Why Your Toothache Might be Myofascial Pain (and Nothing to Do with Your Teeth) (Case Study #1)

Case Study Introduction for Myofascial Pain

Many patients come to our dental clinic in hope for pain relief and answers caused by toothaches. This is usually after visiting many other dentists to no avail. The surprising thing is, many of these ‘toothache’ cases that we see have in fact, nothing to do with the teeth at all. Some of the possible causes are Myofascial pain, TMD (Temporomandibular Joint Disorders), or problems with the jaw muscles or bones.

The mouth, also known as the oral cavity (Kamrani and Sadiq, 2023), contains many other important organs such as the teeth, tongue, and ducts of the salivary glands. Our digestive system is an important and complex one, and it all begins with our mouth. The joints that hold these organs in our mouths together are delicate, fine and sensitive. Pain within our mouths can be hard to decipher with the intricate connections. Many moving parts are also hidden from our sight.

Patient Profile & Toothache Pain Symptoms

Madam Tan (not her real name) is in her 50s, and was in great pain from a persistent toothache. She believed that the pain came from an upper right molar tooth. Before she visited my dental clinic, she had already seen a general dentist plus two endodontists, who are root canal specialists.

Molar Tooth Pain Symptoms

Some of the symptoms for molar tooth pain include:

As you can see from this long list of symptoms, such pain can be tricky to diagnose for a few reasons. For one, they affect all areas of the mouth. For another, they can overlap with many other disorders or causes of chronic pain.

The Patient’s Description of Her Chronic Toothache Pain

Madam Tan described her pain as a deep, dull ache on the right side of her head and face. Chronic pain is pain that persists for three months or longer; she experienced this debilitating pain at least thrice a week. Each episode could last for hours at a time, causing her great distress and limited her quality of life.

Dental Treatments for Molar Tooth Pain She Had Tried

When her pain intensified, Madam Tan underwent a root canal treatment in an attempt to stop the pain. To her dismay, the treatment did not work and the pain returned. Her endodontist then referred her to my clinical practice for further investigations.

Investigations We Took at Nourish Dental Sleep & TMJ Care

To pin down the root cause of the problem, I started by taking an x-ray. It showed no discernible problems with her teeth, including the areas where the pain was coming from. We also conducted other dental tests, yet none of them showed an abnormal result. It was therefore, not a dental issue.

Narrowing Down the Cause of General Toothache to Myofascial Pain

Upon further investigation and more dental tests, we found that she was actually suffering from TMD, or Temporomandibular Joint Disorder. Some of the pain in her jaw muscles were mimicking a toothache. This is also known as ‘Muscle (Myofascial) Toothache’ in informal terms.

The Challenge in Diagnosing Myofascial Pain & TMD

‘Toothache’ cases such as Madam Tan’s can be a challenge to diagnose with all the overlap in symptoms, and the complexity of our oral cavities. It can be difficult to pinpoint what and where the pain is truly coming from.

As a result, many people undergo unnecessary dental procedures, and suffer needless chronic pain. They try root canal treatments, tooth extractions, prosthodontic treatments and more. Yet none of these dental treatments provide them with the pain relief they seek.

This is because the root cause of their chronic pain isn’t addressed; their teeth may not even be the culprit. Chronic pain in our mouth area can stem from our muscles, ligaments, joints, jaws, and more. All these mouth structures need to be further examined. Especially when clinical tests show that ‘nothing is wrong’ with our dental health.

Toothache Awareness & TMD Therapies

Madam Tan is now on appropriate therapies to help control her pain. TMD pain manifests in different ways for every patient, so the treatment plan needs to adapt as well.

Both the patient and dental practitioner need to be aware that the cause of a toothache might not be from the teeth. The head and neck areas are complex anatomical regions; they contain a myriad of structures apart from our teeth. Pain can translate along any part along this pathway.

The reverse can also be true, where dental pain – a real toothache – can mimic muscular pain or even headaches.

For example, we had a patient who had excruciating jaw and neck pain and headaches that was actually due to TMD and comorbidities. And a patient who actually had Facial Migraine which manifested as teeth pain.

Myofascial Pain and TMD Can Be Tricky to Diagnose & Treat

Chronic pain such as myofascial pain and TMD can be tricky to diagnose and treat. When in doubt, always consult a trained pain management dentist. Our focus at Nourish Dental Sleep & TMJ Care, Singapore, is in the proper diagnosis, management and treatment of orofacial pain, which includes TMD / TMJ Disorders, myofascial pain and pain and sleep dentistry.
