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.

When decay spreads to the tooth’s inner pulp, a root canal treatment may be necessary to save it. It’s a common procedure: after removing all tissue from the pulp, the pulp chamber and root canals are filled with a special filling. The tooth is then sealed and a crown installed to protect the tooth from re-infection and/or fracture, possibly extending the tooth’s life for many years.
Sometimes, however, the tooth doesn’t respond and heal as expected: the number, size and shape of the patient’s root canals may have complicated the procedure; there may have been a delay before installing the final crown or restoration or the restoration didn’t seal the tooth as it should have, both occurrences giving rise to re-infection. It’s also possible for a second, separate occurrence of decay or injury to the tooth or crown to undo the effects of successful treatment.
It may be necessary in these cases to conduct a second root canal treatment, one that may be more complicated or challenging than the first one. For one thing, if the tooth has been covered by a crown or other restorative materials, these will most likely need to be removed beforehand. In cases where the root canal network and anatomy are challenging, it may require the expertise of an endodontist, a dental specialist in root canal treatments. Using advanced techniques with microscopic equipment, an endodontist can locate and fill unusually narrow or blocked root canals.
Because of these and other possible complications, a root canal retreatment may be more costly than a first-time procedure. Additionally, if you have dental insurance, your particular benefit package may or may not cover the full cost or impose limitations on repeated procedures within a certain length of time. The alternative to retreatment, though, is the removal of the tooth and replacement with a dental implant, bridge or partial denture with their own set of costs and considerations.
The complications and costs of a repeated procedure, though, may be well worth it, if it results in a longer life for the tooth. Preserving your natural tooth is in most cases the most desired outcome for maintaining a healthy mouth.

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.
One of the most effective techniques for saving decayed or injured teeth is the root canal treatment. Yet when many people hear they need it, they become nervous at the prospect.
Much of this stems from a common misunderstanding that undergoing a root canal is painful. It’s not — today’s anesthetics are quite effective in numbing pain during a procedure, and mild pain relievers like ibuprofen are usually sufficient to manage any discomfort afterwards.
In fact, a root canal treatment relieves pain caused by decay within a tooth. As decay progresses, it can enter the interior known as the pulp, which contains bundles of nerves and blood vessels. It attacks these nerves causing pain and infection. If the infection progresses through passageways known as root canals that are in the roots of the tooth, the pain can intensify. More important, the tooth is in danger of loss as the root and connective tissues that hold the tooth in place are injured from the spreading infection.
During a root canal treatment, we access the pulp by drilling a small access hole, usually in the biting surface or in the rear of a front tooth. Once we enter the pulp chamber we remove all the contaminated tissue. Once thoroughly cleansed, we fill the empty chamber and canals with a special filling (usually gutta percha) to prevent future infection. The access hole is then sealed and at a subsequent visit we strongly recommend placing a permanent crown to provide further protection from damage to the tooth.
Root canal treatments are quite common. All general dentists have been trained in endodontic treatment and can perform most types of procedures. More difficult cases (like a complex root canal network that may be hard to access) may require the services of an endodontist, a specialist in root canals. Endodontists use advanced techniques and specialized microscopic equipment to treat complicated situations.
It’s actually good news if we recommend you undergo a root canal treatment — it means your tooth has a good chance of survival once it’s disinfected and the decay is removed. But don’t delay: the sooner we can treat your tooth, the better your chances of a healthy outcome.
