interested to know how do dental caries cause maxillary sinusitis?

Maxillary sinusitis: I'm not sure where you heard that but honestly, dental caries does not cause maxillary sinusitis. A sinusitis can mimic a tooth ache in certain teeth. An upper posterior infected tooth (from untreated cavities) can spread to the sinus. If still not answered, please restate your question or ask your own dentist regarding any issues you have.

Not uncommon: Tooth infection is usually caused by dental caries and its consequences. It is not uncommon that sinusitis results from untreated maxillary dental infection.
