Calgary Root Canal Treatment

Relieve the pain, save your tooth

A root canal can sound intimidating, but its purpose is simple: to relieve pain and save a natural tooth that is infected or badly inflamed. At Rideau Dental on 4th Street, Dr. Janet Kan provides root canal treatment in Calgary and explains what to expect at every step, so there are no surprises.

When is a root canal needed?

Inside every tooth is soft tissue called the pulp, which contains nerves and blood vessels. Deep decay, a crack, a large or repeated filling, or an injury can let bacteria reach the pulp. Once it is inflamed or infected, it cannot heal on its own.

Signs you may need treatment include:

  • A persistent toothache, especially one that throbs or wakes you at night
  • Lingering sensitivity to hot or cold
  • Pain when biting or chewing on one tooth
  • Swelling or tenderness in the gums, or a pimple-like bump on the gum
  • A tooth that has darkened after an injury

Some infected teeth cause no pain at all and are found on an X-ray during a routine exam. That is one more reason regular check-ups matter.

Why a root canal is worth it

    Relieves Pain

    Removing the inflamed or infected pulp usually relieves the pain that brought you in, and stops the infection from spreading.

    Saves Your Natural Tooth

    Root canal treatment lets you keep your own tooth rather than lose it, so you avoid a gap and the cost of replacing it.

    Protects Your Bite

    Keeping the tooth helps your neighbouring teeth stay in position, so you can keep chewing comfortably for years.

    Front teeth, premolars and molars

    Dr. Kan provides root canal treatment in our office for front teeth and premolars. Molars have more canals and a more complex anatomy, so molar root canals are usually referred to a root canal specialist (endodontist). If you need a referral, we will explain why, help arrange it and look after restoring the tooth here once treatment is complete.

    After treatment, it is normal for the tooth to feel tender for a few days. Over-the-counter pain relief is usually enough. Avoid chewing hard foods on the tooth until it is fully restored, and keep brushing and flossing as usual. A well-restored root canal tooth can last for many years.

    How It Works

    1.

    Diagnosis and Freezing

    Dr. Kan examines the tooth and takes an X-ray to confirm the problem. The area is then fully numbed, so most patients feel pressure, not pain.

    2.

    Cleaning and Sealing

    The infected or inflamed pulp is removed, the canals are cleaned and disinfected, then filled and sealed to keep bacteria out.

    3.

    Restoring the Tooth

    A filling closes the tooth. Depending on how much tooth structure remains, a dental crown may be recommended to protect it.

    Frequently asked questions about root canal treatment in Calgary

    Does a root canal hurt?

    The treatment is done with the tooth fully frozen, and many patients say it feels similar to having a filling. In most cases a root canal relieves the pain that brought you in.

    How many visits will I need?

    Many root canals are completed in one or two visits, followed by the final filling or crown. Dr. Kan will give you a clear plan before you start.

    Is it better to just pull the tooth?

    Keeping your natural tooth is usually the better long-term option. An extraction leaves a gap that can affect your bite and neighbouring teeth, and replacing a missing tooth often costs more than saving it.

    Will I need a crown after a root canal?

    Often, especially for back teeth or teeth with large fillings, because a crown protects the tooth from fracture. Dr. Kan will let you know what your tooth needs.

    Do you treat molars?

    Dr. Kan treats front teeth and premolars in our office. Molar root canals are usually referred to an endodontist, and we restore the tooth here afterwards.
