There are five common reasons why root canal treatment fails, but luckily, they are preventable. A root canal is a dental procedure to fix a tooth that cannot be filled or restored any other way. [citation needed], In the early 1900s, several researchers theorized that bacteria from teeth which had necrotic pulps or which had received endodontic treatment could cause chronic or local infection in areas distant from the tooth through the transfer of bacteria through the bloodstream.

Placement of a crown or cusp-protecting cast gold covering is recommended also because these have the best ability to seal the treated tooth. This material must not be used for commercial purposes, or in any hospital or medical facility. gutta percha and root canal sealer cements) can also cause staining.

[33] Therefore, it is very important to have regular X-rays taken of the root canal to ensure that the tooth is not having any problems that the patient would not be aware of. While potentially disconcerting to the patient, having metal inside of a tooth is relatively common, such as with metal posts, amalgam fillings, gold crowns, and porcelain fused to metal crowns. Incorrect instrumentation length can occur, which can be addressed by the modified step back. [37][38] Corticosteroid intra-oral injections were found to alleviate pain in the first 24 hours in patients suffering from symptomatic irreversible pulp inflammation. According to some research, the outcome of this method is better than a root canal procedure performed with gutta-percha. Machine-assisted irrigation techniques include sonics and ultrasonics, as well as newer systems which deliver apical negative-pressure irrigation. The first, referred to as the standardized technique, was developed by Ingle in 1961, and had disadvantages such as the potential for loss of working length and inadvertent ledging, zipping or perforation. To cure the infection and save the tooth, the dentist drills into the pulp chamber and removes the infected pulp. Let your general dentist or endodontist, a dentist who specializes in performing root canal therapy, know so they can rule out a complication or give it the attention needed to help you on the road to recovery. showed that all root canals obturated with gutta-percha and root canal sealer using either lateral or vertical condensation were recontaminated in less than 30 days when exposed to saliva. The rubber sheet helps prevent saliva from entering the root canal. It provides an aseptic operating field, isolating the tooth from oral and salivary contamination. Root canals, and their associated pulp chamber, are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities. The occurrence of file separation depends on the narrowness, curvature, length, calcification and number of roots on the tooth being treated.

There appears to be no benefit from this multi-visit option, however, and single-visit procedures actually show better (though not statistically significant) patient outcomes than multi-visit ones. Then canal is prepared in crown down manner using K-files then follows a "step back" preparation with 1 mm increments with increasing file sizes. There is insufficient evidence to assess the effects of crowns compared to conventional fillings for the restoration of root-filled teeth, decision of restoration should rely on the clinical experience of the practitioner and the preference of the patients.
