As we age, protecting our teeth becomes even more important. Teeth grinding, also called bruxism, can happen during sleep or even while you’re awake, often without you realizing it. It may be linked to stress, certain medications, sleep disorders, or natural changes in your bite over time. Grinding can cause headaches, jaw pain, worn and cracked teeth, as well as damage to existing crowns, bridges and implants. The good news is that your dentist can spot the signs early and recommend simple treatments, such as a custom night guard or other solutions, to help protect your smile and keep you comfortable.
