A headache may seem unrelated to your teeth, but the teeth, jaw, and head share nerve pathways closely enough that a toothache, jaw pain, or other orofacial pain can sometimes appear as head pain instead. This does not mean every headache has a dental cause, but when headaches occur alongside tooth sensitivity, jaw soreness, or pain when chewing, a dental examination can help identify, or rule out, a connection.

Referred Pain and the Trigeminal Nerve
Referred pain occurs when pain originating in one area is perceived somewhere else. The trigeminal nerve carries sensory information from large areas of the face, including the teeth and jaw, so inflammation around a tooth can sometimes register as facial pain, ear pain, or a diffuse headache rather than a localized toothache. The reverse is also true: jaw or tooth pain does not automatically mean a dental problem is responsible, since migraine, tension headache, sinus pressure, dizziness, and other conditions can produce overlapping symptoms.
Tooth Decay, Dental Infection, and Cracked Teeth
A small cavity may cause few symptoms, but tooth decay reaching the tooth pulp can trigger persistent or radiating pain. A dental abscess or gum infection linked to gingivitis or periodontitis can also cause facial pain and calls for emergency dental care, particularly alongside facial swelling, fever, or difficulty swallowing. A cracked tooth, other tooth damage, or a bite alignment problem can add stress to the jaw muscles, and good oral hygiene reduces the risk of the tooth decay and gum disease behind many of these symptoms.
Bruxism, Clenching, and TMJ Disorders
Teeth grinding and clenching, especially during sleep, can leave jaw muscles working for hours when they should rest, producing sore teeth, jaw pain, or a headache most noticeable on waking. The temporomandibular joint connects the lower jaw to the skull and works every time you speak, chew, or yawn, and TMJ disorders can involve the joint, the surrounding muscles, or both, with symptoms including jaw or temple pain, clicking, and headaches. A dentist evaluating these symptoms may recommend a custom night guard or bite equilibration depending on the findings of a dental examination.
When to Seek Care
If headaches repeatedly occur alongside tooth sensitivity, pain when biting, swollen or bleeding gums, jaw tenderness, or discomfort after chewing or waking, schedule a dental examination. A dentist can check for decay, dental infection, cracked teeth, gum disease, and jaw-related conditions, and may recommend dental restoration, a night guard, or bite equilibration.
Facial swelling, fever, difficulty swallowing, or rapidly worsening pain calls for emergency dental care, while a sudden severe headache with weakness, confusion, or vision changes needs urgent medical evaluation.
