Root Canal Therapy

Each tooth contains pulp tissue which provides it with the nutrients, blood supply, and sensory innervation. When the pulp tissue is infected or becomes damaged, a root canal treatment can be performed by getting rid of the infected pulp, cleaning the canal and sealing it for protection. Smiles on Queen offers root canal therapy to treat painful and infected teeth, allowing us to preserve your natural teeth without extraction.

Do you need root canal treatment?

There are different ways to determine if you are suffering from pulp tissue damage. Some individuals may experience:

  • Pain when biting down or chewing food, or simply to touch and pressure
  • Spontaneous, persisting pain
  • Hypersensitivity to temperature, such as when taking hot or cold drinks
  • Facial swelling, abscess, presence of pus

Should you experience any of the symptoms above, visit Smiles on Queen immediately.

Benefits of root canal treatment

When the pulp tissue is irreversibly inflamed, infected or necrotic, the tooth cannot heal on its own. It will need to be treated to restore your dental health. If left untreated, an infected pulp could result in:

  • Abscess that forms at the root of the tooth
  • Deterioration of bone tissue
  • Pain and discomfort

Unfortunately, the infection could spread fast to other areas of the body leading to systemic illnesses, blood poisoning and fevers. You may also experience swelling on the face and neck because of an infection in your mouth, which could become serious if it affects your airways.

What to expect during root canal treatment

Root canal treatments are performed under local anaesthesia (plus sedation as required) with proper isolation of the tooth to prevent contamination of the canal system during treatment (use of a barrier that covers the mouth). Many patients who require root canal treatments come in with pain, and will actually experience significant relieve following the procedure. In certain instances, multiple appointments may be required to complete a root canal treatment.

First, the dentist will make an opening on the top of the root to access the pulp chamber. The dentist will then remove the infected or dead nerve tissue, and the root canal system is cleaned and medicated. Following adequate shaping and sealing of the canal system, the tooth is restored with a filling. Finally, at a subsequent appointment, a crown is placed over the tooth to protect the remaining tooth structure and to restore function/aesthetics.

I am beyond grateful to the staff at the Smiles On Queen. I until the past 6 months had allowed my health and especially my dental health to rapidly decline. I had avoided the dentist for close to a decade and had a lot of fear, shame and embarrassment regarding the state of my teeth. From the moment I entered the office and furthermore on my call to book my appointment I was met with a degree of compassion and understanding that quite honestly has left me overwhelmed. The care, patience and expertise of the hygienist was extraordinary. Additionally the receptionist was equally as kind and understanding. Thank you - you have done so much for my self esteem - I can smile again without having to worry about the appearance of my teeth. I would highly recommend this office to anyone.

I was referred to this office by a friend because they offer IV sedation. I was very anxious at the dentist before but I was able to remove my wisdom teeth and I did not feel pain or discomfort. The dentist Dr. Lawrence was confident and told me what I was to expect afterward in terms of minor swelling and they also told me to come back if I have any problems but I am fine and happy. Overall I am happy this office was able to see me and they are great.

This dental office is staffed with some of the best people you will ever meet. First of all I would like to say that I’m really afraid dentists (I think its dentistophobia 😊), I've been to over 5 different ones with the same negative results from all. My mother is a cancer survivor and suggested that I check out her dental I did. I was greeted by a team of fantastic people concerned with nothing but my well being. These people are angels sent here to help others in a time of difficulty, it is, honestly an absolutely amazing place.

My experience with both Dr Hung and Dr Norsen has been great and their office staff are very welcoming! I was well informed in details of my treatments and felt safe and secure for them to perform it. Both dentist are very gentle and does a phenomenal job. I was happy with my filling when it was done and I'd recommend these guy to every one. 😄

This was by far one of the best dental experiences I've ever had. I have a huge fear of the dentist and was open about my fears upon arrival. Dr. Norsen was kind, caring and catered to my needs and phobia. I 100% recommend this dental facility. I also felt nothing while receiving my fillings and I'm very hard to freeze and had a lot of work that needed to be done. Over all an awesome experience for the dentist.
