Root Canal Treatment

Root canal treatment is an often straightforward procedure to relieve dental pain and save your teeth. Patients typically need a root canal when there is inflammation or infection in the roots of a tooth. During root canal treatment, an endodontist who specializes in such treatment carefully removes the pulp inside the tooth, cleans, disinfects and shapes the root canals, and places a filling to seal the space.

What is a root canal?

 “Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth. Root canal treatment is one type of endodontic treatment.

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. 

How to know if you need a root canal?

Endodontic treatment is necessary when the pulp, the soft tissue inside the root canal, 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, an injury 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.

What are the signs of needing a root canal?

There are a few symptoms that mean you might need a root canal—

• Severe pain while chewing or biting

• Pimples on the gums

• A chipped or cracked tooth

• Lingering sensitivity to hot or cold, even after the sensation has been removed

• Swollen or tender gums

• Deep decay or darkening of the gums

How does endodontic treatment save the tooth?

The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the root canal, then fills and seals the space. Afterward, 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.

Step-by-Step Endodontic Procedure

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

1. The endodontist examines and takes a radiograph of the tooth using x-rays, 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 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 dentist or endodontist may place a post inside the tooth. Ask your dentist or endodontist for more details about the specific restoration planned for your tooth.
