A Complete Guide to the 4 Stages of a Root Canal Treatment

root canal treatment eliminates bacteria from an infected root canal to save the natural tooth and prevent reinfection. In a root canal procedure, the infected or inflamed pulp is removed, the tooth is cleaned and disinfected and then filled and sealed. A root canal treatment is a routine dental procedure to treat a diseased tooth. Every year, millions of teeth are treated and saved, in addition to relieving pain. 

4 Stages of a Root Canal Treatment:

A root canal is a minor dental procedure, here is a step-by-step overview of what to expect during a root canal:

Stage # 1: 

The tooth will be numbed with local anesthesia. A small hole will be drilled in the tooth to expose the canals. 

Stage # 2:

In the next step, a series of files are used to clean out the infection, smooth and reshape the canal. 

Stage # 3:

The canals are then sealed with a biocompatible material. 

Stage # 4:

A temporary filling or crown are placed to protect the tooth. Your dentist will call you back for a follow up to receive a customized crown on the treated tooth. 

What is a root canal procedure like?

Prior to a root canal an X-ray is taken to see the size and shape of the root. The X-ray also highlights signs of infection and whether it has spread to surrounding bone. This is either done at the previous appointment or right before the procedure. The dentist will also give local anesthesia to numb the tooth and the surrounding area, so you don’t feel any pain. In addition, a dental dam which is a small sheet of rubber is placed around the tooth to keep the area free from saliva, clean and dry during the procedure. 

One the area is numb; the dentist will create a small opening in the infected tooth using a dental drill and use root canal files to do a pulpectomy. A pulpectomy or a root canal is done to save and repair an infected or decayed tooth. In this procedure, the nerve and pulp of the tooth are removed, and the inside of the tooth is cleaned. The tooth is then sealed. 

The dentist will then fill the root canals with a material to seal them. If the infection or damage in the tooth is severe, the dentist will place a temporary filling or dental crown. At the next appointment, expect to get a permanent filling or crown.

How long does it take to recover from a root canal? 

Although you will be numb for 2 to 4 hours after the procedure, you can return to work or school that day. After the procedure, you should avoid chewing hard foods. If your dentist has placed a temporary crown, then you should not be chewing from that side at all until you receive the permanent crown. 

Pain and sensitivity from a root canal are always mild and similar to what you experience after a filling. Over-the-counter pain medications should help ease any pain or discomfort after the procedure. However, if you have continued pain or notice any swelling, contact your dentist immediately.

Importance of early detection and treatment 

One of the most important factors that impact the success of a root canal treatment is the timing of treatment. Hence, early detection is the difference between a successful treatment and the need for more invasive treatments. Why is early detection critical? 

To avoid further damage 

When a tooth is infected or damaged, the issues should be addressed immediately. The longer the problem is left untreated, the more damage it causes. This leads to requiring more extensive procedures and higher chances of developing complications. In addition to this, it also results in a longer recovery period. Early detection can help avoid further problems and make the treatment process more effective. 

Prevents the need for more invasive treatments 

In some cases, if the infection can spread to other parts of the tooth and other teeth if the infection is not detected early. This may lead to the need for more invasive treatments, for example, extractions or even gum surgery. Thus, early detection decreases the risk of spread of infection and reduces the need for more invasive treatments. 

Improves the success rate of the root canal 

Detecting the problem early improves the success rate of root canal therapy. This helps ensure that the procedure can be performed before the damage is too extensive and the tooth can be saved. 

How to detect these problems early? 

Regular dental check-ups 

The best way to detect a dental problem at its earliest is by visiting the dentist for regular check-ups. During the appointment the dentist will examine your teeth and gums and looks for signs of damage or infection. They will also take X-rays to check the insides of your teeth. The checkup can help catch problems before they become too serious. 

Pay attention to symptoms! 

Another way to detect a problem early is by paying attention to your symptoms. Common signs of a tooth infection include tooth sensitivity, persistent bad taste in the mouth and pain on chewing. If you experience any of these symptoms, see your dentist as soon as possible. This will help the dentist diagnose the problem and determine the best course of action. 

Take care of your oral health 

This cannot be stressed enough, taking care of your teeth is the first step to early detection. Brush and floss your teeth daily. Avoid foods and drinks that can cause damage to your teeth. Taking care of your oral health reduces the risk of developing dental problems and makes it easier for the dentist to diagnose any issues that may arise. 


When it comes to root canal therapy, early detection is critical. It helps avoid further damage to teeth and reduces the need for invasive treatments. It also improves the success rate of the procedure. Regular dental checkups, paying attention to your symptoms and taking care of your oral health can help detect problems early. Further making sure that the root canal therapy is successful.
