Wildfire Season & Your Mouth—What Milpitas Families Can Do

Every late summer and fall, Bay Area air quality can swing from “good” to “unhealthy” in a day. You already check AQI for outdoor plans—but wildfire smoke and very dry air can also affect your mouth. If you live or work in Milpitas, San Jose, Fremont, Union City, Mountain View, Sunnyvale, or Alviso, here’s how to protect your oral health through smoke season.

How smoke and dry air affect your mouth

• Dry mouth (xerostomia): When air is smoky, many people mouth-breathe more—saliva drops, so your mouth doesn’t naturally rinse acids and food as well. Persistent dry mouth is linked to higher risk of tooth decay and fungal infections because saliva helps keep harmful germs in check.
• Irritation: Fine particles from wildfire smoke can inflame the lining of your mouth and throat; sensitive folks may notice soreness or canker-sore flare-ups during bad AQI stretches. Public-health guidance during wildfire events emphasizes limiting smoke exposure to reduce these effects.

Practical steps on poor-AQI days

• Hydrate on a schedule. Sip water frequently; add xylitol gum or mints to stimulate saliva if your mouth feels parched.
• Switch to a fluoride + sensitivity routine. Fluoride strengthens enamel; potassium-nitrate formulas can calm reactive nerves when you’ve been mouth-breathing more at night.
• Improve indoor air. Keep windows closed, run HVAC on recirculate, and use a portable HEPA air cleaner or set up a “clean room” at home; avoid indoor pollution sources like candles and frying during smoke events.
• Use a humidifier (and clean it). Restoring moisture helps your mouth and sinuses; follow the unit’s cleaning instructions to prevent mold. Guidance on maintaining cleaner indoor air during wildfire smoke supports these steps.
• If you must go outside, wear a proper respirator. A well-fitting NIOSH-approved N95 can reduce inhaled particulates far better than cloth or surgical masks during smoky conditions.
• Nightguard wearers: rinse more. Stress can raise clenching/grinding—clean your guard daily and consider a soothing fluoride gel at bedtime.

When to call the dentist

• Mouth sores or irritation that don’t improve in 10–14 days
• A “cotton-mouth” feeling that persists despite hydration and saliva products
• New bleeding gums or a lingering bad taste
• Tooth sensitivity that spikes during a smoke stretch

Kid-friendly tips

• Pack water bottles and (age-appropriate) xylitol gum for after-school activities.
• If AQI is poor, shift vigorous play indoors and encourage nose breathing.
• Keep toothbrushes rinsed and replace more often during smoky months.
