Patient Information

Endodontics is a branch of dentistry recognized by the Canadian Dental Association involving treatment of the pulp (root canal) and surrounding tissues of the tooth. When you look at your tooth in the mirror, what you see is the crown. The rest of the tooth, the portion hidden beneath the gum line, is called the root. Through the outer portion of the root is a hard tissue called dentin, the inside channel or “root canal” contains a pulp of soft tissue, blood vessels and nerves. Bacteria that are introduced into the pulp as a result of tooth decay, periodontal disease, tooth fracture or other problems, can severely damage the pulp. When that happens, an endodontic specialist removes the diseased pulp to save the tooth and prevent further infection and inflammation. After successful endodontic therapy, the tooth continues to perform normally.

Endodontic treatment is necessary when the pulp becomes inflamed or infected. The most common reasons for inflammation or infection are deep cavities (caries), repeated dental procedures, cracks or chips. Trauma can also cause inflammation and often shows up as discoloration of the tooth. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess.

Indications for treatment include prolonged sensitivity to heat or cold, discoloration of the tooth, swelling or tenderness of the tooth or adjacent gums. Sometimes there are no symptoms.

The Endodontist removes the inflamed or infected pulp, carefully cleans and shapes the canal system and then seals the prepared space. A local anesthetic is administered first.  A sheet of latex called the "rubber dam" (we've got nonlatex ones too) will be placed around the tooth to isolate it, hence keeping it clean and dry during treatment.  The treatment consists of three or four basic steps, but the number of visits will depend on your particular case.  Some treatments take 2 visits but sometimes only a single visit is required.  Occasionally 3 appointments are needed.

Once treatment is completed, you may be instructed to return to your dentist for permanent reconstruction. The restoration of the tooth is an important part of treatment because it seals the cleaned canals from the oral environment, protects the tooth and restores it to function.

There are, of course, no guarantees.  Root canal or endodontic therapy has a very high degree of success, up to 90%.  Teeth which can be treated near ideal have a success rate up to ninety percent!  We will discuss with you the chances of success before any endodontic procedure to help you make an informed decision.  If a root canal or endodontic therapy is unsuccessful or fails you still have options.  

After treatment is completed, even though there is no nerve or blood vessels inside the tooth, it is important to remember that anything that compromises the seal can cause issues with your tooth again.  These can include fractures, caries or failure to properly restore the tooth after endodontic treatment is completed.  

Toothache pain is the main reason for patients seeking treatment. Fortunately, modern anesthetics can make the procedure pain free in most cases. Seeking treatment early makes the procedure more comfortable, so don't wait. When caught early, treatment should feel no different than having a regular filling. For the first few days after treatment, there may be some sensitivity to biting pressure, especially if there was pain or infection before the procedure. Sometimes over-the-counter anti-inflammatory medications (like Advil) are recommended for a day or two. 

No. While radiographs will be necessary during your endodontic treatment, we use an advanced non-film computerized system, called digital radiography, that produces radiation levels up to 90 percent lower than those of already low dose conventional dental x-ray machinery. These digital images can be optimized, archived, printed and sent to other dental professionals electronically.
