Exercise Daily – If you have pain after root canal how long is the first question that comes to your mind. Because a root canal is a serious treatment, it is typical to have discomfort after it. A root canal is a procedure that includes extensive cleaning within the canals. It may irritate the nerves and tissues in the surrounding area.

The discomfort shouldn’t linger indefinitely. An actual root canal intends to alleviate the discomfort associated with a rotting or cracked tooth, not to cause it. It is typical to suffer mild to moderate discomfort for a few days after a root canal procedure. 

If you have any discomfort beyond this stage, your dentist may recommend further cleaning of the canals or other treatments.

The initial phase of recuperation

It used to be that root canals were very unpleasant. This is one of the reasons why individuals have hung back from such operations in the past. The use of pain-relieving methods by dentists may help to lessen the amount of discomfort you encounter throughout the operation.

Following the root canal procedure, you may feel slight discomfort and sensitivity as the local anesthetic wears off. Pain after root canal how long has something to do with the cleaning procedure.

In the course of the cleaning procedure, your dentist creates a tiny incision in the crown of the tooth. Then, it removes the unhealthy pulp from inside the tooth’s pulp chamber. While it may be painful, any pain or sensitivity experienced after a root canal should subside within a few days.

5 Common Reasons You Have Tooth Pain after Root Canal

Despite the fact that this surgery is quite efficient at alleviating pain, some people still feel tooth discomfort. In this article, we’ll discuss five of the most prevalent reasons why this happens.

Post-Procedure Inflammation Causes Tooth Pain After Root Canal Treatment

A major reason for post-root canal tooth pain is inflammation. It may be caused by the treatment itself or by an infection that has caused the dental ligament to become inflamed. Inflammation is one of the most prevalent causes of post-root canal tooth pain. 

In some instances, the swelling will reduce within a few days or weeks after the root canal. However, the discomfort will subside on its own after the procedure. Pain after root canal how long depends on the extent of inflammation.


A root canal is often done to remove diseased pulp from within the tooth. Hence, it’s conceivable that some germs remain after the surgery. It might result in infected tissue and more discomfort. If this occurs, seek medical attention immediately. 

When your immune system targets and eliminates the germs, the condition should correct itself. However, if the problem continues, your doctor or dentist may prescribe antibiotics.

Oversized Fillings

A rubber-like substance is used to replace the empty area left by your dentist after the pulp has been removed. If an excessive amount of filling material is utilized, on the other hand, the tooth will sit higher in the mouth, causing discomfort whenever you bite down. 

Despite the fact that this condition will not cure on its own, your dentist may simply correct the situation by modifying the filling.

An Incomplete Root Canal

There are certain teeth, particularly molars, that may have several canals. It’s conceivable for a dentist to overlook one or more of these canals during a root canal treatment. In these instances, the underlying cause of the pain is rarely addressed. 

You will continue to experience discomfort even after having a root canal. A similar scenario occurs when you have a damaged nerve within a tooth that has to be removed. You may still suffer pain when the tooth comes into touch with heat, cold, or an acidic substance.

Damage to the Surrounding Tissue

Tissue damage can occur during a root canal procedure if bacteria is accidentally injected into the surrounding tissue. Pain after root canal how long depends on the damage and its extent.

If too much filling material is used and flows past the root tip, or if a file used for cleaning slips beyond the root tip and pokes into the tissue will cause pain. In these instances, the discomfort will subside as soon as the injured tissue has healed.

When should you seek assistance?

The discomfort associated with root canal treatment should diminish with time. If you are still experiencing discomfort or swelling, you should schedule an appointment with your dentist. The majority of patients need one to two sessions in order to have a successful root canal. 

If the situation is serious, you may need more cleaning sessions. Pain after root canal how long that comes and goes might be an indication of this.

If you’re using any over-the-counter pain relievers, you should notice a reduction in your symptoms. Otherwise, your doctor may prescribe ibuprofen or narcotic pain medicines that are only available with a prescription. These are only intended to be used on a temporary basis.

Once your tooth has been fully healed, your dentist may recommend that you have a crown placed on top of it. Metal, porcelain, and gold are all possible materials for them. The goal here is to avoid further harm to a tooth that is already in a vulnerable state. 

Pain may be a transient side effect of getting acclimated to a freshly put crown, and it is normal.
