One of the most effective techniques for saving decayed or injured teeth is the root canal treatment. Yet when many people hear they need it, they become nervous at the prospect.
Much of this stems from a common misunderstanding that undergoing a root canal is painful. It’s not — today’s anesthetics are quite effective in numbing pain during a procedure, and mild pain relievers like ibuprofen are usually sufficient to manage any discomfort afterwards.
In fact, a root canal treatment relieves pain caused by decay within a tooth. As decay progresses, it can enter the interior known as the pulp, which contains bundles of nerves and blood vessels. It attacks these nerves causing pain and infection. If the infection progresses through passageways known as root canals that are in the roots of the tooth, the pain can intensify. More important, the tooth is in danger of loss as the root and connective tissues that hold the tooth in place are injured from the spreading infection.
During a root canal treatment, we access the pulp by drilling a small access hole, usually in the biting surface or in the rear of a front tooth. Once we enter the pulp chamber we remove all the contaminated tissue. Once thoroughly cleansed, we fill the empty chamber and canals with a special filling (usually gutta percha) to prevent future infection. The access hole is then sealed and at a subsequent visit we strongly recommend placing a permanent crown to provide further protection from damage to the tooth.
Root canal treatments are quite common. All general dentists have been trained in endodontic treatment and can perform most types of procedures. More difficult cases (like a complex root canal network that may be hard to access) may require the services of an endodontist, a specialist in root canals. Endodontists use advanced techniques and specialized microscopic equipment to treat complicated situations.
It’s actually good news if we recommend you undergo a root canal treatment — it means your tooth has a good chance of survival once it’s disinfected and the decay is removed. But don’t delay: the sooner we can treat your tooth, the better your chances of a healthy outcome.

While some people associate the need for root canal treatment with an injury or trauma to a tooth (which is a valid cause), it can also most commonly be caused by tooth decay that is left untreated. This is the reason why we have put together this brief guide to explain the three common stages of tooth decay that lead up to the need for a root canal.
Stage 1: During this stage, decay begins to form in the tiny grooves on the biting surface of a tooth or where the teeth contact each other. The result is loss of the surface enamel of the tooth.
Stage 2: Left untreated, the disease progresses through the enamel and into the dentin, which forms the body of the tooth. Once in the dentin, it progresses more rapidly until it reaches the pulp — the living tissue within the root canals of the tooth. The decay infects the pulp tissues, which contain the nerves of the teeth, causing pain. The end result of inflammation and infection of the pulp is that it dies.
Stage 3: As the nerve dies an infection results, which causes pain and swelling. For some people who do not regularly visit our office, this may be the first physical sign that they have a problem. But all is not lost, a successful root canal treatment, whereby the infected pulpal tissue is removed and the root canals are cleaned and sealed will not only relieve the pain, but save your tooth. So the good news is that once a tooth has had the appropriate endodontic treatment (“endo” – inside; “dont” – tooth) followed by a proper restoration, the tooth can last as long as your other teeth. The key is to take proper care of your teeth, have routine cleanings, and visit our office as soon as you feel you have a problem with a tooth.

When a permanent tooth has been injured, our first priority should be to save it. A root canal treatment (where the interior pulp of the tooth is removed and the pulp chamber and root canals are filled and sealed) is usually the best approach for tooth preservation.
An immature permanent tooth, however, presents a different challenge. While the pulp is less essential to a mature tooth’s vitality, it serves a critical purpose in the tooth’s early development before early adulthood. The pulp produces layers of dentin necessary for the tooth’s root system development. Completely removing the pulp at this stage may retard root development and cause the tooth to eventually weaken, and become brittle and darkened.
For younger teeth, we should therefore use alternative techniques that preserve as much healthy pulp as possible. One of these alternatives is Indirect Pulp Therapy, used when the pulp hasn’t been exposed by the trauma. With this technique we remove as much damaged dentin as possible while preserving the harder dentin closer to the pulp. After applying an antibacterial agent to protect against infection, and then filling and sealing the tooth, the pulp can continue to produce dentin in a normal way.
If pulp exposure has occurred, some form of pulpotomy — the partial removal of any damaged or infected pulp — would be in order. Our goal here is to leave as much of the pulp as possible, and then apply substances that stimulate the remaining pulp to create dentin. The most common type of growth substances are calcium hydroxide or mineral trioxide aggregate (MTA).
If the pulp isn’t at all salvageable, we may then turn to a procedure known as apexification. After removing the pulp we insert MTA at the root end of the tooth, then fill and seal the remaining interior as in a regular root canal treatment. The MTA will help the surrounding bone to heal and continue to grow around the root to further support the tooth.
Recent research into pulp stem cells promises further advances in this area. The regenerative qualities of stem cells could eventually help us “engineer” root development. Until then, there are still effective ways to give a young, damaged tooth a fighting chance to survive.
