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.
If there was an “Unsung Hero” award for dental procedures, the root canal treatment would win hands-down. Much aligned in popular culture, today’s root canal treatment is actually a valuable tool for saving teeth that would otherwise be lost. And contrary to popular belief, root canal treatments don’t cause pain — they relieve it.
To help you understand its true worth, here are some common questions and answers about the root canal treatment.
What problem does a root canal treatment fix?
A root canal treatment stops a bacterial infection that has invaded the innermost part of a tooth — the pulp — and is advancing toward the end of the root through small passageways known as root canals. Most people first notice the problem as a sharp pain in the affected tooth that may suddenly dissipate in a few days. The infection has attacked the inner pulp tissue, rich in nerve fibers; when the nerve fibers die they stop sending pain signals. The infection, however, hasn’t died: as it advances, you may then begin to experience pain when you bite down or when you encounter hot foods. You may also notice tenderness and swelling in nearby gums.
How does the procedure stop the infection?
A root canal treatment removes all the infected or dead tissue and cleanses the pulp chamber. We enter the pulp chamber through a small access hole created in the tooth’s biting surface. After tissue removal, we then “shape” and prepare the empty chamber and root canals (often with the aid of microscopic equipment) to be filled with a special filling. After filling, the tooth is then sealed to prevent re-infection (most often, we need to install a permanent crown at a subsequent visit for maximum protection).
How much pain can I expect during and after the procedure?
During the procedure, none — the tooth and surrounding gums are fully anesthetized before we begin the procedure. Afterward, you may experience mild discomfort for a few days that can be relieved with over-the-counter medications like aspirin or ibuprofen.
What’s the ultimate value for a root canal treatment?
The procedure can save a tooth severely damaged by the infection. Even covered by an artificial crown, a living tooth continuing to exist and function normally within the mouth is usually more conducive for optimum oral health than an artificial tooth replacement.

Tooth decay can be relentless: left untreated it can work its way into a tooth’s inner core — the pulp chamber or better known as the root canal. Once this occurs, the best course of action to save the tooth may be a root canal treatment to clean out the diseased pulp (nerve) and seal the canal from further decay.
So, what signs and symptoms might you encounter if decay has invaded a tooth’s root canal? When the pulp is first infected you may experience acute pain; over time, however, the pain may suddenly dissipate. This doesn’t mean the tooth has healed itself — quite the contrary, it may mean the infected pulp tissue, including the nerves, has died. Once the nerves die, they no longer transmit pain signals to the brain.
While the pain may cease, the infection hasn’t and will continue to travel from the end of the tooth root into the bone. At this point, you may encounter pain whenever you bite on the tooth. This time the pain is originating in nerves located in the periodontal ligament that surrounds the tooth root and joins the tooth with the jawbone. This can lead to an acute abscess (with accompanying pain) or a chronic abscess that may have no pain symptoms at all. As the decay progresses you may eventually suffer bone and tooth loss.
The important point here is that you may or may not notice all the signs and symptoms that indicate deep decay within a tooth. That’s why it’s important to undergo a thorough dental examination if you have any symptoms at all, especially acute pain that “mysteriously” disappears.
A root canal treatment and removal of the decayed tooth structure will stop the progress of tooth decay and preserve the tooth. The longer you delay, though, the greater the risk your tooth will eventually lose the battle with tooth decay and infection will continue to spread.
