Your temporomandibular joints sit just in front of each ear and connect your lower jaw to your skull. You use them every time you talk, chew, yawn or swallow. When the joints or the muscles that move them are strained, the result is usually called “TMJ”, although the clinical term is temporomandibular disorder, or TMD.
TMJ problems are common, and many people improve with simple, conservative care. The key is recognising the symptoms early and understanding what is driving them.
Common TMJ symptoms
Symptoms vary a lot from person to person. Common symptoms include:
- Jaw pain or tenderness, especially in the muscles at the side of the face or just in front of the ear
- Pain that spreads to the ear, temple, neck or shoulders
- Clicking, popping or grating when you open or close your mouth
- A jaw that feels stuck or will not open fully, sometimes called locking
- Headaches, often at the temples and often worse in the morning
- Soreness or fatigue when chewing, particularly with tough or chewy food
- Worn, chipped or sensitive teeth from clenching or grinding
- A bite that suddenly feels different
Clicking on its own, without pain or restricted movement, is common and often not a concern. It is worth mentioning at your next visit so it can be monitored.
What causes TMJ problems?
There is rarely a single cause. Many cases involve several factors working together:
- Clenching and grinding (bruxism). Many people clench during the day without noticing, and grind at night while asleep. This overworks the jaw muscles and loads the joints.
- Stress. Tension often shows up in the jaw first.
- Bite and tooth position. How your teeth meet can affect how your jaw muscles work.
- Injury. A blow to the jaw, or even a long dental appointment with the mouth held open, can aggravate the joint.
- Arthritis in the joint itself.
- Posture, especially long hours with the head pushed forward at a screen.
- Sleep and breathing. Night-time grinding can be linked with disrupted sleep and airway problems, which is one reason we look at breathing as part of a jaw assessment.
When to see a dentist about jaw pain
Book an assessment if:
- Jaw pain or headaches last longer than two weeks
- Your jaw locks, catches or will not open fully
- Chewing is painful or tiring
- You notice worn, flattened or cracked teeth
- You wake with a sore jaw or headache on many mornings
- Someone has told you that you grind your teeth at night
If your jaw is locked open or closed and will not release, treat it as urgent and call us the same day.
What you can do at home
While you wait for an appointment, these steps often ease symptoms:
- Eat softer foods and cut food into smaller pieces
- Avoid chewing gum and very chewy foods
- Use a warm compress on sore muscles, or a cold pack if there is swelling
- Support your jaw when you yawn
- Practise “lips together, teeth apart”. Your teeth should only touch when you swallow or chew
- Build in small breaks from screens and check your posture
- Wind down before bed to reduce night-time clenching
How a dentist assesses TMJ
A thorough TMJ assessment looks beyond the sore spot. It usually includes:
- A conversation about your symptoms, sleep, stress and habits
- Gentle examination of the jaw joints and the muscles of the face and neck
- Measuring how far and how smoothly your jaw opens
- Checking your bite and looking for wear patterns on your teeth
- Imaging, when needed, to look at the joint itself
The goal is to understand whether the problem is mainly muscular, mainly in the joint, or both, because that shapes the treatment.
TMJ treatment options
Many people do well with conservative treatment. Options include:
- A custom night guard (occlusal splint). It protects teeth from grinding and can reduce load on the joints and muscles overnight.
- Habit awareness. Learning to notice and release daytime clenching makes a real difference.
- Physiotherapy. A physiotherapist with jaw experience can help with muscle tension, posture and range of motion.
- Bite care. Where a specific tooth contact is part of the problem, it can be addressed conservatively.
- Therapeutic Botox. For pain driven by overactive jaw muscles and clenching, small doses of Botox can relax the muscle so it cannot clench as forcefully. Relief usually builds over one to two weeks and lasts around three to four months, after which treatment can be repeated if it helped.
Surgery is rarely needed and is reserved for specific joint problems that do not respond to other care.
TMJ and Botox care at Vigée Dental
Dr. Nicole Robins has training in therapeutic Botox and takes a whole-body view of jaw pain, looking at your bite, sleep and airway rather than treating the jaw in isolation. If you are living with jaw pain, clenching or morning headaches, you can learn more about TMJ and Botox therapy or book an assessment online.
Frequently asked questions
Can TMJ go away on its own?
Mild flare-ups often settle within a few weeks with rest and home care. Symptoms that keep returning, or that last longer than two weeks, are worth having assessed so the cause can be addressed.
Is jaw clicking a problem?
Clicking without pain or locking is common and usually harmless. Clicking that comes with pain, catching or a jaw that will not open fully should be checked.
Can TMJ cause ear pain and headaches?
Yes. The joint sits right beside the ear, so jaw problems are often felt as ear pain or fullness. Overworked jaw muscles are also a common source of tension headaches.
Does Botox help TMJ?
For people whose pain comes mainly from clenching and overactive muscles, therapeutic Botox can reduce pain and clenching force. It is not the right choice for every TMJ problem, which is why a proper assessment comes first.
