Is it true that a sinus infection causes toothache in the upper teeth?

Yes. A reference article on toothache states that maxillary sinusitis can cause pain in the upper back teeth, and that acute or chronic maxillary sinusitis can be perceived as maxillary toothache. This directly supports the claim that a sinus infection causes toothache in the upper teeth.
