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.

Which would you rather have — the flu or a root canal procedure? Nearly 80 percent of people recently surveyed by the American Association of Endodontists wisely chose the root canal. If this takes you by surprise, then let us bring you up to date on root canal treatment today. It’s nothing like the experience that once made it the butt of jokes and a benchmark against which other “undesirable” experiences were measured.
The term “root canal” actually has two meanings. It is part of the pulp-filled chamber at the center of every tooth containing nerves and blood vessels that keeps teeth vital (alive). It’s also the endodontic (endoÂ = inside; dont = tooth) procedure that treats inflammation and infection in this tissue. Common causes of pulp problems are traumatic damage (for example a crack, chip, or root fracture), deep decay, or gum disease.
The first sign of a problem is typically pain — ranging from acute and intense pangs when biting down, to lingering discomfort after consuming hot or cold foods, to a chronic dull ache and pressure, or tenderness and swelling in nearby gums. The primary pain may abate as the nerves in the pulp die, but the infection will continue, compromising the affected tooth, jeopardizing the health of the surrounding tissues, and often triggering secondary pain.
Pain-Relieving, Tooth-Saving Treatment
Endodontic treatment, by contrast, is no more uncomfortable than having a cavity filled. The tooth and surrounding area are numbed with a local anesthetic before the procedure begins. In order to access the diseased pulp, a small opening is made in the biting surface of the tooth. Tiny instruments are used to remove the pulp, clean and disinfect the root canal(s) and pulp chamber, and prepare the empty tooth interior to receive a biocompatible filling material to prevent bacteria from returning. A permanent crown may be placed over the tooth at that time, or a second visit may be needed. A crown (cap) is important to the tooth's long-term strength and functionality.
For a day or two following treatment you may experience temporary sensitivity, which often responds to an over-the-counter medication like ibuprofen. Occasionally, prescription medications, including antibiotics, may be needed.
All in all, doesn’t saving a tooth sound easier and more constructive than coming down with the flu?

If a pain you’ve been feeling goes away, you might believe the problem that caused it is gone too. But that doesn’t mean it has, especially with a tooth. An excruciating toothache that suddenly stops should still be examined. Here’s why.
Tooth decay often works its way into a tooth’s innermost layer, the pulp, which contains bundles of nerves and other tissue. The infection attacks the nerves, which send pain signals to the brain. As the infection persists, though, the nerves will eventually die and will no longer be capable of sending pain signals — hence the “mysterious” end of your toothache.
Although the pain has stopped, the infection is very much active in the tooth and will continue to work its way through the root canals to the jaw. And ultimately, the pain will return as the infection invades the bone.
But there’s good news: a tooth in this condition can be saved with a procedure known as root canal therapy. We drill a small hole in the tooth to access the pulp, usually through the biting surface of back teeth or in the rear in front teeth. Once inside the pulp chamber, we clean out the infected and dead tissue. We then fill the empty pulp chamber and the root canals with a special filling and seal the access hole. In a few weeks the tooth receives a life-like crown to further protect it from re-infection and fracture years later.
A straightforward root canal treatment can be performed by a general dentist. If there are complications like a complex root canal network, however, then the skills and specialized equipment of an endodontist (a specialist in root canals) may be needed.
A root canal treatment resolves the real cause of a toothache that suddenly stopped, as well as puts an end to future pain and infection related to the tooth. More importantly, it can save your tooth and add many more years to its life.
