1.  A Deep Infection Root canal treatment is needed when an injury or a large cavity damages the tooth's root. The root becomes infected or inflamed.

2.  A Route to the Root The dentist numbs the tooth. An opening is made through the crown of the tooth to the pulp chamber.

3.  Removing the Infected/Inflamed Tissue Special files are used to clean the infection and unhealthy pulp out of the canals. Then they shape the canals for the filling material. Irrigation is used to help clean the canals and remove debris.

4.  Filling the Canals The canals are filled with a permanent material. Typically this is done with a material known as gutta-percha. This helps to keep the canals free of infection or contamination.

5.  Rebuilding the Tooth A temporary filling material is placed on top of the gutta-percha to seal the opening. The filling remains until the tooth receives a permanent filling or a crown. A crown, sometimes called a cap, looks like a natural tooth. It is placed over the top of the tooth.

6.  Extra Support In some cases, a post is placed into the root next to the gutta-percha. This gives the crown more support.

7.  The Crowning Touch The crown is cemented into place. ROOT CANAL Overview A root canal is a treatment to repair and save a badly damaged or infected tooth. The procedure involves removing the damaged area of the tooth (the pulp), cleaning and disinfecting it and then filling and sealing it. The common causes affecting the pulp are a cracked tooth, a deep cavity, repeated dental treatment to the tooth or trauma. The term "root canal" comes from cleaning of the canals inside the tooth's root. What to Expect During a ROOT CANAL If you think you need a root canal, consult your dentist. There are a number of steps that occur over a few office visits. X-ray – if a dentist suspects you may need a root canal, he will first take X-rays or examine existing X-rays to show where the decay is located. Anesthesia – local anesthesia is administered to the affected tooth. Contrary to popular belief, a root canal is no more painful than a filling. Pulpectomy – an opening is made and the diseased tooth pulp is removed. Filling – the roots that have been opened (to get rid of the disease pulp) are filled with gutta-percha material and sealed off with cement. Tips for Care After a ROOTCANAL A treated and restored tooth can last a lifetime with proper care. Root canals have a high success rate. Here are a few ways to take care of your teeth after a root canal: Practice good oral hygiene – brush teeth twice a day, and floss at least once. Taking care of your teeth can help prevent future problems. Visit the dentist regularly – cleanings and examinations by dentists and hygienists. Avoid chewing on hard foods – chewing on hard foods such as ice can cause teeth to break, and can harm root canals.
