DontFeartheRootCanal-itCouldSaveYourTooth

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.

LasersAddingNewPrecisionandEfficiencytoRootCanalTreatments

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.

ASecondRootCanalTreatmentMayHelpSaveanEndangeredTooth

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.
