Please help! i have a locked jaw, what should i do?

Try this: Locked jaw, a slippage of the mandible and maxilla so that cartilage gets in the way of motion, is painful and distressing. Try this trick: Open the jaw as wide as possible and then very slow move the jaw to the left and then to the right. This will commonly overcome the blockage, normalizing the joint . If this fails see your dentist or ENT specialist for a medical correction.
