Why Your Teeth May Hurt During Airplane Flights

Jan 12

Ever felt a sudden, sharp toothache mid-flight? You’re not alone. Airplane tooth pain—also known as barodontalgia—is a surprisingly common yet rarely discussed issue. The changes in cabin pressure at high altitudes can impact not just your ears or sinuses, but also your teeth—especially if you have untreated cavities, fillings, or dental infections. This article explores the science behind altitude-related tooth pain, identifies who’s most at risk, and offers expert-backed tips to protect your oral health before, during, and after air travel. Plus, discover how smart brushing routines can reduce the likelihood of in-flight surprises.

✈️ What Is Barodontalgia?

Barodontalgia is a term used to describe dental pain caused by changes in atmospheric pressure—most often during flying, diving, or hiking at high altitudes.

How It Happens:

 • During takeoff and landing, the air pressure in airplane cabins drops or rises rapidly.
 • If there’s trapped air inside a tooth (due to decay, cavities, or poorly sealed fillings), it can expand or contract.
 • This expansion puts pressure on the tooth’s nerves, triggering sharp pain or discomfort.

⚠️ Who Is at Risk?

You’re more likely to experience airplane tooth pain if you have:

 • Untreated cavities or dental decay
 • Cracked or leaky fillings
 • Infected root canals
 • Loose crowns or bridges
 • Recent dental work (within the last 48 hours)

Even seemingly minor issues can flare up at 35,000 feet.

😬 Common Symptoms of In-Flight Tooth Pain

 • Sudden toothache during takeoff or descent
 • Sharp pressure pain around a specific tooth
 • Sensitivity in the upper molars or sinus area
 • Persistent ache during the flight
 • Pain that disappears after landing (but may return next time you fly)

🛡️ How to Prevent Tooth Pain While Flying

🦷 Schedule a Checkup Before You Travel

Get any cavities, infections, or loose restorations fixed ahead of time. Dentists can spot issues that might worsen with air pressure changes.

💧 Stay Hydrated

Cabin air is extremely dry, which can dry out your mouth and increase sensitivity. Drink water regularly and avoid sugary or acidic drinks before and during the flight.

🧠 Use a Smart Toothbrush Daily

Consistent, effective brushing helps prevent decay and cracks that may cause in-flight pain. Smart brushes like BrushO:

 • Ensure even pressure and coverage
 • Track your brushing habits via app
 • Identify areas of potential neglect before they become problems

😮‍💨 Avoid Flying Immediately After Dental Work

Wait at least 48–72 hours after procedures like fillings, crowns, or root canals before flying to allow dental materials to set and stabilize.

✨ What to Do If You Experience Tooth Pain Mid-Flight

 • Chew sugar-free gum: It can help equalize pressure and stimulate saliva.
 • Rinse with water: If possible, rinse with clean water to ease discomfort.
 • Take mild pain relief: Over-the-counter painkillers like ibuprofen can help temporarily.
 • Schedule a dental visit after landing: Recurring in-flight pain is a sign of an underlying issue that needs attention.

🌍 Protecting Your Smile While You Travel

Travel can be stressful, but toothaches shouldn’t be part of your journey. Regular smart brushing with BrushO, staying hydrated, and being proactive about oral care before boarding are the best ways to keep your teeth pain-free while flying. Think of your next flight as a reminder—not a risk—for great dental hygiene.
