What is the direct answer?
Sinus inflammation can cause pressure in upper back teeth, but a visible localized gum swelling needs dental assessment.
What does this question mean?
The maxillary sinus sits above many upper premolar and molar roots; congestion causes diffuse pressure, while a gum boil or tooth-specific biting pain suggests dental disease.
What can you do next?
Record nasal congestion, facial pressure, one-sided symptoms, and the exact tooth involved. Do not assume sinusitis explains a dental lump.
When should you seek dental care?
Seek prompt care for pus, fever, facial swelling, or worsening pain; breathing or swallowing difficulty is an emergency.
What should you ask the dentist?
Ask about cold testing, gum-pocket measurements, dental imaging, and whether medical sinus assessment is also needed.
