A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form. A root canal filling is a way of keeping a tooth, once the live part (the pulp) has become irreversibly damaged.
The aim of the procedure is to painlessly remove the damaged pulp, and remove any infection that may be present. Once the canals have been cleaned and shaped they are filled with a special filling material. Once the root canal filling is in place, the crown of the tooth is restored with a large filling or cast restoration.
Your dentist here removes the entire damaged pulp from the pulp chamber as well as the roots. The roots are then filled (usually with Gutta Percha) immediately or after few dressings of cotton embedded in medicine depending on the extent of infection/necrosis of the tooth. This treatment is called complete Pulpectomy or Root Canal therapy.
During the dressing phase if you neglect to keep your appointment, you may need more appointments and dressings and in such case filling your root canal may become difficult. You must adhere to your appointment schedule especially during this phase. Your tooth is then restored with or without posts, pins etc, as per the discretion of your dentist.
The filling materials we may use are – Gutta Percha, Silver Cones, Composite, Nano Fillers, GIC, Zinc Oxide Eugenol cements, Zinc Phosphate.
