Headaches and tooth pains are interconnected by the craniocervical (skull and neck) and the orofacial (mouth, jaws, and face) systems that can lead to intense pain due to their anatomical proximity.
Headaches and toothaches share the same nerve called the trigeminal nerve. The trigeminal nerve is the largest sensory nerve in the head that applies to the external of the face, scalp, teeth, jaws, and the majority of your intraoral structures.
When you feel pressure due to a teeth inflammation, the nerve is signaled to relay the pain to other areas of your craniocervical. If the pain intensifies, with the tooth pain chronically throbbing and lingering, it will positively activate drag to other nerve branches to form vast clusters of excruciating headaches.
One of the reflexive conditions to cause pain is muscle tightening and jaw clenching that cause significant discomfort. For example, when you clench your teeth, this contracts the muscle from your neck muscles that trigger tension to create jaw muscle pain leading to a headache.
Sometimes it is difficult for primary doctors to determine the reasons for the headache to diagnose the cause. Dentists will have the skills needed to diagnose and recognize the cause of orofacial pain.
Persistent headaches that stem from chronic toothaches should be consulted by a dental professional. The dentist is qualified and fully equipped to handle your pain and help treat the problem efficiently.
