headaches and jaw pain months after fillings

I've had 6 fillings (4 replacements of old fillings and 2 new ones) done about 2 months ago. 2 fillings where in the upper right teeth, 3 in the lower left and one in the upper left. Since I have had the fillings done I have been experiencing some jaw pain, mostly in my lower jaw on the left side but also on the right side (though no fillings where done on the lower right side). I have also been having moderate headaches mostly in the temples, above the eyebrows and ears. Ear infection and sinusitis have been ruled out by my GP. I have NO pain in any of my teeth. Could the head and jaw pain be somehow related to the dental work I've had done? does anyone have any idea what could be causing the pain?

Thanks
