Treatments: TMJ Disorders (Temporomandibular Joint Disorders)

This page describes the treatments for jaw joint and jaw muscle problems, from self-care to surgery, and what the research shows about each.

This page describes the common treatments for temporomandibular joint (TMJ) disorders in adults, meaning problems affecting the jaw joint and the muscles that move the jaw, and what the research shows about each. The condition itself is described on the TMJ disorders conditions page.

The Big Picture

Most TMJ problems improve over time and can be managed without surgery. Care usually starts with the simplest, safest, reversible options and moves toward injections or surgery only if symptoms do not improve. Research consistently shows that the most effective approaches encourage gentle movement, build coping skills and reduce strain on the jaw, rather than relying on any single device, pill or procedure. A combination of treatments, tailored to the individual, tends to work better than one alone.

Self-Care and Jaw Rest

Resting the jaw and avoiding activities that overload it are often the first steps: avoiding wide yawning, gum chewing, nail biting, and clenching or grinding, and letting the jaw muscles relax. Self-care also includes becoming aware of clenching habits during the day and gently correcting them.

What the evidence shows: Self-management advice, reassurance and simple home measures are endorsed as first-line care and are considered a foundation that other treatments build on. The specific benefit is hard to measure precisely, but these measures are low-risk and widely supported.

Soft Diet

Choosing softer foods and cutting food into smaller pieces reduces the force the jaw joint and muscles must generate, giving irritated tissues a chance to settle.

What the evidence shows: A soft diet is a standard part of early care because it lowers the load across the joint during healing. It is commonly used alongside jaw rest, though it is rarely studied on its own.

Heat and Cold

Moist heat can relax tight jaw muscles and ease stiffness, while cold packs can numb pain and calm inflammation. These are often alternated or chosen based on which feels more helpful.

What the evidence shows: Warm moist heat or localized cold may relieve pain enough to make gentle jaw exercises possible. They are considered safe, inexpensive, supportive measures rather than stand-alone cures.

Physical Therapy and Jaw Exercises

A physical therapist or dentist may teach exercises to improve jaw coordination, gently stretch and strengthen the muscles, and restore range of motion. Hands-on ("manual") techniques, including therapist-assisted jaw mobilization and treatment of tender muscle "trigger points," may also be used. Posture training can be part of the program.

What the evidence shows: This is among the best-supported treatment categories. High-quality analyses have found that therapist-assisted jaw mobilization and manual trigger-point therapy are among the most effective options for reducing chronic TMJ pain, and supervised jaw exercise and stretching improve jaw function. Benefits are often greatest when exercises are combined with education and encouragement to stay active.

Oral Splints and Night Guards

A splint (also called an occlusal appliance, bite guard or night guard) is a custom-fitted device worn over the teeth, often at night. It is meant to relax the jaw muscles, protect the teeth from grinding and reduce strain on the joint.

What the evidence shows: Splints are one of the most commonly used TMJ treatments and can reduce pain and ease jaw limitation for some people. However, the overall quality of the evidence is only low to moderate, and their pain-relieving effect appears modest compared with broader pain-management approaches. Splints do not permanently change the bite and are generally used as a reversible, conservative option. Permanently grinding down or reshaping the teeth to "fix the bite" is not supported by evidence.

Medications

Several types of medication are used, usually for short periods and alongside non-drug treatments:

• Anti-inflammatory pain relievers (NSAIDs) such as ibuprofen or naproxen are the most commonly used, aimed at mild to moderate pain and inflammation. Taking them on a regular schedule (rather than only when pain spikes) can help during flare-ups.

• Acetaminophen (paracetamol) may be combined with an NSAID to keep the NSAID dose lower.

• Muscle relaxants may help when muscle spasm and tightness are prominent.

• Low-dose antidepressants (such as tricyclics) are sometimes used for persistent pain.

• Corticosteroids reduce inflammation in certain situations.

• Opioids are generally discouraged because of the risks of tolerance and dependence.

What the evidence shows: The evidence for medications in TMJ disorders is modest and mixed. NSAIDs are reasonable for short-term relief, though studies show inconsistent results. Because all of these drugs have side effects, short-term or intermittent use is preferred, and no single drug has been proven clearly superior for everyone.

Botulinum Toxin (Botox) Injections

Botulinum toxin injected into the jaw muscles can reduce muscle activity and may ease pain, particularly in people with muscle-related jaw pain or heavy clenching and grinding that has not responded to standard care.

What the evidence shows: The evidence is conflicting. Some studies show botulinum toxin reduces muscle-related jaw pain better than placebo, while others, including a Cochrane review, found no clear benefit for myofascial pain. It is not FDA-approved for TMJ disorders (an "off-label" use) and is not a first-line treatment. Repeated injections have been linked to side effects such as muscle thinning (atrophy), reduced bite strength and changes in the underlying jaw bone, so the decision involves careful discussion.

Trigger Point and Joint Injections

• Trigger-point injections place a small amount of local anesthetic (numbing medicine), and sometimes other agents, into tender knots within the jaw muscles. "Dry needling" uses a needle without injecting medication.

• Intra-articular (within-the-joint) injections deliver substances such as corticosteroids, hyaluronic acid (a lubricating gel) or platelet-rich plasma (PRP) into the joint itself, often at the time of a joint washout.

What the evidence shows: Trigger-point injections with local anesthetic and dry needling have shown some benefit, but the supporting evidence is limited. For injections into the joint, hyaluronic acid and PRP have shown promise for pain relief, especially when combined with a joint washout, though results vary by substance and study.

Arthrocentesis (Joint Washout)

Arthrocentesis is a minimally invasive procedure in which needles are placed into the joint space to flush it with sterile fluid. This washes out inflammatory byproducts and debris, improves lubrication, and can free up a joint that is stuck. It is often done under local anesthesia and frequently combined with an injection of hyaluronic acid or PRP.

What the evidence shows: Arthrocentesis is regarded as an effective first-line minimally invasive option, particularly for degenerative (arthritis-type) joint disease and a "locked" jaw. Combining it with injections of hyaluronic acid, PRP or similar agents tends to produce greater, clinically meaningful improvements in pain and mouth opening than washout alone. It is low-cost and has a low risk of complications.

Arthroscopy (Keyhole Joint Surgery)

Arthroscopy uses a thin camera (endoscope) inserted into the joint through a small opening, usually under sedation or general anesthesia. The joint can be inspected, adhesions (scar bands) released, and other minor repairs performed.

What the evidence shows: Arthroscopy is an effective minimally invasive surgical option for internal joint problems. It is more involved and costly than arthrocentesis, which is why arthrocentesis is often tried first. Arthroscopy is generally reserved for cases that do not respond to simpler measures.

Open Joint Surgery and Joint Replacement

Open surgery (arthrotomy) involves a larger incision to directly repair or reposition the disc, remove damaged tissue (such as a discectomy), or reshape parts of the joint. In severe cases where the joint is badly damaged, a total TMJ replacement with an artificial joint may be considered.

What the evidence shows: Open surgery was more common decades ago and is now reserved for advanced joint disease or cases that fail less invasive treatments. Some analyses suggest certain open procedures (such as discectomy) can meaningfully reduce pain and improve mouth opening, but the quality of this evidence is low, and these procedures carry higher risks. Minimally invasive options are therefore generally tried first.

The Role of Stress and Sleep

Stress, anxiety and poor sleep are closely tied to TMJ symptoms. Stress can increase jaw clenching and muscle tension, and ongoing pain can worsen mood and sleep, creating a cycle. Addressing these factors is an important part of treatment and may include relaxation techniques, deep breathing, improving sleep habits, biofeedback (using sensors to learn to relax muscles) and cognitive behavioral therapy (CBT), a structured talk-therapy approach for managing pain and stress.

What the evidence shows: This is one of the strongest areas of evidence. High-quality analysis found that CBT combined with biofeedback or relaxation was among the most effective treatments for reducing chronic TMJ pain. Behavioral approaches also improve anxiety, depression and jaw function when added to standard care, and are increasingly viewed as a central part of comprehensive TMJ care.

Putting It Together

• Treatment usually starts with the safest, reversible options: self-care, a soft diet, heat or cold, exercises, and stress and sleep strategies.

• Splints and short courses of medication are common additions.

• Injections, joint washout and keyhole surgery are considered when conservative care is not enough.

• Open surgery and joint replacement are reserved for severe or unresponsive cases.

• A combination of approaches, matched to the individual and reviewed over time, generally works best.
