Root canal therapy is a treatment that works on clearing an infection inside of the tooth. When a tooth becomes cracked, the sensitive nerves and blood vessels inside are exposed and can become infected if not treated. Only 2 options become available at this point: extraction and root canal therapy. If you do not wish to lose a tooth, root canal therapy is the choice for you. A general dentist is able to preform this procedure, but for extreme cases, they may refer you to an endodontist, a dental professional who speciailizes on the inner workings of the teeth. The length of time also depends on the severity, ranging from one visit to three visits.
After numbing the area, the dentist will insert a dental dam to prevent any saliva or bacteria from entering the area being worked on. Then, creating a small opening, they will clear out the infected pulp and replace it with a material to protect the root. The filling is then covered by cement. For those prone to infections, a crown may be suggested.
