Hello,
It is common for the jaw muscles to get into a spasm due to the spread of infection along the facial planes causing inability to open the mouth.You need to take a course of muscle relaxants with antibiotics and pain killers.Get rid of the infected tooth at the earliest.Dr Suman Makam,Dental Arts,Jayanagar,Bangalore.
