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.
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.

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 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.

Perhaps you’ve been told that you need to have root canal treatment in order to save one or more of your teeth. By now, you know that the procedure itself is essentially pain-free, and that it has an excellent chance of success. But you may be wondering — just how long can you expect that “saved” tooth to last?
The short answer is: decades… or even a lifetime. But in just the same way that no two fingerprints are exactly identical, neither are any two teeth with root canals. There are some factors that could result in one tooth having a greater longevity after root canal treatment (RCT) than another — but before we go into them, let’s look at what RCT actually involves.
When infection and inflammation is allowed to get a foothold deep inside a tooth — usually due to uncontrolled decay or trauma — the nerves, blood vessels and connective tissue that make up the tooth’s pulp begin to die. If left untreated, the infection can spread out of the tooth and into the bone of the jaw. This may lead to further problems, including the development of a painful abscess, and eventual loss of the tooth.
Root canal treatment involves gaining access to the infected pulp tissue through a tiny hole made in the tooth, and then removing it. Next, the space inside the tooth is disinfected and filled with sterile material, and the access hole is closed. Afterward, a crown or “cap” is often needed to protect the tooth and restore it to full function in the mouth.
One factor that can influence how long a treated tooth will last is how soon the tooth is restored following the root canal procedure: The sooner it receives a permanent filling or crown, the longer it is likely to last. Another factor is whether or not the underlying infection has spread into the bone of the jaw: A tooth that has received RCT promptly, before the infection has had a chance to spread, is likely to have greater longevity.
Some of the other factors that may influence the longevity of a tooth after RTC are: the location of the tooth (front teeth are easier to treat and receive less biting force than back teeth); the age of the individual (teeth become more brittle over time); and what other work needs to be done on the tooth (such as the placement of posts, which may in time weaken the tooth’s structure.) In general, however, there’s no dispute that a tooth which has received a quality root canal treatment should last for many years to come — if not an entire lifetime. And to many people, there’s simply no substitute for having your own natural teeth.
