Procedure of Root Canal
What are the steps for Root canal procedure?
Root canal therapy is done in three steps, and it takes between one to three sessions to complete.
1. Cleaning the root canal
First, the dentist removes everything that is inside the root canal.
With the patient under local anesthesia, the dentist makes a small access hole on the surface of the tooth and removes the diseased and dead pulp tissue with very small files.
2. Filling the root canal
Next, the dentist cleans, shapes and decontaminates the hollow area, using tiny files and irrigation solutions. Then, the tooth is filled with a rubber-like material, using an adhesive cement to seal the canals completely.
After root canal therapy, the tooth is dead. The patient will no longer feel any pain in that tooth because the nerve tissue has been removed, and the infection has been eliminated.
3. Adding a crown or filling
However, the tooth will be now more fragile than it was before. A tooth with no pulp must receive its nourishment from the ligament that attaches the tooth to the bone. This supply is adequate, but in time, the tooth will become more brittle, so a crown or filling offers protection.
Until the crown or filling is complete, the patient should not chew or bite on the tooth. Once there is a crown or filling is done, the person can use the tooth as before.
Treatment often takes only one appointment, but if there are curved canals, multi-canals, or large infections, this could take one or two additional appointments.
