Root Canal Therapy

Root Canal Therapy

 

A root canal procedure (also known as root canal therapy or RCT) is usually the best way to clear infections in a root canal. When dental pulp, the blood vessels and nerves found within a tooth, becomes badly damaged by decay or tooth fracture, irreversible pain and sensitivity may occur, resulting in the need for a restorative procedure like a root canal treatment.

During the root canal procedure, your dentist will clean out the infected root canal and then seal it with inert material to prevent future infections.   

If left untreated, an infected root canal, and subsequent abscessed tooth, can cause one or more of the following:

  • Swelling that could spread to other areas of the face, neck or head causing various complications.

  • Bone loss around the tip of the root

  • Pus drainage that can ooze into the gums and even through the cheek into the skin

Root canal symptoms

The roots of teeth contain blood vessels, nerve fibers and soft lymph tissues. These tissues can become damaged or infected due to various causes, but most commonly a deep cavity. Root canal therapy is often the best option to relieve pain and avoid losing the tooth entirely. You may need a root canal if you experience one or more of the following root canal symptoms.
 

Common symptoms of tooth that may require a root canal therapy.

  • Tooth discoloration due to injury or trauma

  • Swollen and sensitive gums near the sore tooth

  • A strong, sustained throbbing pain in the area of the tooth

  • Pain when chewing on a particular tooth or a certain side of your mouth

  • Pain lasting several hours when consuming cold food or drinks 

In rare cases, no symptoms may be present even if you have a root canal infection, so it is always best to see a dentist every six months and practice good oral hygiene habits.

Root canal procedure

Here are the stages leading to an infected root canal:

Root canals for baby teeth

There’s a common misconception that baby teeth don’t matter. However, baby teeth are crucial for healthy adult teeth to develop, so it’s important to address infected root canals and abscessed teeth before the issues spread and cause further damage to a child’s mouth. There are two types of pediatric root canal procedures: a pulpotomy and a pulpectomy. In a pulpotomy, the coronal part of the pulp is removed while in a pulpectomy procedure, the crown and the root canal of the pulp chamber is removed.

Pulpotomy

A pulpotomy, sometimes referred to as a baby root canal, is a root canal procedure typically used to treat infected baby teeth. Different from a pulpectomy, a pulpotomy restores and saves a tooth that’s infected by a deep cavity. It’s important to treat a deep cavity in a baby tooth to avoid the spreading of inflammation and infection that can cause an abscessed tooth and further issues down the road.

Pulpectomy

A pulpectomy is another root canal procedure performed on baby teeth. Depending on how far the infection of a root canal extends, a Dental Associates pediatric dentist or endodontist may perform a partial root canal. This procedure, called a pulpectomy, will relieve pain and allow time for antibiotics to reduce the infection. At an initial appointment, the endodontist will administer antibiotics to reduce the infection. At a second appointment, the endodontist will remove the infected pulp, and clean and fill the infected canal so the primary tooth can stay in the mouth and ensure proper growth and placement of the incoming secondary (adult) teeth.
 

Root canals for adults

Pulpectomy

A pulpectomy can be performed on an adult tooth as well as a baby tooth. A pulpectomy involves the complete removal of pulp tissue in a tooth as the first step in root canal treatment. This procedure will remove all the infected pulp, both in the crown portion of the tooth and the roots, to preserve as much of the natural tooth as possible.

Apicectomy

An apicoectomy is the root canal procedure typically used to treat an abscessed tooth in adults. They’re performed on teeth that already had a root canal completed but the original root canal was not successful in eliminating the infection. In an apicectomy, a dentist will remove a portion of the root tip as well as the apical infection. Once your dentist removes the infected tissue and cleans the entire area, the canal is filled with a biocompatible material called Gutta Percha, which is a rubber-like material that seals your tooth from bacteria and reinfection. And when necessary a final crown or cap is prepared for the severely damaged teeth.
