What Causes Teeth Grinding?

Teeth grinding can have many triggers, but some of the most common causes include:

• Stress and Anxiety – Emotional tension is a leading cause of nighttime bruxism.

• Sleep Disorders – Conditions like sleep apnea can increase nighttime grinding.

• Bite Misalignment – When teeth don’t fit together properly, your jaw muscles may clench unconsciously.

• Lifestyle Habits – Excess caffeine, alcohol, or smoking can increase muscle tension and grinding frequency.

Over time, this constant pressure can wear down enamel and strain the supporting tissues of your teeth—including your gums.
