been completed, the dentist will assess the treatment report. For this, you needed to protect your tooth, which is typically a full or partial crown. Your dentist will then decide on the type of restoration is needed to protect your tooth.
