Clinical Assessment
Example Case
A 38-year-old office worker visits the clinic with recurring jaw discomfort, particularly in the morning and during meals.
“Every time I open my mouth, my jaw makes a clicking sound. Recently, it started hurting when I chew, and sometimes I wake up with a headache. My dentist said I might be grinding my teeth at night. Could that be causing it?”
Initially, the clicking was painless. However, over the past few weeks, chewing has become uncomfortable, and the jaw occasionally feels tight. So, is the clicking actually causing the pain, or is something else happening?
That is where the investigation begins.
Subjective Symptoms
The client reports:
- Clicking when opening or closing the mouth
- Pain around the jaw and in front of the ear
- Morning jaw stiffness and occasional headaches
- Discomfort when chewing harder foods
- A feeling of tension around the cheeks and temples
- Possible nighttime teeth grinding
Interestingly, the client also mentions feeling stressed at work. Although stress may influence jaw-clenching behaviour, it does not automatically explain every symptom.
What It May Feel Like
People with temporomandibular disorders (TMDs) may notice:
- Jaw pain or tenderness
- Clicking, popping or grinding sensations
- Difficulty opening the mouth comfortably
- Pain when chewing or yawning
- Headaches around the temples
- Ear-area discomfort without an obvious ear problem
- Occasional catching or locking of the jaw
Importantly, clicking without pain is common and usually does not require treatment. Therefore, the sound alone may not be the main problem.
*********
Objective Findings
During assessment, the therapist may identify:
- Reduced or uncomfortable mouth opening
- Tenderness around the masseter and temporalis muscles
- Pain reproduced during chewing movements
- Clicking during jaw opening or closing
- Asymmetrical jaw movement
- Associated neck or upper-shoulder tenderness
However, these findings do not establish a diagnosis by themselves. The next question is whether the pain comes mainly from the muscles, the joint or a combination of factors.
The temporomandibular joints (TMJs) connect the lower jaw to the skull and allow movements needed for chewing, speaking and yawning.
TMD refers to a group of conditions affecting these joints, the chewing muscles or related structures. Possible explanations include:
- Muscle-related pain: Increased sensitivity or discomfort in the chewing muscles
- Joint irritation: Pain associated with jaw movement or loading
- Disc-related changes: Altered movement of the joint disc, sometimes associated with clicking or locking
- Headache associated with TMD: Head pain influenced by jaw activity
Nevertheless, dental problems, ear conditions and other sources of facial pain may cause similar symptoms. In other words, not every painful jaw is a TMJ problem.
Several factors may influence symptoms:
- Repeated jaw clenching
- Teeth grinding during sleep
- Frequent gum chewing
- Prolonged or excessive jaw opening
- Previous jaw injury
- Poor sleep and increased stress
- Persistent pain sensitivity
Yet, in many cases, there is no single identifiable cause. Instead, several small factors may interact, making the jaw increasingly sensitive during everyday activities.
The assessment aims to determine:
- Which movements reproduce the symptoms
- Whether the pain appears muscular or joint-related
- How comfortably the client can open and close the mouth
- Whether chewing, clenching or sleep habits influence symptoms
- Whether dental or medical assessment is needed
- How the symptoms affect eating, speaking and daily life
The goal is not simply to stop the clicking. It is to understand why normal jaw movement has become painful or difficult.
For uncomplicated TMD, conservative management is generally the first approach.
Treatment may include:
- Gentle, appropriate jaw mobility exercises
- Temporarily choosing softer foods
- Reducing gum chewing and prolonged clenching
- Avoiding excessive mouth opening
- Heat or cold for symptom relief
- Relaxation and stress-management strategies
- Manual therapy when appropriate
- Dental or medical review if symptoms persist
Initially, reducing irritation may make chewing and speaking more comfortable.
Next, gentle exercises and a gradual return to normal jaw function may help rebuild confidence in movement.
Meanwhile, manual therapy may support pain relief, but it should not replace appropriate dental assessment or active self-management.
Permanent changes to the teeth or bite are generally not recommended as routine TMD treatment.
How Does It Usually Recover?
Many people with uncomplicated TMD improve over time, sometimes without extensive treatment.
At first, the jaw may need temporary relief from activities that repeatedly provoke pain. However, avoiding normal movement indefinitely is not the goal.
As symptoms settle, gentle movement and gradually returning to usual foods and activities can help restore function.
For some people, improvement occurs relatively quickly. Others experience recurring or persistent symptoms that require additional care.
Ultimately, successful recovery means being able to:
Eat without worrying about every bite
Speak and yawn comfortably
Sleep with fewer disturbances
Reduce recurring headaches
Move the jaw with greater confidence
However, a jaw that becomes locked, severe or worsening pain, facial swelling, fever, or unexplained dental symptoms should prompt medical or dental assessment. An inability to close the mouth after a suspected dislocation requires urgent care.
Your Body Talks. Learn to Listen.
A clicking jaw does not always mean something is broken. And pain does not always reveal where the problem begins. Sometimes the answer is not in the sound you hear, but in the patterns you have overlooked.
Listen beyond the click. Understand the movement. Treat the cause not just the noise.
Ask it. Even if you think it’s a ridiculous question.
Someone else has probably wondered exactly the same thing.
