IfatAllPossiblePrimaryTeethareWorthSaving

Primary (baby) teeth might not last long, but their impact can last a lifetime. Their first set of teeth not only allows young children to eat solid foods, but also guide permanent teeth to form and erupt in the proper position.

Unfortunately, primary teeth aren't immune to tooth decay. If the decay is extensive, the tooth may not last as long as it should. Its absence will increase the chances the permanent teeth won't come in correctly, which could create a poor bite (malocclusion) that's costly to correct.

If a primary tooth is already missing, we can try to prevent a malocclusion by installing a “space appliance.” This keeps nearby teeth from drifting into the empty space intended for the permanent tooth. The best approach, though, is to try to save a primary tooth from premature loss.

We can often do this in much the same way as we would with a permanent tooth — by removing decayed material and filling the prepared space. We can also perform preventive applications like topical fluoride or sealants that strengthen or protect the tooth.

It becomes more complicated, though, if the pulp, the interior of the tooth, becomes decayed. The preferred treatment for this in a permanent adult tooth is a root canal treatment. But with a primary tooth we must also consider the permanent tooth forming below it in the jaw and its proximity to the primary tooth. We need to adapt our treatment for the least likely damage to the permanent tooth.

For example, it may be best to remove as much decayed structure as possible without entering the pulp and then apply an antibacterial agent to the area, a procedure known as an indirect pulp treatment. We might also remove only parts of the pulp, if we determine the rest of the pulp tissue appears healthy. We would then dress the wound and seal the tooth from further infection.

Whatever procedure we use will depend on the extent of decay. As we said before, our number one concern is the permanent tooth beneath the primary. By focusing on the health of both we can help make sure the permanent one comes in the right way.

YouMayNeedanEndodontistforaToothWithInteriorDecay

You depend on your family dentist for most of your oral care. There are some situations, though, that are best handled by a specialist. If you or a family member has a deeply decayed tooth, for example, it might be in your long-term interest to see an endodontist.

From the Greek words, endo ("within") and odont ("tooth"), endodontics focuses on dental care involving a tooth's interior layers, including the pulp, root canals and roots. While general dentists can treat many endodontic problems, an endodontist has the advanced equipment and techniques to handle more complex cases.

The majority of an endodontist's work involves teeth inwardly affected by tooth decay. The infection has moved beyond the initial cavity created in the enamel and dentin layers and advanced into the pulp and root canals. The roots and underlying bone are in danger of infection, which can endanger the tooth's survival.

The most common treatment is root canal therapy, in which all of the infected tissue is removed from the pulp and root canals. Afterward, the empty spaces are filled and the tooth is sealed and crowned to prevent future infection. General dentists can perform this treatment, primarily with teeth having a single root and less intricate root canal networks. But teeth with multiple roots are a more challenging root canal procedure.

Teeth with multiple roots may have several root canals needing treatment, many of which can be quite small. An endodontist uses a surgical microscope and other specialized equipment, as well as advanced techniques, to ensure all of these inner passageways are disinfected and filled. Additionally, an endodontist is often preferred for previously root-canaled teeth that have been re-infected or conditions that can't be addressed by a traditional root canal procedure.

While your dentist may refer you to an endodontist for a problem tooth, you don't have to wait. You can make an appointment if you think your condition warrants it. Check out the American Association of Endodontists webpage www.aae.org/find for a list of endodontists in your area.

Advanced tooth decay can put your dental health at risk. But an endodontist might be the best choice to overcome that threat and save your tooth.

DespiteSomeOnlineSourcesRootCanalsDontCauseDisease

The internet has transformed how we get information. Where you once needed to find an encyclopedia, telephone directory or library, you can now turn to your handy smartphone or tablet for the same information.

But this convenience has a dark side: A lot of material online hasn’t undergone the rigorous proofreading and editing published references of yesteryear once required. It’s much easier now to encounter misinformation—and accepting some of it as true could harm your health. To paraphrase the old warning to buyers: “Viewer beware.”

You may already have encountered one such example of online misinformation: the notion that undergoing a root canal treatment causes cancer. While it may sound like the figment of some prankster’s imagination, the idea actually has a historical basis.

In the early 20th Century, a dentist named Weston Price theorized that leaving a dead anatomical part in the body led to disease or major health problems. In Price’s view, this included a tooth that had undergone a root canal treatment: With the vital pulp removed, the tooth was, in his view, “dead.”

Price amassed enough of a following that the American Dental Association rigorously investigated his claims in the 1950s and found them thoroughly wanting. For good measure, a Journal of the American Medical Association (JAMA Otolaryngology—Head & Neck Surgery) published a study in 2013 finding that not only did canal treatments not increase cancer, but they might even be responsible for decreasing the risk by as much as forty-five percent.

Here’s one sure fact about root canal treatments—they can save a tooth that might otherwise be lost. Once decay has infiltrated the inner pulp of a tooth, it’s only a matter of time before it spreads through the root canals to the bone. Removing the infected pulp tissue and filling the resulting empty space and root canals gives the tooth a new lease on life.

So, be careful with health advice promoted on the internet. Instead, talk to a real authority on dental care, your dentist. If they propose a root canal treatment for you, they have your best health interest—dental and general—at heart.

RootCanalsareaSafeWaytoSaveTeeth

Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.

Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.

So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.

As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.

In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.

Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.

3FactorsThatCouldAffecttheSuccessofaRootCanalTreatment

A tooth with deep decay is in real peril. If the disease isn’t stopped, it can eventually infect the bone and greatly increase the risk of losing the tooth. But tooth decay removal and a root canal treatment can stop advancing decay and resulting infection in its tracks.

During this common procedure we first drill into the tooth to access the inner pulp. After removing the infected pulp tissue, we disinfect and fill the empty chamber and root canals with gutta percha. We then seal the tooth and crown it to protect against re-infection.

But while most root canals are successful and long-lasting, sometimes the tooth becomes re-infected. Here are 3 factors that could affect the long-term success of a root canal treatment.

Early treatment. Like many health problems, the sooner we detect decay and treat it, the better the outcome. A tooth in which the infection has already advanced beyond the pulp is at greater risk for re-infection than one in which the infection is localized in the pulp. Keeping up your regular dental visits as well as seeing the dentist at the first sign of abnormality—spots on the teeth or pain—can increase your chances of early diagnosis.

Tooth complications. Front teeth with their single roots and canals are much easier to access and treat than a back molar with an intricate root canal network. Root canals can also be extremely narrow making them easy to miss during treatment. In cases like this the expertise and advanced equipment of an endodontist (a specialist in root canal treatment) could help increase the odds of success in complex situations.

The aging process. Teeth do wear over time and become more brittle, making them increasingly susceptible to fracture. A previous root canal treatment on an aging tooth might also increase the fracture risk. To avoid this, it’s important for the tooth to receive a crown after the procedure to protect the tooth not only from re-infection but undue stress during chewing. In some situations, we may also need to place a post with a bonded composite buildup within the tooth to give it extra support.

Even if a tooth has these or similar complications, a root canal treatment may still be advisable. The benefits for preserving a decayed tooth often far outweigh the risks of re-infection.
