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.
Now that celebrities can communicate directly with their fans through social media, we’ve started to see dispatches from some surprising locations — the dental chair, for example! Take singer Kelly Clarkson, who was the first winner of American Idol, and perhaps one of the first to seek moral support via social media before having an emergency root canal procedure.
“Emergency root canal — I’ve had better days,” Kelly posted on her Facebook page, along with a photo of herself looking… well, pretty nervous. But is a root canal procedure really something to be scared about? It’s time to clear up some misconceptions about this very common dental procedure.
First of all, root canal treatment is done to save a tooth that might otherwise be lost to an infection deep inside it. So while it’s often looked upon with apprehension, it’s a very positive step to take if you want to keep your teeth as long as possible. Secondly, tooth infections can be painful — but it’s the root canal procedure that stops the pain. What, actually, is done during this tooth-saving treatment?
First, a local anesthetic is administered to keep you from feeling any pain. Then, a small opening is made through the chewing surface of the infected tooth, giving access to the central space inside, which is called the “pulp chamber.” A set of tiny instruments is used to remove the diseased pulp (nerve) tissue in the chamber, and to clean out the root canals: branching tunnel-like spaces that run from the pulp chamber through the root (or roots) of the tooth. The cleared canals are then filled and sealed.
At a later appointment, we will give you a more permanent filling or, more likely, a crown, to restore your tooth’s full function and protect it from further injury. A tooth that has had a root canal followed by a proper restoration can last as long as any other natural tooth — a very long time indeed.

Everyone's heard the jokes about root canals. Now, let's go beyond the myths and get to the “root” of the matter. Here are a few things everyone should know about this relatively painless and beneficial procedure.
1) If you experience discomfort after eating hot or cold foods, sharp pain when biting down, swelling of the gum tissue, or acute tooth pain, you may need root canal treatment.
All of the above are symptoms of disease in the pulp tissue, which lies deep within the roots of teeth, inside tiny canals that go from one end of the root to the other. Pulp tissue can become infected or inflamed for a variety of reasons, such as trauma or deep tooth decay, causing pain and leading to further complications.
2) Diseased pulp tissue in the root canal must be removed to prevent more problems.
The acute pain may go away — but without treatment, the infection in the pulp tissue won't. It will eventually travel through the ends of the tooth's roots and into surrounding areas. This can lead to dental abscesses, and may even cause systemic problems and diseases in other parts of the body.
3) Root canal treatment is effective.
Removing the diseased pulp tissue removes the infection. Pulp tissue itself is a remnant of tooth development which the tooth no longer needs. After the tissue is removed, the root canal is filled with a biocompatible material, and then it is sealed. A crown or other restoration is usually done after root canal treatment to restore the tooth to its full function.
4) Root canal treatment is generally pain-free.
Just like having an ordinary filling, the process begins with an anesthetic administered to numb the tooth and the nearby area. A tiny hole in the tooth's biting surface provides access to the canal, and minute instruments are used for the procedure. Afterwards, over-the-counter pain relievers are typically all that's needed to relieve the sensitivity that may persist for a day or two following the treatment.
5) A properly done root canal preserves your natural teeth.
A tooth that has had appropriate root canal treatment and restoration can last just as long as a natural tooth. That's important, because the other option — removal of the tooth — can lead to issues like unwanted tooth movement and bite problems. Saving your natural teeth should be the first priority in proper dental care.
