Root Canal Therapy

The root canal is one of the most common dental procedures performed; more than 14 million performed a year with over a 95% success rate. This simple procedure can save your natural teeth and prevent the need for dental implants and bridges down the road.

A root canal is a specialized treatment used to save teeth that are damaged or diseased due to a deep cavity or traumatic injury to the dental pulp. The pulp is the soft tissue at the center of the tooth which contains the blood vessels, nerves, and connective tissue. If the infected pulp is left untreated, an abscess may form at the end of the root, which can cause severe pain and swelling. The infection can also spread and damage surrounding bone and lead to possible tooth loss.

The procedure involves the removal of the damaged pulp from the root canal system. Once the pulp is removed, the canals are cleaned, disinfected, and sealed.

After a root canal procedure is completed, a crown will usually be required to protect the tooth from fracturing.  You will receive a temporary crown after your root canal.  It is extremely important that you have your permanant crown made and placed within no more than 30 days after your root canal, or you may increase the risk of failure and potentially loose the tooth.

Treatment usually requires one visit and takes from 1 to 2 hours to complete under local anesthesia.  Ask us about Sedation Dentistry.  We do offer Oral Conscious and Nitrous Oxide sedation.  If desired,  a sedation consultation with the dentist is required prior to treatment.

Root Canal Retreatment

Statistically there is about a 5% that a root canal will fail, meaning that the tooth will become re-infected. When this happens the root canal can be re-treated. This procedure entails removing the existing filling in the canals and starting the process over again.

Apical Surgery (Apicoectomy)

If a root canal fails, there are several options available. In many cases, the root canal can be retreated. However, when access to the root apices, or root tips, is not possible using conventional root canal treatment, a procedure called an apicoectomy can be performed. An apicoectomy is the removal of the root tip and surrounding infected tissue of an abscessed tooth.

An incision is made in the gum tissue to expose the bone and inflamed tissue. The infected tissue is removed, along with the end of the root tip. A root-end filling is placed to seal the end of the root and to prevent further infection, and the gum is sutured. The bone heals over the root in a few months, and full function is restored.

The Benefits of Technology - Making Root Canals Easier

Modern innovation in technology has introduced the rotary instrument system into the field of Dentisty.  Rotary Endodontic instruments allow the dentist to perform the root canal 2-3x faster than traditional methods.  The benefit to you is less time and minimal discomfort.
