As a firefighter I do everything from fight grass fires, house fires, rubbish fires, car fires, anything that can catch on fire weâd be called for it. We go to medical calls, any time ambulances are called out we go to it. We do everything from heart attacks to small injuries to car wrecks.
I had a rear molar worked on 2 weeks ago, and now I can't open my jaw enough to place anything larger that my pincky finger into it. Went to the oral surgeon yesterday, he told me I had trismus, caused by a spasm in my muscle of the jaw due to the needle from the novacain. His suggestion to increase how far my mouth will open, start with 7 tongue depressors, insert between my teeth, and add a new one everyday until I can get 27 in there.
It may become difficult to open and close, and you may have stiffness upon opening and closing. This stiffness can also be caused by an injection. If it was your lower teeth that were prepared for the crown, then the lower injection can lead to a condition called trismus. Trismus is a muscle injury as a result of the injection path of the needle. Trismus symptoms are much like TMD symptoms. It might feel like your jaw muscle has a Charley horse.
