Root Canal Therapy

Root canal therapy is also known as endodontic therapy. This is necessary when the innermost layer of the tooth, the pulp, is inflamed or has been infected by bacteria, and is now considered “dead”. When this occurs, a persistent toothache occurs. In order to alleviate the pain and infection, the tooth is disinfected and sealed with a filler. Antibiotics may be required to help alleviate the infection. A dental restoration is then placed on top to help protect the tooth and maintain the tooth integrity. The purpose of root canal therapy is to save teeth.

Causes of Root Canal Therapy

  • Deep dental decay
  • Fractured tooth
  • Broken tooth
  • Dental Trauma or Accident
  • Internal Resorption
  • Multiple dental restorative procedures

Commonly Asked Questions Regarding Root Canal Therapy

How is Root Canal Diagnosed?

A Root Canal is diagnosed with a dental x-ray, dentist examination, and history of symptoms.

What are some signs and symptoms that root canal treatment is needed?
  • The tooth becomes extra sensitive to hot and cold foods
  • Pressure on the tooth causes great pain
  • Frequent tooth and gum pain
  • An extremely large, visible cavity in tooth
  • Abscess with pus draining into the mouth

How is root canal therapy performed?

The tooth is properly numbed with anesthesia. It is then isolated and disinfected. Afterward, a filling material is placed in the canals. The tooth will then be temporarily sealed until the final restoration is placed in the tooth.


How many visits does root canal therapy take?

This is individual for each tooth and situation. Typically root canal therapy can take anywhere from 1 visit to 3 visits to complete. This is dependent upon the number of nerves in the tooth, and how badly the tooth is infected.

Will my tooth be removed during root canal therapy?

No. During root canal therapy, your tooth is not removed. Only the infection is removed.

Does Root Canal Therapy hurt?

If a tooth is properly anesthetized, there should no pain during the procedure. After the procedure is completed, some soreness and some pain may be present. Your dentist will properly inform you after your procedure.

My dentist advised me that I needed root canal therapy when my tooth was painful. The pain has now stopped. Do I still need root canal therapy?

Please be advised that root canal therapy is indicative of an infection of the tooth and should be taken seriously. The infection will go through phases of being active and inactive. During these phases, the infection can be compared to a “hurricane”, which continues to grow in strength. If not properly addressed, one can end up with severe pain, dental abscess, facial swelling, fever, cellulitis, and a trip to the hospital!!

Why is my tooth dark after root canal therapy?

Although not typical, this can occur because the nutrients that were keeping the tooth healthy are no longer in the tooth and have been removed due to infection. After root canal therapy, a crown or veneer is placed over the tooth to mask the color change and to protect the tooth from cracking.

Do I need a crown or veneer placed on my tooth after root canal therapy?

In a most of the cases, yes. After root canal therapy, a tooth is very brittle and is prone to fracture. A crown or veneer will stabilize and protect it from breaking.

I had root canal therapy completed and my tooth does not bother me. Do I need to complete the post and the crown?

Yes. Root canal therapy only removes the infection within the tooth. You will need to restore the tooth with a post and a crown in order to restore the tooth it’s original strength. If the post and crown is not completed, the tooth will fracture and require a dental extraction.

Do I need to take medicine during root canal therapy?

Yes, a patient usually requires antibiotics and pain medicine during the root canal procedure.
