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.

It’s often best health-wise to preserve even the most troubled tooth—including a child’s primary (“baby”) tooth. If that sounds like too much effort for a tooth that lasts only a few years, there’s a big reason why—if it’s lost prematurely, the incoming permanent tooth above it could erupt out of position.
Preserving a decayed primary tooth could include procedures similar to a root canal treatment, commonly used in adult permanent teeth with inner decay. However, we may need to modify this approach to protect the primary tooth’s pulp. This innermost layer plays a critical role in early dental development.
Because an adult tooth has reached maturity, removing diseased pulp tissue has little effect on its permanent health. But the pulp contributes to dentin growth (the layer between it and the outer enamel) in primary and young permanent teeth, so removing it could ultimately compromise the tooth’s long-term health.
Our goal then with a child’s tooth is to remove as much diseased tissue as possible while involving the pulp as little as possible. What techniques we use will depend on how much of the pulp has become infected.
For example, if decay has advanced to but hasn’t yet penetrated the pulp, we may remove all but a small amount of the decayed structure just next to the pulp to avoid its exposure. We may then apply an antibacterial agent to this remaining portion and seal the tooth to curb further infection.
If on the other hand the pulp has become infected, we may try to remove only the infected portion and leave the remaining pulp intact. We’ll only be able to do this, however, if we deem the remaining pulp healthy enough to remain infection-free after the procedure. If not, we may need to remove the entire pulp as with a traditional root canal. This option, though, is a last resort due to the possible effect on dentin growth and the tooth’s long-term health.
As you can see attempts to preserve a primary tooth can be quite involved. But if we can help it reach its full life span, it could mean better dental health for a lifetime.

Root canal treatments are an essential part of dental care — countless teeth with deep decay would be lost each year without it. Now, this traditional dental care procedure is advancing to a new level of precision through lasers.
Root canal treatments have a simple goal: access a tooth's infected pulp and root canals, clean out the infected tissue and fill the empty pulp chamber and canals with a special filling. Once filled, the access is sealed and a porcelain crown later placed for additional protection against re-infection.
In the traditional procedure, we perform these steps manually with a dental drill and hand instruments. We may also need to remove a good portion of tooth structure, both healthy and infected tissue. A laser, on the other hand, is a highly focused beam of light with the ability to interact with healthy and infected tissues differently: destroying infected tissue while having no effect on nearby healthy tissue. The end result: we may be able to remove less healthy tissue with lasers than with the conventional procedure.
Lasers are also helpful with softening and precisely molding the filling material within each canal's particular shape. And, early reports seem to indicate a higher degree of comfort for patients (less drill noise and need for anesthesia), less bleeding and faster recovery times than the conventional approach.
But as a tool for root canal treatments, lasers do have a couple of disadvantages. While light travels in a straight line, root canals are rarely straight — conventional instruments with curved designs usually accommodate odd canal shapes better than a laser. Lasers can also raise temperatures within a tooth that can damage healthy tissue, both within the pulp and outward into the dentin.
Still, lasers for root canal treatments appear promising with some dentists using a combination of lasers and manual techniques to garner benefits from both approaches. While you won't see lasers replacing the traditional root canal treatment anytime soon, the future looks bright for more efficient ways to treat deep tooth decay.
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.
Many people consider a root canal treatment to be potentially an unpleasant experience. You might even feel a few butterflies fluttering in your stomach if we were to recommend one for you.
But there’s nothing actually to dread about this common and very effective treatment. The procedure doesn’t cause pain; in fact, it most likely relieves tooth pain. What’s more, it could save a tooth that would be otherwise lost.
The name comes from narrow passageways extending from the tip of the root to the innermost tooth pulp. The pulp contains nerves and other structures once vital to early tooth development. And although they’re not as important in a fully mature tooth, those nerves still function. In other words, they can still feel stimulation or pain.
That shouldn’t be a problem with a healthy tooth. But if tooth decay invades the inner pulp, those nerves now under attack will begin firing. You’ll know something’s wrong. As bad as it feels, though, the toothache isn’t your worst problem: if the decay isn’t stopped, it can spread through the root canals to the bone that could eventually lead to losing the tooth.
A root canal treatment removes the decayed pulp tissue and protects the tooth from re-infection. We first deaden the tooth and surrounding tissues with a local anesthesia and set up a rubber dam around the tooth to protect it from contamination from the surrounding environment. We then drill a small access hole through the enamel and dentin to reach the pulp chamber and root canals.
Using special instruments, we remove all the diseased tissue from the pulp and flush out the empty chamber and root canals with antibacterial solutions. After re-shaping the root canals, we fill them and the pulp chamber with gutta-percha, a rubber-like biocompatible material that conforms well to the root canal walls. We seal the gutta-percha with adhesive cement and then fill the access hole. Later, we’ll give the tooth further protection with a custom crown.
After the procedure, you may experience short-term minor discomfort usually manageable with over-the-counter pain relievers like ibuprofen. The good news, though, is that the excruciating nerve pain from within the tooth will be gone—and your tooth will have a new lease on life.
