Appointment with the dentist

This is about 2 months earlier than scheduled. However, he is complaining of headache and is pointing bilaterally to his TMJ area - which feels like the area that would be impacted by the new teeth coming in .. but I cant stand the thought that it could be from the decayed premolar. My lovely dentist gave me an appointment today so we will go to have him take a look at L's teeth and perhaps take an xray ...
