Teeth grinding and snoring can sometimes happen together while you sleep. This may be caused by stress, anxiety, poor sleep, a blocked nose, your sleep position, jaw issues, or breathing problems at night. Grinding can slowly harm your teeth and jaw, and snoring can disrupt your sleep, leaving you tired during the day. For some people, these problems are linked to sleep apnea, a condition where breathing briefly stops during sleep. You can try improving your sleep habits, lowering stress, avoiding alcohol or heavy meals before bed, and sleeping on your side to help reduce snoring. Dentists often suggest using a night guard or mouth guard to protect your teeth from grinding. Keeping a healthy weight, exercising regularly, and treating nasal allergies or blockages can also help you sleep better. If you have loud snoring, wake up choking, get morning headaches, have jaw pain, feel sleepy during the day, or notice damaged teeth, talk to your doctor.
