Probably an issue referred to as a TMJ closed lock. This is not dangerous and usually is a result of inflammation resulting from chronic bruxism (tooth grinding) while you are asleep at night. It will likely resolve on it's own, but may require a visit to an oral surgeon. You'll want to consult with your dentist for splint therapy to avoid this in the future and to protect your joints and teeth.

A locked jaw indicates the joint is either displaced or dislocated and it usually will not fix itself. Conserative means (reversible) like a splint and physical therapy are good to find a better functional position. If found, this position can be supported by a bite that maintaines this more stable relationship. Do reversibel diagnostics first to find the best functionalposition. Get help now.
