Many patients are surprised to learn that modern root canal treatment feels very similar to getting a regular filling.
We take digital X-rays to assess the infection and evaluate the tooth structure.
We completely numb the area to ensure you feel comfortable throughout the procedure.
The infected pulp is carefully removed from inside the tooth.
The canals are cleaned, shaped, and disinfected to eliminate bacteria.
The inside of the tooth is sealed to prevent future infection.
In most cases, a crown is placed to restore strength, function, and appearance.

This is the number one question we hear, and we understand why. The short answer? No. Root canal therapy is designed to relieve pain, not cause it. At Leslie North Dental, we take a comfort-first approach from the moment you walk in.
Before we begin, the area around your tooth is fully numbed using effective local anesthesia. This ensures you don’t feel pain during the procedure. We take our time to make sure you are completely comfortable before starting. Most patients say the treatment feels similar to getting a filling, not the scary experience they imagined.
If you feel anxious about dental treatment, we offer sedation options to help you relax throughout your appointment. Whether you experience mild nervousness or strong dental anxiety, our team will discuss the best option for you and make sure you feel safe and calm.
Knowing what will happen can make everything feel easier.

FAQs
Not to worry, with the benefit of local anesthesia, most people claim that a root canal is no more painful than a tooth filling!
At our dental clinics, you have been prescribed some painkillers to handle the minor pain that may be experienced a few hours after undergoing root canal therapy in Newmarket.
The health care provider applies local anesthesia to numb the affected area of the tooth undergoing the root canal.
The subject tooth is isolated with a rubber dam to protect the surrounding teeth and tissues from saliva and bacteria.
On the subject tooth, the dentist creates an opening to access the root canal system and the compromised pulp.
With delicate hands and specialized tools, the dentist cleans out the pulp and slightly enlarges the root canal system.
After the canal is cleared, the dentist fills the void and seals the canal. The opening of the tooth is also sealed with a temporary or permanent dental filling.
Your Newmarket endodontic treatment will be completed in a stress-free environment if you make a phone call to visit us at Leslie North Dental.
After the root canal treatment, the dentist may refer to a prosthodontist specializing in tooth restoration. The dentist may then apply a dental crown or permanent filling to return the tooth to its naturally aesthetic and functional form. The restoration method depends on how strong the remaining parts of the tooth are post-root canal treatment. Typically, the back molar teeth will require a crown since chewing applies a lot of force on those teeth. Our Newmarket root canal experts specialize in preventing urgent dental issues during your treatment. They will also teach you some simple tips to speed up your recovery time after your treatment. Therefore, you can return to your normal life and join your favorite activities.
