Latest Technology in Root Canal Treatment

Underneath each tooth's outer enamel is an area of soft tissue called the pulp, which carries the tooth's nerves, veins, and arteries. Root canals are very small, thin passageways that branch off from the top pulp chamber through the root tip. A tooth can have up to four root canals.

Sometimes, the pulp inside the tooth becomes infected by disease or bacteria, or damaged by a traumatic injury to the tooth. An infected and untreated root canal can allow bacteria in the mouth to enter the bloodstream and cause infections in other parts of the body. In addition to staving off potentially harmful infections in other parts of your body, root canal treatment can generally save your damaged tooth.

Root canal treatments typically affect the root tip or nerve of the tooth and the structures called the pulp chamber, pulp, and root canal. The procedure involves removal of diseased or damaged pulp inside the tooth, the cleaning, disinfection and reshaping of the inner canals beneath the tooth, and preparation of the tooth for later placement of a filling, and in most cases, an artificial crown made of porcelain or gold. The procedure enables you to keep most of your original tooth.

Root canal treatment usually takes one to three visits. Here is what normally occurs during a root canal procedure:

  • First, your gums are numbed with a topical substance and a local anesthetic is injected into the nearby area to completely numb your teeth, gums, tongue, and skin. For patients with an acute low tolerance for pain or anxiety, nitrous oxide gas may be used.
  • A small sheet of rubber is placed over the surrounding area of the affected tooth in order to isolate it from surrounding teeth and prevent you from swallowing debris.
  • A small hole is made in the top of the tooth in order to access the pulp chamber, pulp and root canals. The pulp is removed, the pulp chamber cleaned and the canals are cleared of debris and tissue. In most cases, the canals are first filled with antibiotic medications and temporary filling materials up to the gum line. Depending on the circumstances, the root canal may be left open for a few days in order to drain. In some cases, the canals may be filled right away with a final root canal filling.
  • If the canals are not permanently sealed, the temporary filling is removed and the pulp chamber and canal(s) are filled with a rubber-like material to prevent recontamination. If the tooth is still weak, a metal post may be inserted above the canal filling to reinforce the tooth.
  • Once filled, the area is permanently sealed, an impression of the tooth is made so an artificial crown can be made for placement over the affected tooth. In some cases, a temporary crown is placed over the tooth until the permanent gold or porcelain crown is made and cemented in, usually by your family dentist.

    Reasons for root canal treatment
    Root canal treatment is called for when the soft tissue inside the tooth's canals, also called the pulp, becomes inflamed or infected by bacteria. The most common cause of pulp death is a fractured tooth or a deep cavity, which can expose the pulp to the bacteria found in your saliva. A traumatic injury or blow to the tooth could cause swelling and inflammation of the tissues in and around the tooth, providing an opportunistic path, usually through a crack, for bacteria to collect. Repeated dental procedures on the same tooth could eventually weaken and compromise the original tooth, allowing pathogens to enter the inner canals. An infected pulp can lead to swelling and possibly fever; left untreated, infected pulp could leak harmful toxins from the root ends, leading to an abscess and erosion of the bone beneath the tooth.
    Post-treatment care
    A root canal procedure is designed to restore a damaged inner tooth, giving it the same lifespan as its original. With proper care following your procedure, your restored tooth should heal with about a 95% success rate. It is normal to feel some tenderness in the area over the next few days as your body undergoes the natural healing process. You may also feel some tenderness in your jaw from keeping it open for an extended period of time. These symptoms are temporary and usually respond very well to over-the-counter pain medications. It is important for you to follow the instructions on how to take these medications. Remember that narcotic medications, if prescribed, may make you drowsy, and at least eight hours should pass prior to operating dangerous machinery or driving a car after taking them. Your tooth may continue to feel slightly different from your other teeth for some time after your root canal treatment has been completed. However, if you have severe pain or pressure that lasts more than a few days, contact our office.

Latest Technology in Root Canal Treatment at Our Offices

3D CBCT Imaging
Three-dimensional Cone Beam Computed Tomography (3D CBCT) imaging provides exceptional information that traditional x-rays can not provide. These types of information are significantly helpful in every step of root canal procedures. CBCT is an exciting new technology that allows endodontists to examine teeth, their root canal space, and the surrounding anatomical structure in 3D. This information allows our endodontists to make early detection of the diseases caused by root canal infection, configure the number and shape of root canals, evaluate the critical anatomical structures such as maxillary sinus and main conduit of nerve and blood vessels. In cases of retreatment of previously treated root canals, the CBCT image provides a thorough analysis of the condition and insights on how to resolve the problem. CBCT Imaging helps our doctors to make a more accurate diagnostic decision, establish improved treatment planning, and enhance their performance during the treatment procedures. All these advantages benefit our patients with the enhanced outcomes of the treatment that our office provides.

Dental Operating Microscope and Micro-Endodontics
Enhanced magnification (3-21x) and Xenon illumination provide an unparalleled view for our endodontists to see tiny details of root canal space inside your tooth. Better visualization of anatomy is critical to improving the quality of the diagnosis and the treatment allowing us to provide care at the highest level possible. Endodontic procedures performed at a microscopic level helps to target the root canal infection with precision and save the tooth structure to increase the longevity of the treated tooth.

The image below shows the endodontic access made in an upper molar through the existing crown by using a dental operating microscope.
Upper Molars usually have three roots - MB, DB, and P. The image shows commonly existing two canals (MB1 and MB2) in the MB (Mesio-Buccal) root of the upper molar.

Digital Dental Radiography
Digital dental radiographs are invaluable aids in diagnosing and treating dental diseases and monitoring dental health. Exposure time for digital radiographs is about 75 percent less when compared to traditional radiographs and this results in a significant reduction of radiation exposure to our patients. The advantages of digital imaging enable us to not only store patient images without taking up physical space but also enables us to efficiently transfer them to appropriate dental providers or insurance companies with protective encrypted measure and better serve our patient care.
