Dear Sandy, There is a slight possibility that the removal of braces could be the reason for your daughter's headaches. However, this may not be the only cause. Headaches can be caused by a number of things, some related to the mouth and jaw. For example, occlusion, bruxism, a TMJ-related problem, sinus congestion and other cranial abnormalities can also contribute to headaches.
Stress can even play a role.
A time frame of when the headaches come and go, how often they occur, and if they are triggered by certain stimuli may be helpful. He or she could also re-evaluate her bite to be sure it is in proper alignment and discuss possible TMJ symptoms. These symptoms might include soreness in the jaw area or difficulty closing or opening the mouth, in addition to the headaches. If consulting with your dentists doesn't reveal any problems with the oral or TMJ structures, I would pursue this further with your physician. You should not rely on this information as a substitute for personal medical attention, diagnosis or hands-on treatment.
