One of dentistry's most common and effective restorations, root canal therapy--or endodontic therapy--preserves infected, cracked or heavily decayed teeth. A wonderful, comfortable alternative to dental extraction, a root canal treatment take only two visits with your dentists at Ajax Dental Centre. Dr. Saeid Jafarpour, Dr. Kevin Kwong and Dr. Azza Elhaddad qualify patients with oral examination and X-rays, determining if an ailing tooth can be saved. Learn more here.
The root canal procedure
After determining a root canal treatment would help your oral health, the dentist numbs the tooth with locally-injected anesthetic. Then, a protective dam is placed and a small hole- created to access the first of two, three or even four interior chambers, or root canals.
The root canals contain soft pulp which has a blood supply, nerves and connective tissue. This pulp is prone to infection when injured through trauma, decay or even numerous restorative procedures.
During endodontic therapy, your dentist will remove the pulp from each canal using a rotary tool or a series of tiny metal files. He or she will reshape and smooth the canal walls and instill antibiotic medication. A biocompatible putty called gutta percha seals and strengthens each canal, and a temporary filling covers and protects the tooth as it heals.
When you return to Ajax Dental Centre, the doctor will remove the temporary restoration and replace it with a beautifully crafted porcelain crown. The crown blends in with the rest of your smile in terms of color, shape and size. With careful oral hygiene and professional follow-up every six months, the restored tooth can last indefinitely, says the American Association of Endodontists.
Signs you may need a root canal
Many people who need root canal treatments often experience these common symptoms:
- Dental sensitivity to pressure, heat, color or sugar
- A throbbing toothache
- Gum and/or jaw swelling
- Enamel discoloration
- Deep crack or chip
- Bad breath
- A pimple at the gum line
- Red, sore gums
Unfortunately, some patients exhibit no symptoms whatsoever. So, this is why people need routine preventive care at Ajax Dental Centre. Six-month cleanings remove harmful plaque, and regular examinations detect problems as they are developing.

Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
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.

Modern dental care wouldn’t be the same without x-rays. Since dentists began capturing x-ray images a century ago to detect beginning tooth decay, billions of teeth have been preserved.
“Catching it early” is the key to staying ahead of this aggressive bacterial infection. Once it breaks through the protective defenses of tooth enamel, it can advance toward the center of the tooth, the pulp, damaging dentin as it goes. While we can effectively stop it at this point with a root canal treatment, it’s better for the tooth’s long-term health to detect and treat any decay early on with a less-invasive filling or other treatment method.
X-ray imaging helps make that possible, revealing decay much easier than we can see with the unaided eye. And while we can often detect decay in front teeth by visual examination or by using very bright lighting, that’s not as easy with the less accessible back teeth. For those teeth we use a special x-ray technique known as the bitewing.
The name comes from the small frame used to hold the film. It’s held in place in the mouth by the patient biting down on small tabs or “wings” extending from the frame. The x-ray beam travels through the outer cheek and teeth to the film being held in the frame on the back side of the teeth. When exposed, we’ll be able to view the interior of these back teeth: a set of four bitewings gives us a full view of all the upper and lower molars and pre-molars on each side of the jaws.
Like other forms of radiation energy, too much or too frequent exposures to x-rays can lead to serious health problems. But bitewing x-rays carry little risk to health. That’s because they fit well with the ALARA principle, meaning “As Low As Reasonably Achievable,” which helps guide our use of x-rays. Patients receive a fraction of the radiation exposure from routine bitewing x-rays than they receive annually from the natural environment.
Without bitewing x-rays and other diagnostic methods, the chances are high that tooth decay or other dental problems can go undetected in their early stages. Using this important tool can help us head off major damage before it occurs.

Whitening can transform the dullest teeth into a dazzling smile fit for a Hollywood star. But before you undergo a whitening procedure, you might have a few questions about it. Here are the answers to a few of the most common.
How white can I go? In an office application we can adjust the solution and application time to control the level of shade (dark or light) from subtle to dazzlingly bright. The real question, though, is how much color change will look best for you? A good rule of thumb is to match the shade in the whites of your eyes.
Whitening will improve poor dental conditions…right? Not necessarily. Besides foods, beverages or poor hygiene, decay, abscesses or problems from root canal treatments can also cause discoloration. In some dental situations, whitening could make your smile less attractive. If, for example, you have exposed roots due to gum recession, those areas won't bleach like the enamel and could make their exposure stand out more. Better to try and repair these problems before whitening.
What effect will teeth whitening have on my dental work? None â??composite or ceramic materials won't lighten. The real concern is with creating a situation where whitened natural teeth don't match the color of dental work. Depending on the location of your veneers, crowns or other bridgework you could have a color mismatch that will look unattractive. We would therefore need to take your dental work into consideration and adjust the shading accordingly.
Will teeth whitening work on any stained teeth? That depends on the cause of the staining. If it's on the enamel, then external bleaching techniques should work. If, however, the discoloration comes from inside the tooth, then only a dental procedure that applies a bleaching agent inside the tooth can alleviate that kind of discoloration.
So after whitening, I'm good to go? Well, not permanently. Eventually the brightness will diminish or fade, usually in six months to two years. You can, of course, prolong the fade rate by not using tobacco, cutting back on staining beverages like red wine, tea and coffee, practicing daily oral hygiene and visiting us for regular office cleanings and other dental work. We can also touch up your existing whitening during your visits.
