What Are Headaches ?
People experience headaches now and then. It is the most common ailment experienced worldwide. It is usually described as a band of pressure or pain or both, affecting certain areas of head like the forehead or temples or sometimes the whole head. This pain can be dull and constant or pulsating and intermittent. Pain can be on one side of head or on both sides.
However, a headache is not a disease in itself. It is just a symptom caused by an underlying condition. The majority of these underlying disorders are mild conditions that can be treated with primary care.
Types Of Headaches.
Headaches are generally classified into two types as follows :
- Primary headaches: These include migraines, cluster headaches, and tension headaches.
- Secondary headaches: These headaches occur after a head injury or as a result of taking too many pills.
Amongst this, tension headaches are the ordinary headaches which we experience in our day to day life.
Now, teeth grinding causes tension headache. But to understand this relation, we need to first understand how tension headaches usually happen.
How Do Tension Headaches Occur ?
Tension headaches can be caused by multiple factors.
The most common cause is stress.
Besides stress, they can also be caused by increased muscular activity. So, when a muscle of the face or near the head region is stretched beyond its capacity or is used constantly for very long duration, it can cause tension headaches.
What Is The Relationship Between Headache And Bruxism ?
Bruxism or teeth grinding causes repeated contraction of jaw muscles.
Muscles like the temporalis muscle, which is located in the temple region on both sides of head and the frontalis muscle, which lies in the forehead region, are commonly affected in bruxism. Constant grinding of teeth leads to over-usage of this muscles causing muscle soreness and ultimately tension headaches.
A condition called Lock jaw or Trismus, wherein all the jaw muscles stay in a contracted position can also cause headache and bruxism. In this case, also expect pain in the neck and in the ear.
What Is The Relationship Between Headache And Sleep Bruxism ?
Sleep Bruxism is caused by microarousals from sleep. When you grind your teeth while sleeping, muscles are contracted causing muscular fatigue. This ultimately causes tension headaches.
