When Is Root Canal Therapy Necessary?

Dentists employ the use of root canal therapy when a tooth nerve has become decayed or infected. To salvage your tooth, your Empress Walk Dental dentist will:

  • Remove the nerves, pulp (the living tissue inside the tooth), bacteria, and any decay from inside the tooth
  • Fill the tooth with specially treated dental materials that contain a medication which will help the tooth heal and function as it should

Why Not Just Pull the Tooth That Hurts?

Some patients erroneously believe that it is better to extract (or pull) a tooth that causes them pain rather than have a root canal treatment. What these patients do not understand is that by saving the tooth via the root canal procedure, we also save them time, money, and further problems with their other teeth that lie near the tooth in question.

Generally, root canal treatments work the first time, and it is rare (though not unheard of) for a tooth to undergo a second root canal later on because of a new infection. Your Empress Walk Dental dentist intends for your root canal treatment to be a lifelong solution for your problems with that particular tooth.

How Do I Know If I Need a Root Canal?

If you are experiencing any of the following symptoms, ask your Empress Walk Dental dentist if you might need root canal therapy:

  • An swelling or pimple on the gums
  • Sensitivity to heat and cold
  • Severe tooth pain/toothaches
  • Swelling and/or tenderness
  • Injury or trauma to a tooth

Sometimes infected teeth have not yet caused the patient any trouble, yet a root canal is still the best course of action to prevent the tooth from decaying any further. The best way to prevent root canals, or to find out if you are a candidate for one, is to make an appointment with your Empress Walk Dental dentist in Toronto or North York so you can be evaluated by a dental health professional

Okay, So I Might Need A Root Canal. Now What?

A root canal procedure necessitates at least one office visit to a dentist or endodontist (root canal specialist), sometimes more depending upon the specific circumstances.

Here is what happens during a root canal procedure:

  • The dentist numbs the tooth
  • A piece of rubber will be put around the tooth to ensure that it stays dry and saliva-free.
  • An access opening is created on top of the tooth, and several root canal files are placed individually into the opening to get rid of the pulp, nerve tissue, and bacteria
  • Any tooth decay will be removed using the appropriate dental instruments
  • The tooth is completely cleaned out and then sealed with either a permanent or temporary filling (if a follow-up appointment is necessary)
  • At a follow-up appointment, which typically takes place after about a week, the roots and the inside cavity of the tooth will be packed and sealed with special dental materials.
  • Then, a filling will be placed to protect the recess on top of the tooth.
  • Finally, all teeth that have been treated with the root canal procedure will have a crown (or cap) placed to make sure that the tooth stays whole and returns to health
    Post-procedure, your tooth may still be sensitive or sore, but these feelings will diminish as the irritation dies down and the tooth improves. After each appointment, your Empress Walk Dental dentist or hygienist will give you detailed care instructions so you receive the maximum benefits from the procedure. These instructions will show you how to improve your oral hygiene to keep your root canal treatment in good shape for as long as possible.
