TMJ Disorder Treatment in Cornwall
If your jaw clicks when you chew, aches when you wake up, or triggers headaches that never quite go away, the problem may be your temporomandibular joint. At Cornwall Dental Arts, we provide TMJ treatment in Cornwall that starts with a careful diagnosis and focuses on conservative, comfortable relief — so jaw pain stops running your day.
What is a TMJ disorder?
The temporomandibular joints (TMJ) connect your jaw to your skull, just in front of your ears, and they work every time you eat, speak or yawn. When the muscles and joints of the jaw stop working smoothly, the result is a temporomandibular disorder (TMD) — often just called a TMJ disorder.
Common symptoms include:
- Pain or tenderness around the ears and jaw joints
- Clicking or popping sounds when chewing or yawning
- Difficulty or limited movement when opening and closing the mouth
- Headaches, neck aches, earaches or ringing in the ears
- Pain that radiates into the face, neck or shoulders
Common causes range from teeth grinding and clenching (bruxism) — often driven by stress — to a physical injury to the jaw or head, arthritis in the joint, or displacement of the disc inside the joint itself. Chronic TMD pain can also take an emotional toll, and stress in turn tends to make symptoms worse, so managing the cycle matters.

What we offer
How a dentist treats TMJ disorders
Because your bite, your teeth and your jaw joints all work as one system, your dentist is often the right first stop for TMJ symptoms. Depending on your diagnosis, treatment at our Cornwall office may include:
-
Custom night guards and splints.
A precisely fitted dental splint or night guard cushions your teeth and reduces the clenching and grinding forces that overload the joint — for many patients, this alone brings significant relief.
-
Bite adjustment and corrective dental treatment.
When an uneven bite is contributing to joint strain, carefully adjusting how your teeth come together can take pressure off the TMJ. Orthodontic treatment may be recommended for bite issues that need more correction.
-
Guided self-care.
We'll coach you on jaw-friendly habits: softer foods, heat and cold packs, gentle stretching, posture awareness and stress-management techniques that reduce clenching.
-
A coordinated plan.
Every treatment plan is built individually. Where it helps, we work alongside your physician or physiotherapist — and in rare, severe cases that don't respond to conservative care, we can discuss referral for further intervention.
Why choose Cornwall Dental Arts
Dr. Steven Deneka (DDS, Western Ontario, 1985; KOIS Center graduate) and Dr. Justin Lee (DDS, University of Toronto, 2016) take jaw pain seriously — the exam is thorough, the explanation is plain-language, and the plan starts with the most conservative option that will work. Patients come to us from Cornwall, Long Sault, Morrisburg and across SD&G for exactly that approach.
And because clenched-jaw patients are often tense patients, our office is built for calm, with clear explanations, flexible pacing and a team that listens. If dental visits themselves make you anxious, ask about sedation dentistry.
What to expect at your TMJ assessment

A personalized plan.
Most patients start with conservative care — a custom splint, self-care guidance, or a bite adjustment — with clear follow-up to confirm it's working.
Common questions
FAQ
How do I know if I have a TMJ disorder?
The telltale signs are pain or tenderness near the jaw joints and ears, clicking or popping when you chew or yawn, difficulty opening your mouth fully, and frequent headaches or neck aches. If you notice several of these together — especially with morning jaw stiffness — it's worth booking a dental assessment.
Can a dentist really treat TMJ problems?
Yes. Dentists treat the most common drivers of TMD — grinding, clenching and bite problems — with custom splints, night guards and bite adjustments, and they can coordinate referrals when other therapies are needed. A thorough dental examination is the recommended first step toward an accurate diagnosis.
Can TMJ disorders go away on their own?
Mild TMJ flare-ups sometimes settle with rest, soft foods, heat or cold packs and stress reduction. But symptoms that persist for weeks, keep returning, or come with clicking and restricted jaw movement usually need professional care — untreated grinding, in particular, continues to damage teeth and strain the joint.
Do night guards actually help with jaw pain?
For patients whose TMD is driven by clenching or grinding, a custom-fitted night guard is one of the most effective treatments available — it cushions the teeth and reduces the muscle forces loading the joint while you sleep. Drugstore guards fit loosely and can even worsen symptoms, which is why we make custom mouthguards from precise impressions of your teeth.
Why does my jaw click when I chew — should I worry?
Clicking or popping happens when the disc inside the joint moves out of its normal position as your jaw opens. Painless, occasional clicking isn't always a problem, but clicking with pain, locking, or limited movement is a sign of TMD that deserves an examination.
When should I see a dentist about jaw pain in Cornwall?
Book an assessment if jaw pain lasts more than a week or two, keeps coming back, wakes you at night, or comes with headaches, ear pain or trouble chewing. Early treatment is simpler and more conservative — call our Cornwall office and we'll get you examined promptly.
