Don’t Let Fall Allergies Affect Your Smile: How Sinus Pressure Impacts Oral Health
Fall in Texas brings cooler air, colorful leaves — and for many, seasonal allergies. While sneezing and congestion are expected, one surprising symptom often catches people off guard: tooth pain.
At Ballard Family Dentistry, we often see patients who think they have a cavity or tooth infection, only to discover their discomfort is linked to sinus pressure. Here’s how fall allergies can affect your smile — and what you can do to keep your mouth healthy all season long.
How Sinus Pressure Can Cause Tooth Pain
Your maxillary sinuses sit just above your upper back teeth. When allergies or a sinus infection cause those spaces to fill with mucus or become inflamed, the pressure pushes down on the roots of those teeth.
That’s why allergy-related tooth pain:
-
Feels dull or achy, not sharp
-
Affects several upper teeth at once
-
Gets worse when you bend over or lie down
-
Comes and goes with allergy flare-ups
It’s not a cavity — it’s your sinuses! But since dental and sinus pain can feel similar, it’s always smart to get checked if you’re unsure.
How Allergies Impact Your Oral Health
Seasonal allergies can affect more than just your sinuses — they can also impact your mouth and gums.
Here’s how:
-
Mouth breathing: Congestion often causes you to breathe through your mouth, leading to dryness that increases cavity risk.
-
Dry mouth from antihistamines: Allergy medications can reduce saliva flow, making it easier for bacteria to thrive.
-
Postnasal drip: Constant drainage can irritate your throat and leave a sour taste, sometimes leading to bad breath.
Over time, these issues can increase your chances of tooth decay, gum irritation, and bad breath if not addressed properly.
Dental Tips for Allergy Season
To keep your mouth healthy (and comfortable) during fall allergy season, try these dentist-approved strategies:
-
Stay hydrated: Drink plenty of water to counteract dry mouth and help rinse away allergens.
-
Rinse with salt water: This can soothe your throat and clear nasal passages naturally.
-
Use a humidifier: Adding moisture to your home’s air helps prevent dry mouth while you sleep.
-
Keep your mouth clean: Brush twice a day and floss daily to remove allergens and bacteria buildup.
-
Change your toothbrush: After allergy season or illness, replace your brush to prevent reinfection.
-
Schedule a dental cleaning: A professional cleaning removes plaque buildup that can worsen allergy-related irritation.
When to Call Your Dentist
If your tooth pain:
-
Persists for more than a few days
-
Feels sharp, localized, or sensitive to hot/cold
-
Comes with swelling or fever
…it may not be sinus-related. Schedule a check-up at Ballard Family Dentistry — we’ll determine if your discomfort is due to allergies, infection, or another dental issue.
