Teeth grinding during sleep, medically referred to as bruxism or sleep-related tooth wear, may have various causes. It can be associated with mental stress and anxiety, as tension and stress can lead to muscle tightness, including that of the chewing muscles. Abnormal occlusion, such as misaligned teeth, may also trigger teeth grinding. Sleep disorders, such as sleep apnea, sometimes accompany bruxism. Certain medications and alcohol consumption may also affect normal nervous system function, leading to teeth grinding. To reduce the effects of bruxism, you may try the following methods:
1. Relaxation techniques: Practice deep breathing, yoga, or meditation before bedtime to reduce stress and anxiety.
2. Mouth guards: Wear a dentist-prescribed mouth guard at night to protect your teeth from wear.
3. Adjust lifestyle habits: Avoid consuming caffeine and alcohol in the evening, and ensure a good sleep environment.
4. Regular dental checkups: Visit your dentist regularly to monitor the condition of tooth wear.
If teeth grinding is severe or persists, seek medical attention promptly.
