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.

Less-InvasivePulpCappingCouldSaveYourTooth

There’s one sure thing about tooth decay: you can’t ignore it. In fact, the best outcomes result from finding it early and treating it before it enters the pulp in the center of the tooth, often a filling or similar treatment.

If it does advance to the pulp, you may need a root canal treatment to save the tooth. This is a moderately invasive procedure where we access the pulp and root canals, tiny passageways leading to the root and supporting bone. We then remove all the diseased tissue and fill the empty pulp chamber and root canals with a special filling. Later we’ll crown the tooth for added protection against future infection or fracture of the tooth.

But there’s also another less-invasive method than a root canal called pulp capping. It’s only appropriate to use, however, if the pulp has become exposed or almost exposed by decay, but hasn’t yet shown signs of disease.

Pulp capping can be either direct or indirect. We use direct pulp capping if the healthy pulp has been exposed by the disease process. We first isolate the tooth from the rest of the mouth to prevent contamination and then proceed to remove all of the tooth’s decayed dentin structure. We then apply a biocompatible material directly over the pulp to protect it from further decay and to facilitate healing. We then restore the tooth, usually with a filling, to its proper function and life-like appearance.

When the pulp is threatened by decay but not yet exposed, we may then use the indirect method. In this approach we first remove most of the decayed dentin, but leave a small amount next to the pulp to keep it covered. We then treat this remaining dentin with a material to help it heal and re-mineralize, followed by a temporary filling of the tooth. A few months later we’ll remove this filling and inspect the treated dentin. If it has regenerated sufficiently, we remove any remaining decay and permanently restore the tooth.

As we said, pulp capping is only used with patients with deep decay whose pulp tissue is healthy. But when we can use it we can avoid some of the permanent alterations that often come with a root canal treatment and still save the tooth.
