Jaw pain, clicking, or chronic clenching aren’t just annoying they could be signs of a serious issue with your temporomandibular joint (TMJ). At Trio Dentistry in Mississauga, we frequently diagnose and treat patients with TMJ dysfunction and help them regain comfort through targeted therapies like BOTOX®, night guards, and bite correction.

In this guide, we’ll help you understand the symptoms, causes, and when to seek treatment for TMJ pain.

What to Know About TMJ Pain

  • TMJ dysfunction can cause jaw pain, tension headaches, ear discomfort, and clicking when chewing.
  • Causes range from muscle overuse to bite misalignment or stress-induced clenching.
  • Treatments like BOTOX®, night guards, or a combination can offer relief.
  • Trio Dentistry uses digital diagnostics and tailored therapy to treat TMJ in Mississauga.

What Is the TMJ and Why It Hurts

Your TMJ connects your jawbone to your skull and enables movement for chewing, speaking, and yawning. Dysfunction in this joint or its surrounding muscles can trigger pain, stiffness, or noise.

Common Symptoms of TMJ Pain

TMJ symptoms can be subtle at first and worsen over time. Common signs include:

  • Jaw pain or tightness, especially when waking up or chewing
  • Clicking or popping sounds when opening your mouth
  • Locking of the jaw, either open or closed
  • Headaches or earaches (often mistaken for sinus issues)
  • Facial muscle fatigue or swelling near the jawline
  • Teeth grinding (bruxism), especially at night


If you’ve experienced one or more of these symptoms consistently, it’s time to get a proper evaluation.

What Causes TMJ Disorders?

TMJ dysfunction can result from:

1. Chronic Clenching or Grinding
Stress-induced clenching and bruxism put constant pressure on jaw muscles.

2. Malocclusion (Bite Problems)

An uneven bite can strain the jaw and lead to muscle imbalance.

3. Trauma or Injury

Past jaw injuries or whiplash can affect joint stability.

4. Arthritis or Joint Degeneration

Inflammatory conditions like osteoarthritis can affect the TMJ.

5. Muscle Overuse or Hypertrophy

Enlarged or overworked masseter muscles can lead to chronic pain.

When Should You See a TMJ Specialist?

Seek professional help if you:

  • Wake up with jaw pain or soreness
  • Hear frequent jaw clicking or popping
  • Have difficulty opening your mouth fully
  • Experience chronic facial tension or headaches
  • Notice wear patterns on your teeth
  • Struggle with nighttime grinding


Early treatment can prevent long-term damage to your jaw joints and teeth.

How We Diagnose TMJ Pain at Trio Dentistry

We use a multi-step approach:

  • Comprehensive TMJ exam: Palpation, range of motion, and muscle tenderness
  • Digital bite analysis: Checks for occlusal imbalance
  • Intraoral camera photos: Reveals wear or damage to teeth
  • Medical history: Evaluates contributing stressors, trauma, or habits
