1 Temporomandibular Disorder (TMJ): A joint disorder that deals with the jaw joint located in front of the ear and the muscles surrounding it. It is a condition mostly treated by the dentist, as it may lead to toothaches.

TMJ disorder can cause headaches, mostly described as aching pain beginning near the ear and moving toward the jaw, neck, or temple region.

2. Trigeminal Neuralgia: The disorder that irritates the trigeminal nerve results in the formation of a disorder known as Trigeminal Neuralgia. In this condition, there is an excruciating shock-like facial pain on one side of the face.

In most cases, the pain is felt in both the upper and the lower parts of the jaw, which is one of the reasons why people visit their dentist initially to understand whether they are suffering from an abscessed tooth.

During this process, it is quite normal that the patient has to go through the root canal and extraction operation before they receive a diagnosis of trigeminal neuralgia3.
