What are the causes of teeth grinding during sleep?

The causes of teeth grinding during sleep may be related to stress, dental occlusion issues, or lifestyle habits. Mental stress and anxiety are common triggers that may lead to nocturnal teeth grinding. Additionally, if the teeth are misaligned or the occlusion relationship is abnormal, teeth grinding may also occur. Some individuals who excessively chew hard objects during the day or maintain tense facial muscle states for prolonged periods are also prone to experience teeth grinding during sleep. In a few cases, teeth grinding may be associated with certain medical conditions, such as gastrointestinal problems or nervous system disorders. Understanding the specific cause is helpful for implementing targeted measures to alleviate symptoms.

To improve teeth grinding during sleep, it is recommended to start by adjusting lifestyle habits. Try to reduce stress, maintain regular sleep patterns, and attempt relaxation techniques or meditation to relieve anxiety. Avoiding caffeinated beverages and consuming excessive amounts of stimulating foods before bedtime can also help reduce the likelihood of teeth grinding. If you suspect that dental occlusion problems are the primary cause, consult a dentist to evaluate whether wearing a mouthguard or undergoing orthodontic treatment is necessary. Long-term teeth grinding may damage the teeth and temporomandibular joints; therefore, if symptoms persist or worsen, timely medical attention is recommended.
