Can white composite fillings cause jaw/face pain?

Yes: Composite fillings that are deep to the nerve or into the nerve can cause pain or jaw/facial pain. A filling that is too high (high bite), can also cause facial pain as well. Usually a very simple fix is feasible to stop pain for bite adjustments but deep fillings can be more involved to treat.

Possibly: Fillings can cause pain, whether it is composite (tooth colored) or alloy (silver) or even a type of crown. Pain could mean infection or irritation. Keep in mind that teeth hate fillings.The result in even the smallest filling can be some type of sensitivity to something cold or hot, the longivity indicating if it is reversible or not. However, pain is usually not associated with small filings.

Yes adj ASAP!!: A thick "high" filling of immediately light cured "white" composite restoration can create serious jaw and TMJ discomfort. In the least it can be annoying or create tooth sensitivity at the most it can cause TMJ issues and/or fracture the filled tooth and it's opposing tooth. While ones bite seems to adapt, it doesn't! a slight bite adjustment now can prevent significant pain latter.

Yes: Yes. See DDS for evaluation. Can be from inflammation of tooth, or high filling irritating TMJ.
