Temporomandibular Disorders (TMD): Symptoms, Diagnosis and Treatment

Overview

Temporomandibular disorders (TMDs) are a group of more than 30 conditions that cause pain and dysfunction in the jaw joint (the temporomandibular joint, or TMJ) and the muscles that move the jaw. They fall into three broad categories: disorders of the joint itself, including problems with the small disc inside it; disorders of the chewing muscles; and headaches associated with TMD.

TMD affects about 5% of adults in the United States and is twice as common in women as in men. In most cases the exact cause is not clear. Research suggests a combination of genes, psychological and life stressors, and how a person processes pain may all play a part, and injury to the joint can contribute. Notably, research does not support the common belief that a "bad bite" or orthodontic treatment such as braces causes TMD. TMD often occurs alongside other conditions, including headaches, back pain, sleep problems, irritable bowel syndrome, and fibromyalgia.

The encouraging part is that conservative, reversible approaches are the recommended starting point and help many people. It is also worth knowing that clicking or popping in the jaw without pain is common, considered normal, and does not need treatment.

Symptoms

Pain in the jaw joint or chewing muscles (the most common symptom)
Pain around the jaw, ear, and temple, sometimes spreading to the face or neck
Jaw stiffness or limited ability to open your mouth fully
Jaw locking open or closed
Painful clicking, popping, or grating when moving the jaw
Headaches
Ringing in the ears, hearing changes, or dizziness
A change in how your upper and lower teeth fit together

Diagnosis

Symptom and medical history review: there is no widely accepted standard test for TMD, so your description of pain, triggers, and jaw function is central
Physical exam: checking jaw movement, tenderness in the joint and chewing muscles, and any clicking or locking
Imaging: X-rays, MRI, or CT scans may be ordered in some cases to look at the joint and disc
Screening for related conditions: asking about headaches, sleep, and other pain conditions that often occur alongside TMD

A dentist or doctor typically evaluates TMD, with an orofacial pain specialist for persistent or complex cases, often after an initial visit with a primary care doctor.

Treatments

Self-care: soft foods, heat or cold packs, gentle jaw muscle massage, and avoiding gum, nail biting, wide yawning, and clenching
Over-the-counter pain relievers: NSAIDs such as ibuprofen for short-term relief
Physical therapy: including manual therapy for jaw muscles and joint mobility
Behavioral approaches: cognitive behavioral therapy, biofeedback, and relaxation or meditation to address stress and pain processing
Oral appliances: nightguards or splints worn in the mouth
Limited or mixed evidence: acupuncture and TENS have limited evidence; botulinum toxin (Botox) is not FDA approved for TMD and its effectiveness remains unclear
Procedures: arthrocentesis and arthroscopy may help some people with joint problems; open surgery and TMJ implants lack long-term research and are considered only after simpler treatments fail
Treatments to be cautious about: permanently changing your bite with crowns, tooth grinding, or orthodontics has insufficient evidence for TMD and can sometimes make things worse

Your Care Plan

A step-by-step guide to navigating your condition, from finding the right doctors to advocating for the care you deserve.

Step 1: Doctors to See

Start with: Your dentist or primary care doctor, who can examine your jaw and rule out other causes of facial or ear pain.

Then seek: An orofacial pain specialist (a dentist or doctor who focuses on jaw and facial pain), especially if self-care has not helped after a few weeks or your jaw locks.

Build your team:

Physical therapist: for jaw exercises and manual therapy
Psychologist: for cognitive behavioral therapy, biofeedback, or relaxation training
Primary care doctor: to coordinate care for related conditions like headaches, sleep problems, or fibromyalgia
Surgeon who specializes in TMDs: only if conservative treatment has failed and a procedure is being considered

Step 2: Advocate for Yourself

The most important thing to know about TMD is that reversible, conservative treatment comes first. If anyone recommends permanently reshaping your teeth, changing your bite, orthodontics, or surgery as a first step, ask about the benefits, risks, and alternatives, and consider a second opinion from an orofacial pain specialist. The National Institute of Dental and Craniofacial Research specifically advises caution with irreversible treatments. It is also worth mentioning any headaches, sleep problems, or other pain conditions, since TMD often travels with them and addressing the whole picture can help. Seek urgent care if you cannot eat or drink or your jaw will not open.

Step 3: Your Action Plan

Track your jaw pain for two weeks: when it happens, what triggers it (chewing, stress, waking up), and how wide you can open your mouth.
Notice habits like clenching, grinding, gum chewing, or nail biting and write them down.
Try conservative self-care: soft foods, heat or cold, gentle massage, and avoiding wide yawns.
See your dentist or doctor if pain persists, and describe any locking, headaches, or ear symptoms.
Ask whether physical therapy, an oral appliance, or cognitive behavioral therapy would help.
Before agreeing to any irreversible treatment, ask about evidence, risks, and alternatives, and get a second opinion.
Mention related conditions like headaches, sleep problems, or IBS so your care team can see the full picture.
