Smile confidently in the clouds- understand why teeth hurt when you fly and how to prevent it!
Flying should be exciting—whether you’re off on vacation or heading to an important meeting. But for some travelers, that ascent into the clouds comes with an unexpected and painful surprise: tooth pain during flights.
If you’ve ever experienced sharp or aching discomfort in your teeth while flying, you’re not imagining it. This condition is real and even has a name—aerodontalgia. Let’s dive into why this happens, what it could mean about your dental health, and what you can do to stay pain-free at 30,000 feet.
Aerodontalgia is the technical term for tooth pain that occurs during altitude changes—such as when flying in an airplane or even scuba diving. According to the Federal Aviation Administration (FAA) and dental health professionals, it’s a condition triggered by pressure changes in the environment, which can impact gas pockets trapped inside your teeth.
While not dangerous, aerodontalgia is often a sign of an underlying dental issue that may require professional care.
Why Do Teeth Hurt During Flights?
During takeoff and landing, the cabin pressure changes rapidly. Our body generally adjusts to this without issue—but your teeth aren’t always so adaptable, especially if there’s a problem like a cavity or a poorly sealed filling.
Your teeth contain tiny air pockets within the pulp and dentin. When external pressure changes, these internal air pockets expand or contract. If your tooth has a gap or defect (even a small one), this pressure shift can trigger discomfort or even sharp pain.
Common Dental Issues That Cause In-Flight Pain
If your teeth hurt when you fly, the following dental issues may be to blame:
Tooth Decay (Cavities): Decayed areas may allow air to become trapped and sensitive to pressure changes.
Leaky Fillings: A filling that isn’t sealed well can trap air or bacteria, which may expand at high altitudes.
Dental Abscess or Infection: An abscess contains gas-producing bacteria that can react to altitude.
Cracked Tooth: Even tiny cracks allow pressure to affect the inner parts of your tooth.
Recent Dental Work: Teeth that were recently treated may still be sensitive, especially if nerve tissue is inflamed.
How Cabin Pressure Affects Your Teeth
The cabin of a commercial aircraft is pressurized to mimic conditions at about 6,000–8,000 feet above sea level. That’s a big shift—especially compared to ground-level pressure your body is used to.
According to the Centers for Disease Control and Prevention (CDC), changes in atmospheric pressure can affect more than just your ears—they can impact sinuses, joints, and even dental structures.
If your tooth contains air pockets or trapped gas due to decay or restoration, this change in altitude can create expansion inside the tooth, pushing against the sensitive nerve tissue and causing pain.
What You Can Do to Prevent Airplane Tooth Pain
The best way to avoid in-flight tooth pain is by being proactive about your dental health. Here are practical steps you can take:
Get Regular Dental Checkups: Make sure your teeth are free from decay, cracks, and old fillings that may fail.
Schedule Cleanings Before Travel: A professional cleaning can reveal potential issues before they become painful.
Treat Sensitivity Early: If you already notice sensitivity to cold or pressure, have it evaluated before your flight.
Avoid Flying After Major Dental Work: Wait at least 48 hours after procedures like root canals or extractions unless advised otherwise by your dentist.
Use Desensitizing Toothpaste: This can reduce discomfort if your teeth are mildly sensitive.
Stay Hydrated: Dry air in airplanes can worsen dental and sinus issues.
Helpful Table: Symptoms, Causes & What to Do
| Symptom | Possible Cause | Recommended Action |
|---|---|---|
| Sharp pain during takeoff | Leaky filling or cavity | See a dentist for evaluation |
| Dull ache in upper molars | Sinus pressure or infection | Rule out sinus issues; consult both dentist & doctor |
| Pain after recent dental work | Inflammation or pressure sensitivity | Inform your dentist before flying |
| Tingling or pressure sensation | Cracked tooth or crown issue | Dental x-rays to confirm |
When to See a Dentist
If you regularly experience pain during flights or notice lingering discomfort after traveling, don’t ignore it. These may be signs of:
- An untreated cavity
- A cracked filling or crown
- Early stages of infection
- Problems with dental restorations
Prompt evaluation can save you from bigger dental procedures (and help you enjoy your flights pain-free).
