If you have persistent jaw pain after getting a root canal treatment or RCT done, it is common and can be a temporary discomfort. However, if the jaw pain after root canal persists for more than a week, it may show signs of infection or complications from the treatment. If you are in such a situation, then this blog is for you. Here are a few insights on how to deal with the aftereffects of an RCT and what to expect post treatment.

Why is Root Canal Treatment Suggested?

Beneath the hard layer of your tooth, there is a mass of soft tissue known as the pulp, which may get inflamed due to various reasons like infections or tooth decay. If the inflamed or infected pulp is left untreated, then it can lead to serious damage.

The endodontist is a specialist for RCT and carefully cleans and shapes the under mass beneath your teeth. The cavity is then filled again and sealed, later placing a crown to restore the teeth and prevent further damage. While this process is done, you may have some level of pain after RCT for a few hours or days, depending on the severity.

After Effects like Pain after a Root Canal Treatment

Generally, after an endodontist conducts an RCT on your teeth you may feel discomfort, pain or swelling among other side effects. This is common and will subside after a while. Here are a few side effects related to RCT-

Discolouration of teeth
Allergic reaction to medication
May experience nerve damage, numbness, tingling sensation
Swelling in your jaw and gums
May get ulcers in your inside cheek
Jaw pain after root canal
Pain or tenderness on the treated tooth
Sensitivity to hot or cold temperature food and drinks

What is Normal in Experiencing Pain after RCT?

Once you get an RCT done, you are bound to experience pain and discomfort for a few days which will subside gradually within the next fifteen days. There may also be physical changes like swelling and redness in the treated area surrounding the tooth.

When does Jaw Pain after Root Canal Become a Concern?

If your jaw or tooth pain after a root canal treatment does not reduce even after fifteen days of the procedure, then it becomes a cause for concern. At this point, it is crucial to consult your orthodontist if you have observed any or all the below symptoms-

Swelling in the face
Excruciating pain inside the mouth near the tooth or jaw
Difficulty in opening the mouth
pain after RCT spreading to nearby areas
Popping sound of the jaw while opening the mouth
Difficulty in chewing food

Is TMJ Disorder Suspected in these Conditions?

With symptoms mentioned above remaining after your RCT, it may be a sign of an existing TMJ issue. Temporomandibular joint disorders affect the jaw and surrounding muscles leading to severe pain and discomfort in following daily routines. Here are a few reasons why jaw pain occurs after RCT-

During the RCT, you have to keep your mouth wide open for a long period, straining the jaws and muscle joints. This action may trigger TMJ symptoms in susceptible patients.
Stress and anxiety are caused while the procedure takes place triggering TMJ symptoms in weak individuals.
Timing and coincidence are also a possibility while jaw pain after root canal cannot be related to TMJ symptoms.

Differentiating Between Pain after Root Canal and TMJ Pain

It can be to differentiate between regular post RCT pain and TMJ pain. Below is a simple guide to refer and differentiate between the two-

Reason	Post-Root Canal Pain	TMJ Pain
Location	Usually localized to the treated tooth and surrounding area	May occur in the jaw joint, temple, ear, or neck
Type of Pain	Dull ache, throbbing, sensitivity to pressure	Can be sharp, aching, or radiating
Duration	Typically subsides within a few days	Can be chronic or intermittent
Other Symptoms	May have some swelling or sensitivity in the gums	May have clicking/popping sounds, limited jaw movement

Conclusion

While jaw discomfort or pain after a root canal treatment persists after many days, accompanied by TMJ pain and other symptoms, it should be evaluated by a dentist and suggest the right cure. In case early diagnoses of TMJ is done, then seek help from a TMJ specialist who will suggest the appropriate recovery plans.
