Is it common to have lockjaw after 2 weeks of wisdom teeth extraction?

Not uncommon: Go back to the dentist who should check you out. This is a complication for which the dentist isresponsible and he must treat the problem. Do not try to be your own dentist and look for answers on the intertnet. Go back and see what the dentist has to say and what can be done to help you.

Possible: It is possible to have muscle or TMJ soreness for several weeks following extractions that would make it difficult to open your jaw. It is also possible that there could be infection. You need to go back to the person who removed your teeth for a follow up if this is happening.
