Your jaw does a lot of work every day. From talking and yawning to chewing every meal, your jaw joints and surrounding muscles are constantly moving.
When something goes wrong with these structures, it can lead to temporomandibular disorders (TMD), a group of conditions that affect the temporomandibular joints (TMJs), the muscles used for chewing, or both.
TMD can cause symptoms ranging from occasional jaw discomfort to persistent pain or difficulty moving the jaw. Recognizing the signs can help you know when it's time to talk with your dentist.
What Is the TMJ?
The temporomandibular joint, or TMJ, is the joint that connects your lower jawbone to your skull. You have one joint on each side of your face, located just in front of your ears.
These joints allow your lower jaw to move in several directions so you can open and close your mouth, chew, speak, and yawn.
TMJ refers to the joint itself, while TMD refers to disorders affecting the joint and/or the muscles associated with jaw movement. Although people often say "TMJ" when talking about jaw problems, TMD is the more accurate term for the condition.
What Causes TMD?
There isn't always one clear cause of TMD. Problems involving the jaw joints or chewing muscles can be associated with several factors, including:
- Injury or trauma to the jaw
- Arthritis affecting the joint
- Jaw clenching or teeth grinding
- Muscle tension
- Changes in the jaw joint
- Certain dental or skeletal factors
Stress may also contribute to jaw clenching or muscle tension, which can aggravate symptoms in some people.
Importantly, jaw clicking or popping by itself doesn't necessarily mean that you have TMD. Some people have joint sounds without pain or functional problems.
Signs and Symptoms of TMD
TMD can affect people differently. Some common symptoms of TMJ disorder include:
Jaw Pain or Tenderness
You may notice pain or tenderness around your jaw, particularly when chewing, talking, or opening your mouth. The discomfort may be located around the jaw joint, cheek, temple, or surrounding muscles.
Clicking, Popping, or Grinding Sounds
Some people notice clicking or popping when opening or closing their mouths.
Joint sounds can occur without TMD, so a clicking or popping sound alone doesn't necessarily require treatment. However, if the sounds are accompanied by pain, limited movement, or other symptoms, it's worth discussing them with your dentist.
Difficulty Opening or Closing Your Mouth
TMD can sometimes make it difficult or uncomfortable to open your mouth fully. You may feel as though your jaw is stiff or that it doesn't move normally.
In some cases, the jaw may temporarily lock in an open or closed position.
Headaches or Facial Pain
Because the muscles involved in chewing are connected with areas around the face and temples, TMD can sometimes be associated with headaches or facial pain.
Ear-Related Symptoms
Some people with TMD experience discomfort around the ear or a sensation of fullness. However, ear symptoms can have many different causes, so they shouldn't automatically be attributed to TMD.
Changes in Your Bite
Some people notice that their teeth don't seem to come together in the same way they used to. A change in how your bite feels, particularly when combined with other jaw symptoms, should be evaluated.
When Should You See a Dentist?
Occasional jaw sounds without pain or changes in function may not be a cause for concern. However, you should talk with your dentist if you experience persistent jaw pain, difficulty opening your mouth, jaw locking, painful clicking or popping, or changes in how your teeth fit together.
It's also important to have unexplained facial or jaw pain evaluated rather than assuming TMD is the cause. Several dental and medical conditions can produce similar symptoms.
How Is TMD Diagnosed?
Diagnosing TMD starts with a detailed evaluation. Your dentist may ask about your symptoms, when they began, and what makes them better or worse.
They may also examine:
- Your jaw movement
- The muscles around your jaw and face
- Your TMJs
- Your teeth and bite
- Areas of tenderness or discomfort
Depending on your symptoms and findings, dental imaging or additional evaluation may be recommended.
How Is TMD Treated?
Treatment depends on the specific cause and severity of your symptoms. Not every person with TMD needs extensive treatment, and conservative approaches are typically considered first. Depending on the situation, treatment may include:
- Eating softer foods temporarily to reduce strain on the jaw
- Applying heat or cold as recommended
- Practicing jaw exercises or physical therapy
- Addressing habits such as excessive gum chewing
- Managing teeth clenching or grinding
- Using medication when appropriate
- Using an oral appliance in certain situations
- Additional dental or medical treatment when necessary
More invasive treatments may be considered in specific circumstances, particularly when there is significant joint disease or when conservative care hasn't adequately addressed the problem.
Your dentist can help determine which approach is appropriate based on the cause of your symptoms.
