Root Canal Therapy In Hamilton And Stoney Creek


Dentistry on Queenston's goal is to restore your mouth to the most natural state possible. A tooth that is badly decayed or becomes infected can be repaired and saved through root canal therapy. During the therapy, the nerve and pulp are removed and inside of the tooth is cleaned and sealed. Without the therapy, the tissue surrounding the tooth will become infected and abscesses may form.

Signs that you need root canal treatment include tooth pain, sensitivity to heat and cold, and tenderness to touch and chewing. You should also look for tooth discolouration and tenderness of lymph nodes, gum tissue and bone. However, sometimes infection requiring a root canal can be present with virtually no symptoms at all. 

Root Canal Treatment

A root canal therapy is the most common type of endodontic procedure. It is a routine procedure that relieves pain, saves millions of teeth every year, and can help improve appearance. Often when a tooth has become infected or abscessed as a result of decay or an injury, it is possible for your dentist to save your tooth by performing root canal treatment. (Your dentist may also refer you to an endodontist for treatment.) Root canal procedure becomes necessary when a tooth's pulp becomes inflamed or infected. The infection may arise as a result of conditions such as tooth decay, repeated dental work, or a cracked tooth. If left untreated, the infection may lead to an abscess, a more serious infection that can be even life-threatening. 

During the root canal treatment, on opening is made in your tooth to access the infected nerve, which is then removed. The pulp is fully removed from the tooth, the pulp chamber is cleaned and shaped, and the empty space is filled and sealed. Following a root canal therapy, your dentist may place a temporary seal or a permanent filling over the tooth. Most teeth that have root canal treatment will require a crown .You dentist generally fixes a crown on the tooth to support the remaining tooth structure or performs some other type of restorative work to return the tooth to its full function and appearance. 

After root canal treatment, to avoid fracture or other damage, you must not bit or chew on food with the tooth that has undergone root canal treatment until restoration work has been completed. After the root canal treatment, it is important to follow good hygiene practices.

Root Canal Myths

There are many myths around the root canal therapy such as:

Root canal treatment is painful - Root canal therapy has advanced significantly in the last few years. Modern anesthetics and techniques are generally able to ensure that little pain is felt  during a root canal procedure. The pain you experience during the root canal therapy is not more than the pain you may experience during the filling of a cavity. After a root canal treatment, the tooth and surrounding area may be sensitive which can be treated by prescription medication or by over-the-counter pain reliever. 

Root canal treatment causes illness - This is simply untrue. There is no valid, scientific evidence to prove a connection between root canal therapy and illness.

It's better to pull a tooth than having a root canal - Savings your natural teeth is always the best option. Root canal therapy has a high success rate and many root canal-treated teeth last lifetime. 

Tooth Abscess

A tooth abscess is a pus deposit caused by bacterial infection. Abscesses can occur in any region of the tooth for a number of reasons. Some of the symptoms of a tooth abscess include:

  • severe and persistent throbbing pain radiating to the neck or ear

  • sensitivity to heat and cold

  • sensitivity to pressure when biting or chewing

  • fever, chills, nausea, or vomiting

  • swelling in the face or cheek

  • tender and swollen lymph nodes in the face or neck

  • foul smelling and tasting salty fluid in the mouth


When the above symptoms occur, you must consult your dentist immediately. Your dentist will thoroughly examine your mouth to confirm a tooth abscess and take X-ray to evaluate the spread of infection. Your dentist will drain the pus, wash the area with saline and treat the infection with medication. To save the tooth, a root canal procedure might be necessary and in some cases, the tooth may need to be extracted. Leaving the tooth abscess untreated can lead to life-threatening complications.
