What This Pain Feels Like
A deep, gnawing pain just in front of the ear that intensifies when opening the mouth or chewing. The jaw may click, pop, or catch during movement, and opening wide — such as for yawning or biting into a large sandwich — can feel restricted or even impossible. A dull headache at the temple often accompanies the jaw symptoms. Many patients are diagnosed with TMJ dysfunction, but the lateral pterygoid trigger point is frequently the underlying driver of both the pain and the clicking.
Jaw pain Deep lateral jaw pain from trigger points in the primary jaw-opening muscle
Clicking jaw Jaw clicking can occur with or without pain and does not identify a muscle trigger point. Painless clicking usually needs no treatment; pain or locking warrants a jaw assessment.
Sinus pain Referred pain to maxillary sinus region mimicking sinusitis from pterygoid trigger points
Ear pain Deep ear pain from lateral pterygoid referral to auricular and preauricular region
Difficulty opening mouth Limited mandibular depression from lateral pterygoid trigger point inhibition and spasm
TMJ clicking and popping Jaw clicking can occur with or without pain and does not identify a muscle trigger point. Painless clicking usually needs no treatment; pain or locking warrants a jaw assessment.
Jaw deviation on opening Unilateral lateral pterygoid dysfunction causes the mandible to deviate toward the affected side
Deep facial ache Referral from the inferior head projects deep aching into the maxillary and zygomatic regions
Sensation of sinus pressure Deep facial referral to the maxillary sinus area mimics sinusitis pressure and congestion
Limited mouth opening with pain Trigger point shortening restricts lateral pterygoid excursion limiting condylar translation and opening
If jaw-muscle pain persists, a clinician trained in temporomandibular care can assess whether intraoral manual treatment is appropriate and demonstrate any suitable home technique. Do not probe behind the upper molars to try to find this deep muscle.
Duration
Individualized
Frequency
As advised after assessment
Expect
May ease jaw-muscle soreness and make chewing more comfortable.
Caution Do not force a locked or painful jaw. Report sharp pain, new locking or lasting worsening. Painless clicking alone usually does not need treatment.
Exercises
Jaw relaxation exercise (tongue on palate)
Place the tip of your tongue gently on the roof of your mouth just behind your upper front teeth. Allow your jaw to drop open slightly while keeping your tongue in position — this naturally relaxes the jaw muscles and prevents clenching. Hold this position for 30 seconds, breathing slowly through your nose. Practice this position whenever you notice yourself clenching, grinding, or holding tension in your jaw.
Duration
30 seconds to 1 minute per repetition, 5-10 repetitions
Frequency
Multiple times throughout the day, especially during stressful moments
Expect
Helps you notice clenching and practise relaxing the jaw during everyday tasks.
Exercises
Gentle jaw opening with resistance
Place your fist gently under your chin. Slowly open your mouth against the light resistance of your fist — do not push hard, use only about 20% of your maximum effort. Hold the open position for 5 seconds, then slowly close. Repeat 10 times. This isometric exercise helps retrain the jaw-opening muscles to work smoothly without triggering clicking or catching.
Duration
2-3 minutes per session
Frequency
2-3 times per day
Expect
Aims to build comfortable, controlled jaw movement for eating and speaking.
Lifestyle Changes
Soft diet modification during flare-ups
During periods of increased jaw pain or clicking, switch to soft foods that require minimal chewing — soups, smoothies, scrambled eggs, pasta, mashed vegetables, and yogurt. Avoid hard, crunchy, or chewy foods such as raw carrots, bagels, steak, gum, and hard candy. Cut food into small pieces and chew using both sides of the mouth evenly. Avoid opening the mouth excessively wide for biting.
Duration
Throughout flare-up periods, typically 1-2 weeks
Frequency
Every meal during active symptoms
Expect
Reduces chewing demand during a flare so meals may be more comfortable; return gradually to usual textures.
Lifestyle Changes
Stress and clenching awareness practice
Set reminder alarms on your phone every 1-2 hours throughout the day. Each time the alarm sounds, do a jaw check: Are your teeth touching? Is your jaw clenched? Are your jaw muscles tight? If so, separate your teeth slightly, relax your jaw, and place your tongue on the roof of your mouth. Keep a brief journal noting when you catch yourself clenching — this builds awareness of your personal stress-clenching patterns.
Duration
30 seconds per check-in
Frequency
Every 1-2 hours during waking hours
Expect
Helps you notice clenching and practise relaxing the jaw during everyday tasks.
Professional Treatment
Professional TMJ evaluation
If jaw clicking, locking, or deep jaw pain persists beyond 3-4 weeks of self-care, seek evaluation from a dentist specializing in TMJ disorders or an orofacial pain specialist. They can assess disc position, joint mechanics, and occlusion. Imaging such as MRI may be recommended to evaluate the articular disc. A physical therapist experienced in TMJ rehabilitation can provide targeted manual therapy and neuromuscular retraining.
Duration
Initial consultation typically 45-60 minutes
Frequency
As needed based on symptom severity and persistence
Expect
Comprehensive diagnosis of TMJ mechanics and a targeted treatment plan that may include splint therapy, manual therapy, or other interventions
