Your Teeth

root canal therapy

Root canal treatment (Endodontics) is a dental procedure used to treat infection at the center of a tooth.


The infection is caused by bacteria that live in the mouth and invade the tooth. This can happen after:

  • Tooth decay
  • Leaking fillings
  • Damage to the teeth as a result of trauma, such as a fall

When root canal treatment is needed

Root canal treatment is required when dental x-rays detect that the pulp has been damaged by a bacterial infection. The pulp will begin to die if it’s infected by bacteria, allowing the bacteria to then multiply and spread.


The symptoms of a pulp infection include:

  • Pain when eating or drinking hot or cold food and drink
  • Discomfort when biting or chewing
  • Loose tooth/teeth
  • Swelling of the gums near the affected tooth
  • Pus oozing from the infected tooth
  • Facial swelling
  • Tooth discoloration

As the infection progresses, these symptoms often disappear as the pulp dies. Your tooth then appears to have healed, but the infection has in fact spread through the root canal system.

It’s important to see your dentist if you develop a toothache. If your tooth is infected, the pulp can’t heal by itself. Leaving the infected tooth in your mouth may make it worse. There may also be less chance of the root canal treatment working if the infection within your tooth becomes established.

How Root Canal Therapy is Performed

To treat the infection in the root canal, the bacteria needs to be removed. This can be done by either:

  • Removing the bacteria from the root canal system (root canal treatment), or removing the tooth entirely (extraction).
  • Removing the tooth is not generally recommended as it is better to keep as many of your natural teeth as possible.

After the bacteria have been removed, the root canal will be filled and the tooth sealed with a filling or crown (which is the case in most treatments). Crowns bring back the strength of the tooth and prevent fractures that can frequently lead to extraction.

Before having root canal treatment, you’ll usually be given a local anesthetic. This means the procedure shouldn’t be painful and should be no more unpleasant than having a filling.

    cavities & fillings

    When it comes to cavities, we believe that early intervention is key — enabling you to save money on treatment and improve the longevity of the tooth over time. This is one of the reasons that regular visits to the dentist is important, as every check-up includes procedures which can identify the issue before it becomes problematic.

    Unless specified, we use white fillings for their conservative approach and bonding capabilities. Aesthetically speaking, white fillings blend in with the natural tooth and are virtually invisible to the untrained eye.

    District Dental is proud to use Admira Fusion (BPA Free) — an all-ceramic based material free of classic monomers used in traditional resin composites. Although safety of other composite materials is well proven, the use of Admira Fusion eliminated any possibility of even trace amounts of BPA by-products which can be left behind after the filling is set.


    When it comes to your wisdom teeth, first a careful examination is done to assess the need for extraction. There are a number of things to consider before the decision is made to remove them, leave them, or monitor.

    The most common reasons for extracting wisdom teeth are:

    • Infection of the gums around the wisdom tooth. When there is not enough room for the wisdom tooth to come in, it becomes partially erupted, which means there is often more gum tissue around it. This in turn creates bacteria trap between the tooth and the gum, which is impossible to clean properly. Often times, it’s only a matter of time before an infection develops. This infection can cause severe pain and swelling, and can even be life threatening if not managed properly.
    • For the same reasons of not being able to clean properly, the wisdom tooth can decay and even worse, it can cause the neighbouring tooth to decay and require an extraction as well
    • Bone loss in the area surrounding the wisdom tooth can occur
    • Cysts can form around impacted wisdom teeth, which are fluid filled masses that can degrade bone and/or neighboring teeth. Although more rare, tumors can also develop.

    When should you check the state of your wisdom teeth?

    • We start to monitor them closely from your mid teens to early twenties. This is usually the optimal window for removal to allow for the most conservative surgery as possible, best healing due to young age and lower chance of complications.
    • If you are in this age range, it’s very important to determine the course of action in terms of when and how your wisdom teeth are removed. When you see us at District Dental, we will discuss with you all the details of your individual case and provide you with your best treatment options.

    Dental implants

    Missing teeth have many implications depending on where in the mouth teeth are lost, reason for tooth loss, and the condition of the remaining teeth. The benefits of dental implants essentially come down to improving chewing ability, maintaining a proper stable bite, keeping a healthy and comfortable jaw position, minimizing jaw bone resorption, and of course physical appearance.

    Improving physical appearance with implant-supported teeth, is not always just about replacing teeth that are visible when you smile. In the case of a bite collapse, a person has had missing teeth for a long time where there has been tooth shifting and/or grinding; or there is complete tooth loss. This can cause the lower one third of the face to look shorter and disproportionate to the rest of the face. Re-establishing the bite can dramatically change the way a person looks and can even make one look younger.  

    A number of functional/physiological benefits can also be achieved depending on the specific case. However, everybody is different and presents with a unique set of conditions. Therefore we have to do a thorough examination to determine what these conditions are and what kind of implant therapy would be most beneficial to you.

    For your implant procedure, we first take a 3D scan (Cone beam CT) of your jaw to visualize all vital structures, the amount of bone, and different characteristics of the bone. Based on this information we plan the direction/angulation/length/width/type of implant, and the restorative plan that will optimize the functional and aesthetic outcome of your case.


      Dental crowns are a unique procedure because they functionally replace a tooth without actually extracting the original one. This is possible because crowns are basically tooth-shaped caps: they fit snugly over a tooth and seamlessly blend in with the rest of the mouth. To the untrained eye, the crown is undetectable, and allows for better speaking and chewing.

      So, why are dental crowns useful? The presence of the crown means that any problems with the underlying tooth — fractures, cracks, or lack of enough healthy tooth structure — are covered by the hard ceramic cap and the interior protected and strengthened from any further damage. Dental crowns can be used both as a cosmetic procedure, and as a restorative technique.

      Dental crown is a fantastic solution on its own, but it also plays a huge role in another cosmetic treatment called the dental bridge. Crowns are designed to fix individual teeth, but bridges have a slightly different function — they replace missing teeth by filling the toothless gap with a prosthetic tooth.

      These prosthetics can be fashioned from a variety of materials, the most common of which today is high-strength white ceramic called zirconia oxide.

      The prosthetic tooth acts as the “bridge” part of the dental bridge, but how is it actually attached in the mouth? That’s where dental crowns come in. The natural tooth crowns of the teeth on either side of the toothless space are prepared to accommodate artificial crowns and the bridge is cemented in place as one piece prosthetic. The drawbacks to the dental bridge as a tooth replacement solution are: that supporting abutment teeth have to be filed down, even if they are perfectly healthy and special attention technique is required when flossing around the bridge.


      Why go to the dentist for a second visit if you don’t have to? District Dental offers CEREC single-visit tooth restorations.

      What is CEREC?

      CEREC (Chairside Economical Restoration of Esthetic Crowns) is an advancement in oral health technology which allows the dentist to restore damaged teeth in one visit — effectively eliminating unnecessary costs and stress. This restoration is metal-free, and the high grade ceramic material used is compatible with the natural tissues found in your mouth.

      The procedure begins, like all of our services at District Dental, with an initial consultation with the dentist. During this time he will answer any questions you may have, and discuss the details of the procedure. Following the consultation, we will use a special 3D camera to take video of your tooth — this video enables the CEREC software to properly design your restoration according to your tooth’s appropriate form and function. Once this is complete, CEREC uses diamond burs to create your restoration out of a piece of ceramic. Finally, the ceramic restoration is bonded to your tooth using the latest materials in the adhesive dentistry.

      Why choose CEREC?

      • Time Saving — CEREC crowns are made in one visit, saving you time away from your job and family
      • Comfortability — with CEREC there is no need for a temporary crown, eliminating significant and potential discomfort
      • Aesthetically Pleasing — the strong, tooth-coloured ceramic materials of CEREC restore your teeth to their natural strength, beauty and function, and closely match the composition of your natural tooth structure
      • Durability & Strength — CEREC crown material used is most similar to your own enamel as far as wear, esthetics, and flexural strength. Although proper guidelines and minimal requirements have to be followed in order to guarantee good long-term results, not every patient will be a candidate for such restoration
      • Inlay/Onlays — CEREC material and technology can also be used for replacement of a large portion of the tooth without the need to grind down the whole tooth for a full crown. Multiple factors have to be considered if you are a candidate for such a restoration.

      Digital Evaluation of your bite

      T-Scan technology by Tekscan allows for digital analysis of the bite to assist in diagnosis and treatment of tooth and jaw related problems. The compact sensors utilized in the assessment can measure and record multiple aspects of patient’s bite, including:

      • Level of force during biting and chewing
      • Precise pressure on different parts of a tooth
      • Timing of the contact of individual teeth

      How does T-scan help me? 

      The pressure and timing of the bite can have a big impact on various aspects of your mouth. When teeth are misaligned or are under repeated excessive forces, in other words an unbalanced bite, can result in:

      • Tooth sensitivity
      • Jaw/tooth pain
      • Reduced chewing ability
      • Abfractions (notches along the gum line)
      • Recession
      • Bone loss and tooth mobility

      By performing a T-Scan of your bite, we are able to see exactly where the imbalance of the bite is happening in order to correct the underlying problem.
