DontBeWaryofaRootCanal-HeresHowItCouldSaveYourTooth

Here's the bad news: One of your teeth has tooth decay. But here's even worse news: The decay has entered the pulp and root canals in the heart of the tooth. You're well on your way to losing that tooth.

But cheer up—root canal therapy might save your decayed tooth. We use root canal therapy to remove the infection from within a tooth and then fill the resulting empty spaces to prevent further infection. This routine procedure has saved millions of teeth.

But alas, along the way root canals somehow became a cultural symbol for unpleasantness. In reality, there's nothing further from the truth—the procedure itself is painless, and may even stop any pain caused by tooth decay.

So, let's take the mystery out of root canal therapy—the more you know, the less wary you'll feel. Here's what to expect if you undergo this tooth-saving procedure.

Preparation. We start by numbing the tooth and surrounding gums with local anesthesia. While we're waiting for the anesthesia to take full effect, we isolate the tooth with a dental dam to prevent cross-contamination to other teeth.

Access. Next, we drill a small opening into the tooth to access the pulp and root canals. If it's one of the large back teeth, we drill the hole in the tooth's biting surface; in a narrower front tooth, we make the access opening in the rear surface.

Removal. We remove tissue from the pulp and root canals using special instruments. Afterward, we thoroughly disinfect the pulp and canal interiors with an antibacterial solution to ensure we've stopped the infection.

Filling. After re-shaping the root canals, we fill them and the pulp chamber with gutta percha, a rubber-like material ideal for this type of dental situation. We then fill and seal the access hole. In a few weeks, you'll return to have a permanent crown installed to further protect the tooth.

You may have some minor discomfort that's usually manageable with mild pain relievers, and should dissipate over a few days. The good news, though, is that we've more than likely saved a tooth that might have otherwise been lost.

HowAFVsAlfonsoRibeiroSavedHisTooth

Remembered fondly by fans as the wacky but loveable Carlton on The Fresh Prince of Bel-Air, Alfonso Ribeiro is currently in his fifth year hosting America's Funniest Videos. It's the perfect gig for the 48-year-old actor, who loves to laugh and make others laugh as well. This is quite the opposite experience from one he had a few years ago that he remembers all too well: a severely decayed tooth.

After seeing his dentist for an intense toothache, Ribeiro learned he had advanced tooth decay and would need root canal treatment. Ribeiro wasn't thrilled by the news. Like many of us, he thought the procedure would be unpleasant. But he found afterward that not only was the root canal painless, his toothache had vanished.

More importantly, the root canal treatment saved his tooth, as it has for millions of others over the last century. If you're facing a situation similar to Alfonso Ribeiro's, here's a quick look at the procedure that could rescue your endangered tooth.

Getting ready. In preparation for root canal therapy, the tooth and surrounding gums are numbed, often first with a swab of local anesthesia to deaden the surface area in preparation for the injection of the main anesthesia below the surface. A dental dam is then placed to isolate the infected tooth from its neighbors to prevent cross-contamination.

Accessing the interior. To get to the infection, a small access hole is drilled. The location depends on the tooth: in larger back teeth, a hole is drilled through the biting surface, and in front teeth, a hole is drilled on the backside. This access allows us to insert special tools to accomplish the next steps in the procedure.

Cleaning, shaping and filling. Small tools are used to remove the diseased tissue from the interior tooth pulp and root canals. Then the empty spaces are disinfected. This, in effect, stops the infection. Next, the root canals inside the tooth are shaped to allow them to better accept a special filling called gutta percha. The access hole is then sealed to further protect the tooth from future infection, and a temporary crown is placed.

A new crown to boot. Within a couple weeks, we'll cap the tooth with a long-lasting lifelike crown (or a filling on certain teeth). This adds further protection for the tooth against infection, helps strengthen the tooth's structure, and restores the tooth's appearance.

Without this procedure, the chances of a tooth surviving this level of advanced decay are very slim. But undergoing a root canal, as Alfonso Ribeiro did, can give your tooth a real fighting chance.

TheremaybemoretothatToothachethatSuddenlyStopsAching

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.

SettingtheRecordStraightonRootCanalTreatments

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.

RootCanalTreatmentforPrimaryBabyTeeth

If you think your child is too young to need root canal treatment, think again — there is no age limit for this treatment. If his/her primary (baby) teeth have been injured, or if decay has advanced deep into the roots of your child's teeth, a root canal treatment to stabilize teeth may be needed. Root canal treatment removes infection from the pulp, the living tissue that is found inside the tooth's roots. The pulp contains the tooth's nerves, so tooth pain is often an indication that decay has moved into the pulp.

When performing root canal treatment on primary teeth, we must keep in mind that the primary teeth's roots will be resorbed as part of the normal process in which the body makes room for the growing permanent teeth that will take their place.

If a child experiences tooth pain that is related to changes of temperature or pressure, or exposure to sweet or acidic foods, the infection is likely to be minor and easily repaired. But if he or she feels a constant or throbbing pain regardless of stimulation, it may indicate an extensive infection of the pulp and surrounding area.

If the infection is advanced, the baby tooth may have to be removed. But if baby teeth are lost prematurely, a malocclusion (from “mal” meaning bad and “occlusion” meaning bite) can easily result; so we make every effort to keep the baby teeth in place to guide the permanent teeth that are forming underneath them, inside the child's jaw. In such cases an endodontist (from the root “endo” meaning inside and “dont” meaning tooth) or pediatric dentist may perform root canal treatment, removing the diseased and infected pulp from within the tooth's roots and replacing it with a substance that can be absorbed when it is time for the baby tooth's roots to be resorbed naturally.

When baby teeth are injured through a fall or blow to the face (referred to as traumatic injury) they may develop discoloration varying from yellow to dark gray. This is a sign of damage to the pulp tissues inside the tooth's roots. Dark gray discoloration often indicates that the pulp tissues have died. In such cases root canal treatment is needed to remove the dead tissue. If a tooth is completely knocked out of the child's mouth, most dentists agree that it should not be replanted because of the risk of damage to the developing tooth underneath.

Root canal treatment for baby teeth is a better choice than tooth removal if at all possible. It helps a child retain full function of their teeth, jaws and tongue, preventing speech problems, and it helps guide the permanent teeth into their proper places.
