Conventional Root Canal Treatment | Endodontic Treatment Mississauga

What is Endodontic Treatment?

"Endo" is the Greek word for "inside" and "odont" is Greek for "tooth." Endodontic treatment treats the inside of the tooth.

To understand endodontic treatment, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and creates the surrounding hard tissues of the tooth during development.

The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root. The pulp is important during a tooth's growth and development. However, once a tooth is fully mature, it can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.

Why Would I Need an Endodontic Procedure?

Endodontic treatment is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, or a crack or chip in the tooth. In addition, a blow to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess.

Signs of pulp damage include pain, prolonged sensitivity to heat or cold, discoloration of the tooth, and swelling and tenderness in the nearby gums. Sometimes, there are no symptoms.

How Does Endodontic Treatment Save the Tooth?

The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the tooth, then fills and seals the space. Afterwards, you will return to your dentist, who will place a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth continues to function like any other tooth.

Will I Feel Pain During or After the Procedure?

Many root canal procedures are performed to relieve the pain of toothaches caused by pulp inflammation or infection. With modern techniques and anesthetics, most patients report that they are comfortable during the procedure.

For the first few days after treatment, your tooth may feel tender, especially if there was pain or infection before the procedure. The discomfort can be relieved with over-the-counter or prescription medications.

Your tooth may continue to feel slightly different from your other teeth for some time after your root canal treatment is completed. However, if you have severe pain or pressure, or pain that lasts more than a few days, call us immediately.

Endodontic Procedure

Endodontic treatment can often be performed in one or two visits and involves the following steps:

  1. The endodontist examines and x-rays the tooth, then administers local anesthetic. After the tooth is numb, the endodontist places a small protective sheet called a "dental dam" over the area to isolate the tooth and keep it clean and free of saliva during the procedure.
  2. The endodontist makes an opening in the crown of the tooth. Very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling.
  3. After the space is cleaned and shaped, the endodontist fills the root canals with a biocompatible material, usually a rubber-like material called "gutta-percha." The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The temporary filling will be removed by your dentist before the tooth is restored.
  4. After the final visit with your endodontist, you must return to your dentist to have a crown or other restoration placed on the tooth to protect and restore it to full function.

If the tooth lacks sufficient structure to hold the restoration in place, your endodontist may place a post inside the tooth.

Will the Tooth Need Any Special Care or Additional Treatment?

You should not chew or bite on the treated tooth until you have had it restored. The unrestored tooth is susceptible to fracture, so you should see your dentist for a full restoration as soon as possible. Otherwise, you need to only practice good oral hygiene, including brushing, flossing, and regular checkups and cleanings.

Most endodontically treated teeth last as long as other natural teeth. In a few cases, a tooth that has undergone root canal treatment fails to heal or the pain continues. Occasionally, the tooth may become painful or diseased months or even years after successful treatment. Often when this happens, another endodontic procedure can save the tooth.
