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.

If you regularly participate in sports or other physical activity, you’re at a higher risk for dental injuries. While chipped teeth are the most common result of these injuries, a few may result in more serious trauma — dislodged, cracked or knocked out teeth. In these cases, the core of the tooth — the pulp — and the root may have been damaged. Saving the tooth may require endodontic treatment and possibly the expertise of a specialist in the field, an endodontist.
Endodontics, from the Greek words for “within” and “tooth,” is a specialty of dentistry that treats disease or damage affecting the inner parts of a tooth, particularly the pulp chamber, the root canals, and the root. While all dentists are trained in endodontic procedures, an endodontist has advanced training, experience and specialized equipment to address complex cases.
The type of endodontic treatment needed for an injured tooth will depend on the extent of damage. A mature, permanent tooth with pulp damage, for example, may require a root canal treatment. In this procedure the pulp chamber and root canals are thoroughly cleaned out, and then are filled with a special filling to prevent any future infection. Later the tooth should be crowned to permanently seal it. Although a general dentist may perform a root canal, more complex cases, such as a tooth with an extensive root canal network, may need to be performed by an endodontist using microscopic equipment.
A tooth that has undergone severe trauma, especially a knocked out tooth, will need extensive follow-up care by a general dentist and possibly an endodontist to improve its chances of long-term survival. Because of the severity, the tooth may lose viability and the body ultimately may begin to reject it. For this reason, the tooth should be monitored on a regular basis and may need further treatment from time to time, even up to five years after the injury.
One final word: if you participate in sports or exercise activity, you can significantly reduce your risk of dental injury with a mouthguard. There are various types, but the best protection is one custom designed to fit the specific contours of your mouth. We’ll be glad to advise you further on how to protect your teeth from injury.

As a new permanent tooth develops, the roots undergo a process of breakdown and growth. As older cells dissolve (a process called resorption), they’re replaced by newer cells laid down (deposition) as the jaw develops. Once the jaw development ends in early adulthood, root resorption normally stops. It’s a concern, then, if it continues.
Abnormal root resorption most often begins outside of the tooth and works its way in, beginning usually around the neck-like (or cervical) region of the tooth. Also known as external cervical resorption (ECR), the condition usually shows first as pink spots where the enamel is being undermined. As these spots continue to erode, they develop into cavity-like areas.
While its causes haven’t been fully confirmed, ECR has been linked to excessive pressure on teeth during orthodontic treatment, periodontal ligament trauma, teeth-grinding or other excessive force habits, and bleaching techniques performed inside a tooth. Fortunately, ECR is a rare occurrence, and most people who’ve had these problems won’t experience it.
When it does occur, though, it must be treated as quickly as possible because the damage can progress swiftly. Treatment depends on the size and location of the resorption: a small site can often be treated by surgically accessing the tooth through the gum tissue and removing the offending tissue cells. This is often followed with tooth-colored dental material that’s bonded to the tooth to replace lost structure.
A root canal treatment may be necessary if the damage has extended to the pulp, the tooth’s interior. However, there’s a point where the resorption becomes too extensive to save the tooth. In these cases, it may be necessary to remove the tooth and replace it with a dental implant or similar tooth restoration.
In its early stages, ECR may be difficult to detect, and even in cases where it’s been diagnosed more advanced diagnostics like a CBCT scanner may be needed to gauge the extent of damage. In any case, it’s important that you have your teeth examined on a regular basis, at least twice a year. In the rare chance you’ve developed ECR, the quicker it’s found and treatment begun, the better your chances of preserving the tooth.
Tooth preservation is the ultimate aim of a root canal treatment. But how long should you expect a treated tooth to last? The answer will depend on a few different variables.
A root canal treatment is necessary when a tooth’s pulp — the inner tissue made of nerves, blood vessels and connective tissues — becomes infected with disease. As the pulp dies, the infection spreads into the adjacent bone; this can eventually lead to loss of the tooth.
To stop this process, we enter the tooth and remove all of the pulp, disinfect the pulp chamber and the root canals, and then fill the chamber and canals. Depending on the type of tooth and level of decay, we seal the tooth with a filling or install a crown to prevent re-infection. it’s then quite possible for a treated tooth to survive for years, decades, or even a lifetime.
There are a number of factors, though, that may affect its actual longevity. A primary one depends on how early in the disease you receive the root canal treatment. Tooth survival rates are much better if the infection hasn’t spread into the bone. The earlier you’re treated, the better the possible outcome.
Tooth survival also depends on how well and thorough the root canal is performed. It’s imperative to remove diseased tissue and disinfect the interior spaces, followed by filling and sealing. In a related matter, not all teeth are equal in form or function. Front teeth, used primarily for cutting and incurring less chewing force, typically have a single root and are much easier to treat than back teeth. Back teeth, by contrast, have multiple roots and so more root canals to access and treat. A front tooth may not require a crown, but a back tooth invariably will.
These factors, as well as aging (older teeth tend to be more brittle and more susceptible to fracture), all play a role in determining the treated tooth’s survival. But in spite of any negative factors, a root canal treatment is usually the best option for a diseased or damaged tooth. Although there are a number of good options for replacing a lost tooth, you're usually better in the long run if we can preserve your natural tooth for as long as possible.

According to popular culture, a root canal treatment is one of life’s most painful experiences. But popular culture is wrong — this common treatment doesn’t cause pain, it relieves it. Knowing the facts will help alleviate any anxiety you may feel if you’re scheduled to undergo the procedure.
A root canal treatment addresses a serious problem involving the pulp of a tooth that has become infected. The pulp is a system of blood vessels, nerves and connective tissues inside the tooth that helps the tooth maintain its vitality. It also contains a series of minute passageways known as root canals that interconnect with the body’s nervous system.
The pulp may become infected for a number of reasons: tooth decay, gum disease, repetitive dental procedures, or traumatic tooth damage. Once the pulp becomes irreversibly damaged it must be completely removed from the tooth and the root canals filled and sealed in order to save the tooth.
We begin the procedure by numbing the affected tooth and surrounding tissues with local anesthesia and placing a dental dam (a thin sheet of rubber or vinyl) over the area to isolate the tooth and prevent the spread of infection to other oral tissues. We then drill a small hole in the top of the tooth to access the pulp chamber. Using special instruments, we then remove the infected or dead pulp tissue through the access hole and then wash and cleanse the root canals and pulp chamber with antiseptic and antibacterial solutions.
After additional preparation, we fill the root canals and pulp chamber with a filling especially designed for this kind of treatment, usually a rubber-like substance called gutta-percha that easily molds and compresses when heated. We then seal the access hole with a temporary filling (until a permanent crown can be fashioned) to prevent infection from reentering the pulp space. After the procedure, you may experience some minor discomfort easily managed with over-the-counter pain relievers.
You’ll find the root canal treatment alleviates the symptoms prompted by the pulp infection, particularly acute pain. What’s more, a successful root canal will have achieved something even more crucial to your health — it will give your tooth a second chance at survival.
