In Hamilton Victoria Dentists, all our root canal therapy are performed under microscope.
When a cavity is too large or deep and is very close to the nerve then a filling will not be an appropriate fix. This is simply because the nerve will die in the process of preparing the tooth. Other reasons for a root canal is that the tooth has been knocked or for some reason the nerve has died. In all of these situations it is best to take out the nerve and clean the canals in the tooth. A root canal is needed when a tooth’s pulp becomes infected. When this happens, you will likely have some or all of the following symptoms:
-Prolonged tooth sensitivity to hot or cold
-Discoloration of a tooth
-Swelling and tenderness in the gums
-A persistent pimple on the gums
It needs two to three appointments, each procedure takes approximately 45mins to 1 hour a time,. This will vary on a case by case basis depending on the severity of the inflammation and infection. For the last appointment the dentist will make sure the canals are dry and free of infection and will then pack and seal the tooth. After a root-canal has been performed the patient will be advised to get a crown on that same tooth within the following year or so. The reason for this is that because there is no nerve in the tooth now, it will most likely become brittle and will be prone to breaking or cracking if biting down on hard surfaced food.
