What Is A Root Canal?

Root canals are the space inside the hard layers of each of your teeth.

Within each canal, there is a bundle of nerves, blood vessels, and connective tissue that help the teeth to grow and develop. This bundle, called pulp, can become inflamed or infected leading to pain and sensitivity to biting and temperature changes.

Normally, the dental pulp is protected by hard layers of dentin and enamel, but deep decay or fractures due to biting or other trauma can injure the pulp and allow bacteria to enter the chamber.

Endodontic Procedures

Root Canals

The most basic treatment with Endodontics in Calgary is root canal therapy. Each root canal will be cleaned, shaped, and medicated to eliminate bacteria causing infection. When the tooth has healed, a filing material will be placed to reinstate the health of the tooth.

Then, a crown is placed over the tooth for protection and restoration of function and appearance.

Endodontic Retreatment

In some cases, previous Endodontic treatment may need to be retreated. This may happen when the original infection fails to heal or recurs after some time. Other indications for endo retreatment may involve a crack or break on the tooth underneath or decay on the root canal-treated tooth.

Endodontic retreatment is very similar to the initial root canal therapy. The crown will be removed, then all root canals will be cleaned, medicated, and sealed with a new filling, and the tooth will be restored with a new crown.

Root Surgery

A root surgery is also called apicoectomy. This is a process that removes infection on the tooth root that a standard root canal treatment cannot solve.

With this treatment, a minor surgical procedure will be performed. The inflamed gum tissue will be flapped open to gain access to the tooth root. Then, the tip of the root is removed or resected to completely eliminate dental cyst or infection.

Dental Trauma

Accidental blows to the face may cause dental trauma. The tooth may be pushed into the socket, it may crack, or it can be completely knocked out. For these situations, the tooth can still be saved with root canal treatment.

The earlier you are able to visit your Endodontist, the better the chances are for saving the tooth. This is especially for a tooth that is knocked-out from its place. Until you can visit your dentist, you can place the tooth in a container with saliva or full milk so your dentist can try to put it back in place.

Benefits of Root Canal Treatment

Root canal treatment is the procedure between a dental filling or crown and tooth extraction. If the decay or damage is too extensive for simple dental fillings, or if an infection affects the tooth, a root canal is the treatment of choice. But if this is not done immediately, your dentist may recommend extraction.

So, in a way, Endodontics in Calgary prevents the consequences that come with tooth extraction. Other benefits include:

  • Eliminates infection
  • Relieves any pain and inflammation
  • Restores optimal oral health
  • Keeps the teeth in proper alignment by preventing tooth loss
  • Improves the aesthetics and normal tooth functions after final restoration
  • Preserves the health of neighbouring teeth and surrounding gums
  • Prevents serious health complications

Root Canal Treatment Steps

  • During your treatment with us, our dentist will perform a procedure to ensure that you are a suitable candidate for a root canal treatment.
  • Our dentist will then proceed to administer anesthesia around the infected tooth and place a rubber dam near it to keep the area dry. This will ensure your comfort during the procedure.
  • Drilling, which usually takes about 5 minutes, will help clean out any pulp and bacteria inside the tooth. During this step, your tooth will be rinsed with disinfectant to help wash out any debris.
  • The tooth may or may not get resealed, depending on the circumstances of your case. For example, some root canals may take a few visits to complete, in which case a temporary filling will be placed over the hole to be finished in the next visit.
  • If this procedure is completed by a dentist other than your main provider, a procedure report will be sent to your dentist, who will schedule an appointment for you in two or three weeks. During this follow-up appointment, your tooth will be prepared for a crown and you will leave with a temporary crown. One to two weeks later you will have another visit when your permanent crown will be inserted.

Though the pain may subside after the first visit for a root canal, it’s important to finish the procedure to avoid further infection.

Is Root Canal Treatment Painful?

We understand that some patients associate root canal treatment with pain. Because of the presence of infection, local anesthetics directly administered to the tooth may not work. But at Sierra Dental, we employ modern dental solutions to improve your comfort and experience with root canal therapy.

  • Laughing gas – this utilizes nitrous oxide, a gas that helps you relax within minutes of inhalation.
  • Oral sedation – using pills that produce a sedative effect, such as Valium, Halcion, etc., our Endodontist can perform the treatment, and you will not feel any pain.
  • IV sedation – less commonly used but can produce impressive sedation effects to relieve you of anxiety during Endodontic treatment

Discover relatively painless root canal treatment with these sedative dentistry techniques at Sierra Dental. Providing this alongside Endodontics in Calgary puts you in a “sleepy” state wherein you are less aware of the treatment, so you do not experience any pain. Instead, you are in a calm, relaxed peace of mind as your dentist works to save your tooth.

Root canals have gained an unfair reputation with patients.

A dentist may recommend a root canal to a patient after weighing different treatment options. Sometimes, there’s no way around a root canal when it comes to the damaged dental pulp, and ignoring the problem will only result in pain and potential worsening of tooth decay or infection.

The only case where you are not suitable for a root canal is if you have experienced a significant bone loss or decay that makes your tooth not suitable for a crown. If this is the case, our dentists can recommend alternative treatments for you.

The cost of a root canal varies from case to case and includes factors, such as, which tooth needs to be treated and how many canals the pulp has.

A tooth should recover to full usage after a successful root canal procedure and recovery.

Other alternatives are available such as tooth extraction, and root irrigation but these alternatives may be more invasive or won’t provide the same long-term solutions as a root canal. An implant may also be an option that your dentist can discuss with you.

Root canal treatments are typically more cost-effective than tooth removal, followed by a crown procedure.

Post-treatment care for a root canal is relatively straight-forward.

Over-the-counter pain medications may be used to help regulate pain, or stronger pain medication may be prescribed if needed.

In either case, it’s important for patients to closely follow medication instructions and note these medications could make them drowsy.

Tenderness may last for a few days after a root canal.

A few things to notice include swelling in the gums, or if your bite feels uneven.

You should contact your dentist if you have any questions or experience severe pain for more than a few days.

Sierra Dental accepts new patients and takes pride in doing our best to provide comfortable root canal procedures to our patients.

Frequently Asked Questions

Your first visit is typically an endodontic evaluation. This includes 1 or more X-rays, a discussion about any symptoms you may be experiencing, specific testing of the teeth in the area and discussion about possible treatments, including their advantages and disadvantages.

If your dentist thinks root canal therapy is a good solution to treat your tooth, a typical appointment will last 60 – 90 minutes, depending on the complexity of your tooth.

Following a root canal, roughly half of the people will experience no pain, while the other half will experience mild-moderate pain that they can manage with over-the-counter medications like ibuprofen or acetaminophen. About 5% of people experience moderate-severe pain and require prescription medications. Please call any time with questions or concerns about your treatment.

Lastly, all teeth will require a buildup (commonly known as a filling) to close the hole created to remove the nerve. Most teeth will require a crown after a root canal, so it is important that you see your dentist shortly after your treatment is completed. Delay of this process may result in the tooth breaking, so this procedure should not be delayed. Studies show that teeth that are restored within 2 weeks of root canal treatment have the highest success rates.

After your final root canal treatment, the tooth may be sensitive for a few days. You should:

  • Avoid biting down on hard or sticky foods.
  • Take over-the-counter painkillers if you experience some pain or swelling
  • If this persists passed a few days or becomes more severe, you should contact your dentist as soon as possible.

You should maintain excellent oral hygiene habits to avoid the need for further treatment. This includes brushing at least twice daily, flossing daily, avoiding sugary or acidic food and drink, not smoking, and seeing your dentist for regular cleanings.

If you find it hard to sleep, you can adjust your environment accordingly by:

  • Making the room completely dark and cool.
  • Listening to relaxing music or sounds so your thoughts can drift without trying too hard to sleep.
  • Breathing in and out gently to loosen stiff body parts.

Avoid focusing on the pain or discomfort, as this may cause stress, which may make it harder to sleep.

Crowns Are Required to Prevent Tooth Fracture

When a root canal treatment is performed, the dentist creates an access hole through the top of the tooth to ensure the inner pulp can be expertly removed. This process helps to remove any leftover nerve tissue but also hollows out the tooth structure. The hollow tooth structure then becomes more susceptible to fractures over time. By placing a crown on the tooth, the dentist can tie the cusps together and ensure the tooth is much less likely to fracture during day-to-day activities.

Crowns Can Help To Prevent the Failure of the Root Canal

After going through a challenging oral care treatment such as a root canal, the last thing a patient wants is to go for more treatment in the immediate days afterward. However, they may have to if the root canal treatment fails. A root canal may fail if contaminants from the mouth find their way through the dental restoration and into the tooth, potentially causing infection and other dental issues. Crowns can be used to help prevent the failure of the root canal by stopping contaminants from entering the tooth initially, allowing the restoration time to heal. A qualified dentist working with a dental crown can help ensure root canal success and ensure the tooth is healed for the long-term.

In simple terms, a root canal procedure is required when a cavity has been left untreated too long. Cavity fillings are used to fill small holes in teeth in cases where the nerve has not yet been damaged or affected by the cavity. This treatment only takes one visit to your dentist and is rarely painful thanks to freezing.
