AnswerstoCommonQuestionsAboutRootCanalTreatments

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.

NoGleeinToothGrinding

Sure, it’s big news when celebs tweet selfies from the dental office… if you’re still living in the 20th century. But in Hollywood today, it’s harder to say who hasn’t posted snaps of themselves in the dentist’s chair than who has. Yet the pictures recently uploaded to Twitter by Mark Salling, the actor and singer who regularly appears as Noah “Puck” Puckerman on the popular TV series Glee, made us sit up and take notice.

“Getting my chipped tooth fixed. Also, apparently, I’m a big grinder,” read the caption. The photo showed a set of upper front teeth with visible chips on the biting surface. What’s so special about this seemingly mundane tweet? It’s a great way of bringing attention to a relatively common, but often overlooked problem: teeth clenching and grinding, also called bruxism.

Although bruxism is a habit that affects scores of people, many don’t even realize they have it. That’s because the condition may only become active at night. When the teeth are unconsciously ground together, the forces they produce can wear down the enamel, cause chipping or damage to teeth or dental work (such as veneers or fillings), or even loosen a tooth! While it’s common in children under 11 years old, in adults it can be a cause for concern.

Sometimes, mouth pain, soreness and visible damage alert individuals to their grinding habits; other times, a dental professional will notice the evidence of bruxism during an exam or cleaning: tooth sensitivity and telltale wear and tear on the chewing surfaces. Either way, it’s time to act.

Bruxism is most often caused by stress, which can negatively impact the body in many ways. It may also result from bite problems, the overuse of stimulating substances (caffeine, alcohol, tobacco, and illegal drugs), and as a side effect of certain medications. Sometimes, simply becoming aware of the habit can help a person get it under control. Common methods of stress reduction include exercise, meditation, a warm bath or a quiet period before bedtime; these can be tried while we monitor the situation to see if the problem is going away.

If stress reduction alone doesn’t do the trick, several other methods can be effective. When bruxism is caused by a minor bite problem, we can sometimes do a minor “bite adjustment” in the office. This involves removing a tiny bit of enamel from an individual tooth that is out of position, bringing it in line with the others. If it’s a more serious malocclusion, orthodontic appliances or other procedures may be recommended.

When grinding is severe enough to damage teeth or dental work, we may also recommend a custom-made night guard (occlusal guard), which you put in your mouth at bedtime. Comfortable and secure, this appliance prevents your teeth from being damaged by contacting each other, and protects your jaw joints from stresses due to excessive grinding forces.

Whether or not you have to smile for a living, teeth grinding can be a big problem. If you would like more information about this condition, call our office to schedule a consultation for a consultation.


SavingaDiseasedPrimaryToothCouldMeanBetterOralHealthLaterinLife

It’s often best health-wise to preserve even the most troubled tooth—including a child’s primary (“baby”) tooth. If that sounds like too much effort for a tooth that lasts only a few years, there’s a big reason why—if it’s lost prematurely, the incoming permanent tooth above it could erupt out of position.

Preserving a decayed primary tooth could include procedures similar to a root canal treatment, commonly used in adult permanent teeth with inner decay. However, we may need to modify this approach to protect the primary tooth’s pulp. This innermost layer plays a critical role in early dental development.

Because an adult tooth has reached maturity, removing diseased pulp tissue has little effect on its permanent health. But the pulp contributes to dentin growth (the layer between it and the outer enamel) in primary and young permanent teeth, so removing it could ultimately compromise the tooth’s long-term health.

Our goal then with a child’s tooth is to remove as much diseased tissue as possible while involving the pulp as little as possible. What techniques we use will depend on how much of the pulp has become infected.

For example, if decay has advanced to but hasn’t yet penetrated the pulp, we may remove all but a small amount of the decayed structure just next to the pulp to avoid its exposure. We may then apply an antibacterial agent to this remaining portion and seal the tooth to curb further infection.

If on the other hand the pulp has become infected, we may try to remove only the infected portion and leave the remaining pulp intact. We’ll only be able to do this, however, if we deem the remaining pulp healthy enough to remain infection-free after the procedure. If not, we may need to remove the entire pulp as with a traditional root canal. This option, though, is a last resort due to the possible effect on dentin growth and the tooth’s long-term health.

As you can see attempts to preserve a primary tooth can be quite involved. But if we can help it reach its full life span, it could mean better dental health for a lifetime.
