It sounds like you may be experiencing a condition called bruxism, which is the grinding or clenching of teeth outside of chewing or swallowing. This can cause issues such as premature tooth wear, headaches, jaw pain, and joint discomfort. It is recommended to consult your dentist to determine the appropriate treatment, which may include custom occlusal splints to reduce tooth wear and alleviate jaw pain. Managing the cause of teeth clenching, such as stress, through relaxation techniques like meditation, breathing exercises, and cognitive restructuring, can also help reduce jaw pain. It's important to address both the physical symptoms and underlying stress to find relief from your jaw discomfort.
