One of the main reasons of a severe headache is a prolonged toothache. Toothaches are extremely painful and can prevent you from enjoying your food. It becomes difficult to speak if toothache is unbearable.
Causes of Toothache:
Tooth fracture resulting from an accident.
A painful infection at the root of your teeth or your gums. This is known as tooth abscess.
Chewing gum continuously and grinding the teeth.
How does toothache cause headache?
Sometimes, a tooth becomes very inflamed and since the nerve endings are connected to the brain, this, in turn makes the pain travel to different parts of your head. Generally, people with bad cavities or caries have major headaches and migraines.
The inside of a tooth consists of a pulp. This pulp can get infected. If this tooth happens to lie in the upper jaw, then the pain is transferred to the head which can cause a severe headache.
Headaches can also be caused by TMJD (Temporomandibular joint dysfunction). This usually occurs spreading from the face, jawline and neck right up to the head. In extreme cases, the jaws might be locked up and it makes clicking or grinding noises. Misalignment of the teeth can be a cause by TMJD which in turn affects the head greatly.
