The temporomandibular joints are the two joints that connect your lower jaw to your skull. When these joints, the surrounding muscles, or the bite are not functioning as they should, the effects can extend well beyond the mouth.
Jaw pain and clicking, persistent headaches, neck and shoulder tension, disrupted sleep, and teeth grinding are all common presentations of TMD – and they are also, frequently, signs that the airway is under stress during sleep.
This overlap is significant. Bruxism – the grinding or clenching of teeth – is widely understood as a stress response, but it is increasingly recognised as a sign of sleep-disordered breathing. The jaw clenches as the body attempts to maintain an open airway.
