You might be having a condition called Lock jaw which is due to slippage of the Lower jaw from its socket. This occurs when you open your mouth very wide, as in yawning or laughing aloud. Try to avoid such situation. If not possible you need to take an opinion from a orthopaedic who deals with it or a maxillofacial surgeon.
