Why does your teeth hurt if you don't get any sleep?

Teeth can hurt when you're sleep-deprived due to increased stress and tension, which may lead to teeth grinding or jaw clenching, known as bruxism. Lack of sleep can also exacerbate existing dental issues, making sensitivity and pain more pronounced. Additionally, insufficient rest can weaken the immune system, making it harder for your body to fight off infections that might contribute to dental discomfort.
