Root Canal Therapy Can Relieve the Painful Symptoms & Prevent Extraction

Do I Really Need A Root Canal?

Once a Tooth Root Is Inflamed or Abscessed a Properly Performed Root Canal Procedure May Save Your Tooth.

Root canal therapy, or endodontic therapy, involves the removal of the nerve and blood vessels that are located in the pulp chamber and canal space of the tooth. The chamber and canal space is then cleaned, filled with a filling material  and sealed off to protect the tooth from further infection.


Most root canal teeth require a crown for strength and protection. Some severely broken down teeth may require a post or crown lengthening to properly restore.

Reasons for a Root Canal

Inflammation or Infection of the pulp chamber

  • Cavity extending into the pulp chamber
  • Necrotic pulp – tooth is no longer responsive to hot or cold; the nerve of the tooth is no longer vital (alive)
  • Fractures extending into pulp chamber
  • Trauma caused to a tooth
  • Symptoms
    • Prolonged sensitivity/pain to cold or hot
    • Spontaneous pain
    • Throbbing pain
    • Aching pain
    • Some teeth needing a root canal may be symptom free

Periapical Abscess, Cyst and Granuloma – Infection at apex (tip) of roots

  • Symptoms
    • Swellings or drainage near tooth in question
    • Sensitivity/pain while chewing or biting
    • Dull/Aching pain
    • Tenderness to touch to surrounding bone or tissues
    • Some teeth needing a root canal may be symptom free


  • After a deep filling and the tooth remains sensitive
  • After placement of a crown and the tooth remains sensitive
  • Following Orthodontic tooth movement
  • Elective Root Canal for Cosmetic reasons due to misaligned or a crooked tooth that needs to be realigned into correct position

What Happens If I Don’t Get Treated?

  • Extraction
  • Infection to adjacent teeth resulting in Root Canal Therapy of several teeth or extraction of several teeth
  • Infection to sinuses or the lower jaw that may result in loss of a portion of the jaw or can lead to obstruction of respiratory structures which can be life threatening

Frequently Asked Questions

What is root canal therapy?

It is the removal of pulpal tissue from the tooth in an attempt to cure an existing infection, cyst or granuloma. Studies indicate that root canal treatment is 90 to 95% successful. Furthermore, because the procedure is a restorative one, the cost is often covered by insurance. 

How many appointments will it take?

Usually one or two appointments depending on the situation. A third, short appointment is necessary if you are having a crown after the root canal.

Will I have pain after my procedure?

It is not uncommon for you to experience an uncomfortable or dull ache after your root canal. Sensitivity upon biting is also common. These symptoms can last up to a week.

If I’ve had the nerve removed from my tooth, why is it possible that it could hurt after a procedure?

Sometimes the infection in your tooth spreads to tissues under the roots of your tooth and can cause pain. This will heal once the canals of your tooth are cleansed of the infection.

Will I have swelling afterwards, if so what should I expect?

In some cases swelling will occur in the area. If this occurs, please call us to let us know. Antibiotic therapy may be necessary. The swelling will usually subside in 2-3 days. Occasionally, a small “bubble” or pimple will appear on the gum tissue beside the tooth. This is a release of pressure and bacteria from around the tooth and should go away within a week.

What about medications following a procedure?

Depending on your case, pain medication and/or antibiotics will be prescribed. Please take them only as directed.

Why do I need a crown after a root canal?

Doing a root canal weakens the tooth. A crown is needed to maintain the strength of the tooth. Please chew on the other side from your root canal. Avoid sticky, chewy or crunchy foods to prevent cracking the tooth or your temporary. If any problems arise, feel free to call the office.
