A root canal treatment is a commonly known but often misunderstood procedure. Contrary to popular belief, these treatments aren't painful — in fact, they often stop a toothache. More importantly, a “root canal” can give a tooth on the verge of loss another lease on life.
Still, if you've never experienced a root canal treatment before, you probably have questions. Here are the answers to a few of the most common.
Why do they call it a “root canal”? This is the popular shorthand term for a procedure that removes diseased tissue from a decay-infected pulp, the innermost part of a tooth and the actual root canals themselves. Root canals are the narrow, hollow channels that run from the tip of the root to the pulp and are also involved in the procedure.
Why do I need one? Once infected, the pulp's bundles of blood vessels, nerves and other tissues become diseased. This often results in a painful toothache that can also suddenly disappear once the nerves within the pulp die. But there's still a problem: If we don't clean out the diseased and dead pulp tissue, the infection could spread through the root canals to the bone and endanger the tooth's survival.
What happens during the procedure? After deadening the tooth and surrounding gums with local anesthesia, we enter the pulp through an access hole we create. Using special instruments we remove the diseased tissue and shape the root canals to seal them with a filling material called gutta percha. Sealing the access hole is then necessary to prevent re-infection. Later we'll cap the tooth with a porcelain crown to restore its appearance and add further protection against fracture or cracking of the tooth.
Who can perform a root canal treatment? In many cases a general dentist can perform the procedure. There are some complex situations, however, that require a root canal specialist with additional training, expertise and equipment to handle these more difficult cases. If your tooth is just such a case it's more than likely your general dentist will refer you to an endodontist to make sure you get the right kind of care to save it.

Teeth can take a lot of force over a lifetime of biting and chewing, thanks to enamel, their outer layer made of the strongest substance in the human body. Unfortunately, they’re not invincible: it’s even possible for you to break or “fracture” a tooth while biting or chewing normally.
Although such a fracture might seem to occur out of the blue, it’s usually related to a condition known as cracked tooth syndrome. It usually occurs in three stages: in the first, miniscule cracks in the outer enamel known as craze lines develop. They’re not immediately dangerous since they only involve the enamel surface; but left untreated they could deepen and progress to the next stage, a larger crack that penetrates the tooth’s underlying dentin.
If allowed to grow, this crack in turn can lead to the third stage, a full fracture that could extend down to the root. A fracture can put the tooth in danger of loss, especially if its inner pulp becomes exposed. To avoid this worst case, it’s best to treat the tooth at the earliest stage possible when craze lines are just developing.
There is a difficulty, though, with detecting craze lines — they’re small, too small to detect normally with x-rays. We, therefore, rely on other methods such as using an instrument called an explorer to feel for cracks, having the patient bite on a stick or rubber pad to replicate pain symptoms or using fiber-optic lighting with special dye stains to highlight possible cracks. Endodontists, specialists in root canals, can use microscopic equipment that’s quite adept at detecting craze lines.
There are also some signs you can be on alert for that might indicate a craze line or crack. If you feel a short, sharp pain — a “wince” — when chewing and releasing food, you could have a crack that hasn’t yet affected the nerves. If a true fracture occurs, the pain will intensify and you may notice pieces of the tooth coming off. If the crack extends to the root, the pain will become greater and more chronic.
It’s important then that you see us for any recurring pain symptoms as soon as possible. If it’s a crack, the sooner it’s treated the better your tooth’s chances for survival.
