If you suspect bone(s) broken during upper tooth extraction, which type of ct is appropriate, face, skull, or some other? is it worth the radiation if a person continue to have pain and headache?

Depends: Usually a dental x-ray can identify this, since you see the entire tooth when taken propperly (recall when the dentist shows you yours you see the whole tooth--root and all). There is much less radiation in an x-ray than in a ct, which is a series of closely-spaced x-rays. Talk to your dentist.

Please see a dentist: A standard x-ray should be adequate to check for fractures. You need to make sure there isn't an infection or bite issues. Tmj is also a possiblity. Please see a dentist.

Depends: If you suspect the maxillary alveolus is fractured traditional xray will reveal.These are common with extractions and usually heal with no treatment.If the maxilla is suspected (uncommon), traditional xray or cone beam cat scan

CBCT: You are better off with a cbct scan. We use the galileos cone beam computed tompgraphy. Very low radiation: about a week of normal back round radiation dose can see full skull in one 14 second scan.
