Yes, teeth grinding can cause headaches.
When you grind your teeth, you are applying a significant amount of force on your teeth, which can cause the muscles in your jaw to become strained and sore. This can lead to headaches, as the muscles in your jaw are connected to the muscles in your head.
Additionally, grinding your teeth can cause the muscles in your jaw to contract and relax repeatedly, which can lead to tension headaches.
If you are experiencing teeth grinding, it is important to talk to your dentist or healthcare provider to determine the cause and find an appropriate treatment.
Teeth grinding can cause long-term damage to the teeth and jaw, so it is important to address it as soon as possible.
