Ringing in the ears and a sore, clicking jaw turn up in the same people much more often than chance would explain. What research cannot yet tell us is whether the jaw problem causes the tinnitus, the tinnitus leads to jaw problems, or something else drives both. That uncertainty shapes the sensible order of care: have your ears and hearing checked first, consider a jaw assessment alongside it, and be wary of any plan that promises to silence tinnitus by permanently changing your teeth.
The jaw joint is the ear's closest neighbour
Place a fingertip just in front of your ear and open your mouth, and you can feel the temporomandibular joint move. It sits directly in front of the ear canal, separated from it by only a thin plate of bone.
The two areas also share wiring. Branches of the trigeminal nerve supply the jaw joint and chewing muscles as well as parts of the ear, including a small muscle attached to the middle ear and the muscle that helps open the eustachian tube. When one nerve carries signals from neighbouring structures, the brain can struggle to tell them apart. The large chewing muscles also sit right beside the ear, so tension or soreness in them is easily felt as an ear problem. Our article on whether a tooth can cause ear pain explains this kind of referred sensation.
Anatomy explains why the two are hard to separate. It does not, by itself, show that one causes the other.
How often the two occur together
A 2026 systematic review and meta-analysis in BMC Oral Health by Alghamdi and colleagues pooled 34 observational studies. On average, about 32% of people with a temporomandibular disorder reported tinnitus, and about 63% of people with tinnitus had signs of a temporomandibular disorder. In studies with comparison groups, a jaw disorder diagnosis was linked with roughly four times the odds of tinnitus.
Tinnitus is not the only ear symptom involved. An earlier meta-analysis by Porto De Toledo and colleagues, published in Clinical Oral Investigations in 2017, found that a feeling of fullness in the ear was the most commonly reported ear symptom in adults with temporomandibular disorders, followed by ear pain and tinnitus.
The authors of the 2026 review were careful about what these numbers mean. All of the included studies were observational, many relied on people reporting their own tinnitus, results varied widely between studies, and the design cannot show which problem came first.
Three explanations that fit the evidence
The jaw may contribute to the tinnitus, through muscle tension, joint inflammation or shared nerve pathways. The reverse is also possible: living with distressing tinnitus can disturb sleep and raise stress, which commonly increases clenching and jaw pain. A third possibility is that a shared factor, such as stress, poor sleep or a general sensitivity to pain and bodily sensations, drives both at once.
For any one person, more than one of these may be at play. That is why a confident claim that your jaw is definitely causing your tinnitus goes further than the evidence supports.
Start with the ears
Tinnitus has many causes that have nothing to do with the jaw, including age-related and noise-related hearing loss, earwax, middle ear problems and some medicines. A small number of causes need prompt medical attention. See your GP, and ask about a hearing assessment with an audiologist, particularly if:
- the tinnitus started suddenly or is in one ear only
- it pulses in time with your heartbeat
- it comes with hearing loss, dizziness or a sense of imbalance
- you have had significant noise exposure through work or hobbies
A jaw assessment is a useful addition to this, not a replacement for it.
Signs the jaw may be involved
Some features make jaw involvement more plausible. Your ear symptoms may change when you open, close or move your jaw, or when you press on the muscles of the face or neck; this pattern is sometimes called somatosensory tinnitus. You may also have jaw pain, clicking, catching or limited opening on the same side, wake with a tight or tired jaw, or have teeth showing wear or new sensitivity from clenching or grinding. Symptoms that flare after a stressful week or a lot of chewing also point towards the muscles. Our guide to jaw joint pain covers the wider picture.
What a jaw assessment looks for
A useful assessment starts with your story: when symptoms began, what eases or worsens them, if you clench or grind, how you are sleeping and what else is happening in your life. The examination then measures how wide you can open, watches the path the jaw follows, listens and feels for joint noises, and checks the jaw and neck muscles for tenderness. The teeth are examined for wear, cracks and other signs of heavy loading.
Scans are not needed for most jaw disorders, which are mainly muscular. Imaging may be discussed if a problem within the joint itself is suspected. A good assessment does not jump straight to changing your bite.
Reversible care comes first
For most temporomandibular disorders, first-line care is simple and can be stopped at any time. During a flare, giving the jaw a rest helps: softer foods, smaller mouthfuls, and avoiding gum, very chewy foods and wide yawns. A warm compress over the sore muscles can ease tension. Many people clench during the day without realising, often while concentrating, driving or looking at a phone; learning to notice it and rest the jaw with the lips together and teeth slightly apart can help over a few weeks. A physiotherapist experienced with jaw and neck problems can provide exercises and hands-on treatment.
If you grind at night, a custom occlusal splint may protect the teeth and reduce the load on the muscles. Clenching often has everyday triggers, which our articles on weightlifting and clenching, gaming and jaw clenching and exam stress and grinding explore. Improving sleep and managing stress often help more than anything done to the teeth.
Permanent changes, such as grinding teeth down to adjust the bite or crowning several teeth to alter how they meet, are not first-line treatment for jaw disorders and have no established role in treating tinnitus. Given that a causal link has not been shown, altering healthy teeth in the hope of quietening the ears is a poor trade. A second opinion is reasonable if a plan heads that way quickly.
What jaw treatment can and cannot do for tinnitus
Some people find their tinnitus becomes less noticeable or less distressing as jaw symptoms settle. Others find their jaw pain improves while the ringing stays the same. It is safest to expect that any change in tinnitus may be partial, and to treat a genuine jaw problem for its own sake, because pain, limited opening, headaches and tooth wear are worth addressing regardless. People also often ask about braces and jaw problems; our article on orthodontic treatment and TMJ looks at that question. If cost is a concern, our guide to dental costs without private health insurance may help, and it is worth checking if your health fund contributes to splints.
Questions about jaw problems and tinnitus
Will a night guard stop my ears ringing?
It may help if clenching or grinding is part of the picture, but there is no basis for expecting it to reliably stop tinnitus. It is worth considering if you grind, with any change in the ringing seen as a possible extra.
Should I see a dentist or my GP first?
Your GP, especially for new tinnitus, tinnitus in one ear, pulsing tinnitus, or tinnitus with hearing loss or dizziness. Once the ears have been assessed, a jaw examination is a reasonable next step if you also have jaw symptoms.
Why do both get worse when I am stressed?
Stress often increases clenching, disrupts sleep and makes people more aware of internal sounds and sensations. That shared pathway may be one reason the two are so often reported together.
Booking a jaw assessment
If you have ringing in the ears, start with your GP so the ear side is assessed properly. If you also have jaw pain, clicking, limited opening or signs of clenching, our dentists can examine your jaw joints, muscles and teeth and talk through reversible options, along with a realistic view of what jaw treatment may or may not do for your ears.
