Before even going through a root canal, most people are scared of what to expect after. Given the myth of root canals and excruciating pain, people are unlikely to go through with the surgery. But here’s the thing: root canals do not hurt. If anything, there is just slight discomfort after the procedure.

It is only when the pain gets worse or exceeds the ten-day limit that you should be worried. In such cases, contacting your dentist is the best method. To learn more about what causes pain after a root canal, carry on reading this blog.

Is it Normal To Experience Pain After a Root Canal?

Whether you’re about to get a root canal or just had one, the pain and discomfort that come with it are normal. There is bound to be minor pain after the procedure as your mouth slowly starts to heal. Plus, given how intrusive a root canal is, irritated and inflamed gums are its common after-effects.

This entire ordeal only lasts for a week or two before clearing up on its own. However, if the pain gets too much to bear, you can take over-the-counter pain relievers to help minimize the ache.

Common Causes of Pain After Root Canal

Although pain after a root canal is common, there are cases where it is not always a part of the healing process, but rather one of the following reasons:

Post-op Discomfort

A root canal treatment can be really intense, given how the dentist scoops inside your tooth to get rid of the bacteria. This typically leaves behind a deep pit, which makes the tooth vulnerable to external stimuli. That is why dentists cover the exposed tooth with a filling or crown. Thus the pain you feel is nothing more than your mouth getting used to the new changes.

Dental Infection

Aftercare is an essential part of all dental treatments. Moreover, since root canals remove the bacteria-ridden pulp from the tooth, it is crucial to maintain good oral hygiene. If even a small amount of bacteria remains inside or somehow sneaks in, it can cause severe pain.,

Filling or Crown Too Loose

Sometimes the pain you feel is not because of the infected tooth but rather the crown or filling covering it. A crown that is too big for the tooth can lead to pain and hypersensitivity. Similarly, a loose filling can make it extremely difficult to go about your daily activities. Replacing it with a cover that fits properly is the only way to curb the pain.

Incomplete Procedure

People often think that there is only one canal in the tooth. But that is not true. Molars are known to have multiple canals inside of them. Thus, if the bacteria attack more than one of the canals, it can be difficult to identify their root cause. So, if the dentist accidentally misses one canal while clearing out the rest, the bacteria could get trapped inside, leading to unbearable pain.

Injured Gums or Tissues

Due to the invasive nature of a root canal, it is common for your gums or oral tissues to get injured during the procedure. Once the anesthesia wears off from the surgery, the sudden pain can take you by surprise.


All in all, pain after a root canal is extremely common. Although, if you continue to experience discomfort in the affected tooth weeks after the procedure, let your dentist know. You can also reach out to Signature Smiles for more information at:
