There are multiple dental conditions which could, at times, be responsible for not only tooth and mouth pain but migraines as well including:
Teeth Grinding
Teeth grinding, otherwise known as bruxism, is when patients grind their upper and lower teeth together, by involuntary clenching, grinding and gnashing their teeth together. Teeth grinding often occurs at night and can be caused because of increased stress and anxiety. The pressure and action of grinding your teeth at night can cause jaw pain and intense migraines.
Temporomandibular Joint Disorder
Temporomandibular joint disorder, otherwise known as TMJ or TMD is when the TMJ joint of your jaw can become inflamed, painful and sensitive and can lead to patients being unable to use that side of their mouth.
The temporomandibular joint is the two joints which connect your lower jaw to your skull, which slide and rotate in front of each ear when you move your mouth.
When properly aligned, the joints, paired with smooth muscle actions allow yawning, talking, chewing and eating to take place without any issues. If you have been grinding your teeth or have suffered from excessive strain or trauma to your neck your TMJ can become inflamed.
The built-up tension and inflammation can cause jaw joint problems (TMD) within the TMJ, leading to extreme migraines and possible tooth damage.
Toothache
One of the most known and common causes of pain and migraines can be toothache. When left untreated, tooth pain, which can be caused by untreated cavities, inflamed gums or other issues, can lead to painful migraines.
