A lot of people associate the words “root canal” with wincing pain. It’s a procedure people would rather not go through. However, people who are told they need a root canal are usually in pain already, requiring thus the use of anesthetic before the root canal procedure to dull the pain. In in its website, WebMD points out the usual instances where a root canal at your local Newmarket dental office would be the procedure of choice over any other general dental treatments:
Root canal treatment (also called a root canal) is done when decay will likely damage or has already killed a tooth. During a root canal, a dentist or endodontist removes the pulp from the center of a tooth and fills the pulp cavity. This can prevent the development of a painful infection in the pulp that may spread to other teeth. A root canal can also treat an infection that has developed into an abscessed tooth. This procedure can relieve toothache, stop infection, and promote healing.
A dentist should first make sure that a root canal is necessary. An x-ray exam and a pulp test will determine this. Pulp tests often involve placing something cold against the tooth to see any nerve response. The lack of response means that the pulp inside the tooth has already died and needs to be removed. If it is extremely painful, on the other hand, it means that the pulp inside is infected and needs to be dealt with, either through removal or treatment. There are different types of pulp tests, depending on the dentist’s approach. The initial evaluation also decides whether the procedure should be done in one or two sessions. Double visits are only needed when a retreatment is necessary.
The root canal process starts with the dentist applying a local anesthetic. They place a rubber dam around the tooth to isolate it, and an opening is made in the tooth, wide enough for the dentist to reach the root canal system and remove the damaged central pulp. The dentist removes the pulp with the use of special instruments, then cleans the area using sodium hypochlorite or other disinfectants. After the canal has been cleaned, the dentist fills up the space and seals it. The tooth opening is sealed with a temporary or permanent filling, then capped with a crown to protect the tooth and the surrounding areas from further infection.
