Root Canal Treatment
A root canal treatment is a dental procedure that is used to remove diseased pulp tissue from the interior of a tooth. The narrow channels beneath the pulp chamber in the inner part of the tooth are hollowed out and cleaned, and the roots are filed with flexible nickel titanium files. Root canal treatment restores and saves an average of 17 million teeth each year. Keep your tooth and stop the pain – sounds better than a tooth extraction, right?
A tooth is made up of three main components: a hard protective shell referred to as enamel, a softer and sensitive middle layer referred to as dentin and a soft tissue inner layer referred to as dental pulp. Dental pulp is composed of nerve tissue, lymph tissue and blood vessels, and is considered to be the vital part of a tooth. If dental pulp is sufficiently traumatized – whether by exposure to oral bacteria via deep dental caries, a fracture in the tooth that enters the pulp or a forceful blow to the face – the tooth begins to die and root canal therapy is often required in order to prevent or eliminate infection and prevent tooth loss.
A root canal procedure involves tooth disinfection and the removal of all debris (nerve tissue, lymph tissue, blood tissue, bacteria and infection) from the coronal pulp chamber and its associated canals. Once an affected tooth's canals are sufficiently cleansed and shaped, they are filled with materials designed to prevent pain and infection from recurring.
Signs of Infection
Certain signs may indicate that you have a diseased tooth or infected nerve and therefore may need a root canal. These signs include:
- Minimal to severe pain.
- Tooth discoloration.
- Swelling and irritation in the surrounding gum tissue.
- Signs of infection visible on a radiograph.
Dentists typically recommend a Root canal treatment in such situations to save the affected tooth and preserve its functionality.
Why Are the Associated Toothaches So Painful?
Nerve fibers, blood, and lymph tissues are housed in the root canals. Located inside each tooth is a pulp chamber that funnels into those canals.
A tooth can become inflamed or infected for several reasons, including severe tooth decay or a crack or chip in the tooth. Failing restorations such as dental fillings and dental crowns can foster bacterial leakage into the dental pulp. Once infected, the dental pulp begins to die and the body's inflammatory responses set it. The combination of infection and inflammation can cause significant pain. The end result is a toothache.
In cases where tooth extraction is the only solution, the missing tooth may be replaced with a dental implant or dental bridge to maintain functionality. By replacing the missing tooth, a proper bite is maintained and the surrounding teeth are prevented from shifting. Because a severe infection can be very dangerous, it is important to receive a professional evaluation by a dentist who can look deeper into the cause of a toothache. If an infection spreads beyond the jaw to the head and neck, then more extensive medical treatment, including hospitalization, may be required.
Root Canal Treatment Procedure
At the first dental visit, you may be prescribed antibiotic treatment for a number of days before the root canal procedure is performed. At the beginning of the procedure, your dentist will anesthetize the tooth sufficiently to prevent pain while performing the procedure.
A drill is then used to access the pulp chamber and associated canals of the tooth. Using flexible nickel titanium pin-like files, the dentist will delicately (but thoroughly) cleanse the length of the canals and tip (or apex) of the root to completely remove all traces of infection or debris. This process is performed with a great deal of care in order to minimize damage or trauma to the surrounding ligaments and bone. To accomplish this, the dentist may use additional tools to measure the root. These tools may include digital X-rays taken during the cleaning phase, an apex locator that works as a sonar probe to locate the tip of the root and a microscope providing up to 32-times magnification.
Your dentist will then disinfect and seal the tooth. Some dentists and endodontists use a special type of heat gun to fill the canal with a material called gutta-percha. Gutta-percha is a natural, biocompatible, anti-bacterial material that expands and seals the hollowed area within the span of about 15 minutes. Other dentists and endodontists may use the bonding process to seal the tooth with a resin material. The dentist then fills the canal's access hole with a temporary or permanent filling.
On occasion, a temporary filling is placed in the hole used to access the root canals in order to allow time for healing. Once the tooth is deemed to be healing properly and the root canal deemed a success, a permanent restoration (such as a dental filling or crown) is placed. During the interim, you may receive medication to manage the soreness and discomfort that may result from the procedure.
How Much Does Treatment Cost?
Root canal treatment cost varies per
- Location of the teeth
- Number of visits - Single Visit RCT costs slightly more than multi visit procedure
- Experience of the dentist whether a general dentist or a specialized endodontist is treating you
Here is a comprehensive cost of the procedure, post a root canal treatment the tooth must be capped with a crown.
Finding the Right Dentist
Simple root canals may be performed by a general or family dentist. However, if the canal has an anatomy complex enough to make it difficult to find, navigate or reach the root may require the touch of an endodontist. Endodontists are specialist dentists who focus on disorders of the dental pulp and specialize in treatments such as root canals. An endodontist also is recommended for teeth with more than one canal, such as molars. Center for Dental Implants & Esthetics always deploys a qualified Endodontist for the procedure.
Today's Root Canal Treatment Advantages
The technology of today's dental instruments has led to revolutionary enhancements in treatment. For example, endodontists and dentists of the past had to feel their way through the anatomy of the tooth in order to locate the tiny canals that house pulp tissue. Today, the use of a microscope allows dentists to easily navigate through even the most complex anatomy.
Ultrasonic needle: In the past, it was extremely difficult to remove broken files from roots, at times resulting in the loss of the tooth being treated. Today, an ultrasonic needle may be used to send a vibration down the canal to a broken file for its removal.
Water Laser: The use of the laser is just starting to crest in endodontics. The endodontist or dentist may disinfect the tooth using a water laser with a bleaching solution. Laser dentistry technology is still developing in this new area, but the use of the water laser holds promise.
Single Visit RCT: It is also known as single visit endodontics is always performed by an Endodontist. This requires a patient to visit only once for root canal treatment procedure. Post treatment visits are required for fixing crown over the treated tooth.
