Root Canal Therapy

Our teeth contain long, thin strands of dental pulp which provides the tooth with nutrients and nerves.  The nerves and nutrients are critical during tooth development but afterwards, its purpose is not as critical, and a tooth can remain without this dental pulp.  This dental pulp extends down to the entirety of the length of the tooth from crown to root tip.  If the pulp becomes infected or injured due to decay or trauma respectively, the tooth’s nerve will die.  When this happens, bacteria will invade into this small space called the root canal, leading to pain and infection.  Root canal treatment will often save a tooth when this happens.  During this procedure, the bacteria and dying nerve is removed and retrofilled with a rubber material that will seal this space from becoming reinfected.  With advances in rotary instruments, root canal treatment is not as scary as it used to be.  Often times, it can be done in one appointment and with proper anaesthetic the patient often feels no discomfort and remarks that their experience was no different from a standard filling appointment.

During the procedure, the nerves are accessed through the tooth’s crown and pulp chamber, diseased pulp is removed and reshaped, the tooth is then permanently sealed with a restoration. This allows the tooth to remain in function just as prior to treatment.
