Root canal treatment is indicated when:
Under these conditions, the patient can develop pain and/or a tooth infection (abscess). A root canal treatment will allow the patient to keep the tooth while eliminating the pain, swelling and discomfort associated with it. This allows the patient to retain the natural tooth for chewing and keep their full smile.
Root canal treatment consists of removing the inflamed or infected pulp. Pulp is the soft tissue inside the tooth that contains the nerves and blood vessels.
Once the pulp is removed, the dentist cleans the canal by expanding and disinfecting it. Afterwards, the dentist fills it with cement and rubber (gutta-percha). Once the canal is well cleaned and sealed, the dentist restores the part of the tooth above the gum. At this time, the dentist will perform a conventional restoration, a ceramic restoration or install a crown supported by a pivot.
In case of severe infection, the dentist will have to complete the root canal treatment over two or more sessions in order to treat it properly. Usually, a root canal treatment requires only one session.
