Understanding root canal therapy

Dr. Ramin Mirmooji describes root canal therapy, or “endodontic therapy,” as a procedure to treat a severely decayed tooth. The pulp, or soft tissue at the tooth’s center, becomes infected and needs a professional to remove and replace it with a material such as gutta-percha or another biocompatible material. This treatment is often performed at our Pierrefonds, Quebec, area practice for patients who are interested in avoiding permanently removing an affected tooth.

When is root canal therapy necessary?

If you experience persistent pain in your teeth, there is a chance that you may need root canal treatment. Decaying teeth can lead to infection in one or more of your teeth, which causes inflammation and sensitivity when eating hot or cold foods. In some cases, the damage can become so severe that it requires the removal of the entire pulp inside the tooth and replacement with another material like gutta-percha or mineral trioxide aggregate.

The root canal procedure is explained – what happens, why, and the solution

Root canal – When a cavity progresses beyond the outside of the tooth, which is dead, and reaches the inside of the tooth or the pulp tissue, which is full of nerves, blood vessels, and active cells, the tooth becomes infected. In cases such as these, we have to remove the infected tissue and perform disinfection of the inside of the tooth. This process is called the root canal. What happens during a root canal? We open up the inside. We disinfect copiously in order to make sure that we kill as much bacteria and then fill the space.

Many Happy Faces

Root canal therapy is a very common procedure. It has a reputation of being undesirable and painful. But when done properly it is actually painless. Every tooth in your mouth is composed of a crown and a root. When a cavity or bacteria penetrates the tooth, the root and its nerves become irritated. As a result, the bacteria within the pulp cavity needs to be removed and cleaned in order to restore the tooth to its healthy state. Following the procedure, the tooth is fragile and consequently is restored with the natural crown for a lifetime of durability. Root canals have a success rate of 95% or greater. Most root canal are diagnosed by patients’ sensitivities to a specific tooth. Be sure to consult your dentist any symptoms or discomfort occur.


Root Canal Therapy FAQs

How do I know if I need a root canal?

Dr. Mirmooji recommends a root canal when a tooth’s pulp becomes infected or inflamed from deep decay, repeated procedures, or cracks. Common symptoms that you may need a root canal include persistent tooth pain, sensitivity to temperature, inflamed gums, and darkened teeth. The infection can spread if left untreated, leading to more serious oral health issues. If you’re experiencing these symptoms, Dr. Mirmooji can evaluate if a root canal is needed.

What happens during a root canal procedure at Dr. Mirmooji’s office?

A root canal with Dr. Mirmooji is a straightforward procedure to remove infection and save your natural tooth. First, he numbs the area for comfort. Then, he removes the infected pulp and disinfects the tooth. To stop infections in the future, a biocompatible substance is used to seal the tooth. A custom crown is usually placed to restore strength. The process takes one or two visits and preserves your smile.

Will a root canal be painful?

Many people assume root canals are painful, but with modern methods, tools, and anesthesia, the procedure is no more uncomfortable than getting a filling. Dr. Mirmooji prioritizes patient comfort and uses gentle, precise methods to ensure a stress-free experience. Most patients feel relief from their tooth pain after the infection is removed. If you have dental anxiety, Dr. Mirmooji can discuss sedation options to help you feel more at ease during your treatment.

How long does it take to recover after a root canal?

Recovery is usually quick and mild. Dr. Mirmooji advises patients that they may experience minor soreness or sensitivity for a few days, which they can manage with over-the-counter pain relievers. Most resume normal activities within a day. However, it’s important to avoid chewing on the treated tooth until a permanent crown is placed to prevent damage. If you experience prolonged pain or swelling, contact Dr. Mirmooji for further evaluation.

Is a crown always needed after a root canal?

In most cases, Dr. Mirmooji recommends a crown after a root canal, especially for molars and premolars that endure heavy chewing forces. It strengthens and protects against fractures. A filling may suffice for front teeth with minimal damage. Dr. Mirmooji will assess your tooth’s condition and recommend the best option to restore function and aesthetics.

How long does a root canal-treated tooth last?

With proper care, the treated tooth can last a lifetime. Dr. Mirmooji emphasizes the importance of maintaining good oral hygiene —brushing, flossing, and checkups—is essential. Avoiding hard foods and protecting your teeth from excessive pressure, such as grinding or clenching, can also help prolong the lifespan of your treated tooth. With the right care, your root canal-treated tooth can function like a natural tooth for years.

Are there alternatives to a root canal?

The only real alternative to a root canal is tooth extraction, but Dr. Mirmooji always prioritizes saving your natural tooth whenever possible. Extraction requires an implant, bridge, or denture to prevent shifting. Root canal therapy is the most effective way to preserve your natural tooth structure and avoid more invasive procedures. If you’re unsure whether a root canal is right, Dr. Mirmooji can discuss your options.
