Frequently asked questions
Can a sinus infection cause pain in my gums?
Yes, sinus infections can cause gum pain. The maxillary sinuses sit close to upper molar roots, and inflammation presses on nerves that also serve your gums. This referred pain makes your gums feel tender and sore, even though the infection is in your sinuses. About 10–20% of sinusitis patients report gum discomfort.
How long does sinus tooth pain last?
Sinus tooth pain typically lasts 7–10 days with proper treatment. If you use decongestants, saline rinses, and antibiotics if needed, the pain usually resolves as the sinus infection clears. If pain persists beyond 10 days, see a doctor to rule out other causes.
What does sinus tooth pain feel like?
Sinus tooth pain feels like a dull, constant ache or pressure in your upper molars and premolars. It often affects multiple teeth on both sides of your mouth. The pain worsens when you bend forward or move your head suddenly. Unlike dental pain, it does not react to hot or cold foods.
Can sinus infection cause pain in lower teeth?
Sinus infections rarely cause pain in lower teeth. The maxillary sinuses are located above the upper molars, so pressure affects only upper teeth. If you have lower tooth pain, it is more likely a dental problem like a cavity or abscess. See your dentist for an evaluation.
How do I know if my tooth pain is from sinus or dental infection?
Use the tap test and head tilt test. If multiple upper teeth ache equally when tapped, and pain worsens when you bend forward, it is likely sinus-related. Dental pain is sharp, localized to one tooth, and triggered by hot or cold. Sinus pain also comes with nasal congestion and facial pressure.
Will antibiotics help sinus tooth pain?
Antibiotics help only if your sinus infection is bacterial. About 90% of sinus infections are viral, so antibiotics do not work. Your doctor can determine if bacteria are the cause based on symptoms lasting more than 10 days or a fever. For viral sinusitis, decongestants and home remedies are more effective.
Can sinus infection cause gum swelling?
Yes, sinus infections can cause gum swelling. The inflammation from your sinuses can spread to nearby gum tissue, making it red and tender. Post-nasal drip can also irritate your gums. However, gum swelling from a sinus infection is usually mild and affects multiple areas, not just one tooth.
