Root canal procedures treat disorders of the nerve of the tooth. This treatment may become necessary because of a variety of factors, some of which are:
- physical irritation (large decay or restorations)
- trauma (cracked tooth or occlusion)
- gum disease.
Root canals are frequently performed in two 1-hour appointments. Pain relief is usually accomplished in the first visit by removing the diseased tissue. At the second appointment the preparation of the root canal is completed and the canal is sealed with a special filling material to keep bacteria from re-entering the tooth. Root canal, or endodontic treatment, may leave the tooth weaker than a healthy tooth. This could ultimately lead to tooth fracture and tooth loss. To help prevent this, a crown restoration is frequently recommended.
