Do you often wake up with a headache, sore jaw, neck, or shoulder? You may grind your teeth during sleep. Teeth clenching, also called Bruxism, is a sleep-related movement disorder affecting 8 to 10 percent of adults in the US.

It is an involuntary action that could also be your body’s coping mechanism or response to stress or anxiety. But do you know what is it’s primary reason? Most people clench their teeth during the day from time to time, while others do it in their sleep. Is that also because of stress or anxiety, or is there something else we are missing out here?

What Causes Grinding Teeth?

The cause of bruxism is unique to every individual. While for some, it could be just a habit. For others, it could be due to psychological or physical conditions.

If we talk about daytime clenching, it’s mostly because of stress and anxiety. On the contrary, nighttime grinding could result from sleep apnea, hyperactivity, or a side effect of certain medications.

Some researchers also link smoking, the use of caffeine, tobacco, and drugs to bruxism.
