Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth which is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.
There are several diagnostic tests that can aid in the diagnosis of the dental pulp and the surrounding tissues. These include:
- Palpation (this is where the tip of the root is felt from the overlying tissues to see if there is any swelling or tenderness present)
- Mobility (this is assessing if there is more than normal movement of the tooth in the socket)
- Percussion (TTP, tender to percussion; the tooth is tapped to see if there is any tenderness)

What Happens During a Root Canal?
A root canal requires one or more office visits and can be performed by a dentist or endodontist. An endodontist is a dentist who specializes in the causes, diagnosis, prevention, and treatment of diseases and injuries of the human dental pulp or the nerve of the tooth. The choice of which type of dentist to use depends to some degree on the difficulty of the root canal procedure needed in your particular tooth and the general dentist’s comfort level in working on your tooth. Your dentist will discuss who might be best suited to perform the work in your particular case.
The first step in the procedure is to take an X-ray to see the shape of the root canals and determine if there are any signs of infection in a surrounding bone. Your dentist or endodontist will then use local anesthesia to numb the area near the tooth. Anesthesia may not be necessary, since the nerve is dead, but most dentists still anesthetize the area to make the patient more relaxed and at ease.
- Next, to keep the area dry and free of saliva during treatment, your dentist will place a rubber dam (a sheet of rubber) around the tooth.
- An access hole will then be drilled into the tooth. The pulp along with bacteria, the decayed nerve tissue and related debris is removed from the tooth. The cleaning out process is accomplished using root canal files. A series of these files of increasing diameter are each subsequently placed into the access hole and worked down the full length of the tooth to scrape and scrub the sides of the root canals. Water or sodium hypochloriteis used periodically to flush away the debris.

- Once the tooth is thoroughly cleaned, it is sealed. Some dentists like to wait a week before sealing the tooth. For instance, if there is an infection, your dentist may put a medication inside the tooth to clear it up. Others may choose to seal the tooth the same day it is cleaned out. If the root canal is not completed on the same day, a temporary filling is placed in the exterior hole in the tooth to keep out contaminants like saliva and food between appointments.
Needing a crown after a root canal depends highly on the location of the tooth in the mouth—teeth towards the back of the mouth like molars and premolars are needed more for chewing, and generally require crowns, where incisors or canines which aren’t needed for chewing don’t always require crowns.
Between a root canal and a tooth extraction, a root canal is often the preferred choice because it works on fixing your natural tooth so that it could remain in place. … If a tooth is far too compromised, your dentist might recommend an extraction, followed by a dental implant to replace what was lost.
What You Should NOT eat: It is generally wise to avoid hard, crunchy, and chewy foods in the days following a root canal for recovery to go smoothly. Immediately after the procedure, avoid hot food to prevent burning your lip, tongue or cheek.
If a root canal becomes infected again after a root canal has been done, it’s often because of a problem near the apex of the root. Your dentist can do an apicoectomy to fix the problem so the tooth doesn’t need to be extracted. … In many cases, a second root canal treatment is considered before an apicoectomy.
