Yes, teeth grinding can cause migraines.
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 and migraines, 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 muscle tension in the head and neck. This tension can trigger migraines in some people.
If you are experiencing migraines and think they may be related to 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 your teeth and jaw, so it is important to address it as soon as possible.
