05 Jun Will my tooth need additional treatment following a root canal?
A root canal is a dental procedure where the outer surface of the tooth is opened and the contents of the root’s canals are cleaned out usually due to infection. Without this process, the affected tooth must generally be extracted.
Sensitivity to temperature or sweets is a very good clue that the nerve of a tooth is in jeopardy. Pressure can also be present, and a toothache can be a hint. But there are many other problems where discomfort is a symptom, and the resulting treatment may not involve endodontic therapy (root canal). These may include dental decay or problems associated with gum disease.
When symptoms of any dental problem are experienced, a visit to the dentist is indicated. If your dentist suspects a problem might involve the dental nerve, a simple test is performed by directing cold air at the suspected tooth. The patient’s response will usually confirm a problem.
X-rays will be taken before root canal treatment. Your dental provider will want to see how many roots are involved as well as their placement. When a tooth requires a root canal, it is critical to make sure all roots are treated. If one is missed, the infection can remain requiring re-treatment.
A root canal starts by segregating the affected tooth. The tooth needs to be kept dry and the contents removed are safely disposed of when the tooth is damned off. The next step involves creating an access point in the exterior of the tooth. A special file is then used that allows for the contents of the roots of the tooth to be removed. These contents contain primarily pulp tissue, blood, and nerve tissue.
The access point must be sealed to complete treatment. An anterior tooth may be sealed with a composite resin restoration. Often this can be performed immediately following endodontic therapy.
Most posterior teeth are sealed with a dental crown. This restoration requires a minimum of two dental visits. The involved tooth is prepared, and impressions are taken and sent to the dental lab for fabricating the crown. Treatment is completed when the crown is permanently placed.
