I usually grind my teeth severely, so I often felt stiff and tired in my jaw when I woke up in the morning. At times, it even felt like a headache, so I consulted a dentist and decided to get jaw Botox. The procedure was simpler than I expected and finished quickly in just a few minutes. The pain during the injection was not particularly burdensome either. I felt a slight stiffness for about a day after the procedure, but it did not interfere with my daily life at all. After about two weeks, the stiffness in my jaw in the mornings decreased significantly, and my habit of clenching my teeth seems to have eased a bit as well. My jaw muscles feel more relaxed than before, so I think this could be helpful for anyone struggling with teeth grinding.
