Do you grind your teeth at night without realizing it? This habit is called bruxism; when you unconsciously clench or grind your teeth, often during sleep. While it may seem harmless, over time it can cause tooth damage or sensitivity, jaw pain and headaches, and poor sleep quality. Stress, anxiety, misaligned teeth, or even certain medications can trigger it. Tips to protect your teeth: * Use a night guard if advised by your dentist * Manage stress with relaxation techniques * Avoid caffeine or alcohol before bed
