Why Teeth Hurt or Throb During Flights and High-Altitude Travel

Usha Dental Clinic · Sector 15, Gurugram · Updated 2026-10-14

If you have ever felt a sudden toothache while taking off or landing, or noticed a tooth throbbing as your flight climbed in altitude, you are not imagining things. This is a real and fairly common condition called dental barotrauma, and it happens because of changes in air pressure acting on tiny pockets of trapped air or gas inside or around a tooth.

At Usha Dental Clinic in Sector 15, Gurugram, we see this come up often with patients who travel frequently for work or vacations. The good news is that it is usually preventable with a quick dental check before you fly.

What Causes Tooth Pain During Flights

Your teeth, sinuses, and the air in the cabin all respond to pressure changes. As a plane climbs, cabin pressure drops. If there is a small air pocket trapped inside a tooth, such as under a loose filling, in a cavity, near a cracked tooth, or within an infected or inflamed nerve, that trapped air expands. This expansion pushes against sensitive nerve tissue inside the tooth, causing sharp or throbbing pain.

The same thing can happen with sinus congestion. Your upper back teeth sit very close to your sinuses, so sinus pressure changes during a flight can sometimes feel exactly like tooth pain, even when the teeth themselves are healthy.

Common Dental Conditions That Make This Worse

• Untreated tooth decay or cavities with hidden air pockets
• Old or loose fillings that have gaps underneath
• Cracked or fractured teeth
• Recent dental work that has not fully settled or healed
• Infection or inflammation at the root tip (sometimes without obvious symptoms on the ground)
• Sinus congestion or a recent cold affecting the upper jaw

Why It Happens More at High Altitude or on Mountain Trips

It is not only flights. Driving up to hill stations or trekking at high altitude can trigger the same effect, since the principle is the same: lower outside air pressure causes trapped gas in a tooth to expand. People sometimes notice it on trips to places like Shimla, Manali, or Leh, not just on airplanes.

How to Prevent Dental Barotrauma Before You Travel

Most cases are preventable with a little planning, especially if you have upcoming air travel or a high-altitude trip.

• Get a dental check-up a week or two before travel, especially if you have had tooth sensitivity, a lingering ache, or an old filling that feels off
• Treat cavities and replace loose or old fillings before you fly
• Avoid scheduling major dental procedures, like root canals or extractions, right before a flight, since the area needs time to settle
• Manage sinus congestion or colds before travel, as decongestants taken shortly before flying may help some people
• Stay hydrated during the flight, since dry cabin air can make existing sensitivity feel worse

What to Do If Your Tooth Hurts While Flying

If pain starts mid-flight, there is not much you can do to stop the pressure change itself, but a few things can ease discomfort until you land.

1. Try swallowing, yawning, or gently chewing gum to help equalise pressure, similar to clearing your ears
2. Avoid very hot or very cold drinks, which can intensify tooth sensitivity
3. Breathe through your nose if sinus pressure seems to be the trigger
4. Note which tooth hurt and when, so you can describe it clearly to a dentist later

Pain from dental barotrauma usually fades once the plane reaches cruising altitude or after landing, since pressure stabilises. If pain lingers well after your flight, that is a sign the underlying tooth issue needs proper evaluation.

When to See a Dentist

If tooth pain during flights or altitude changes keeps happening, do not dismiss it as just "one of those things." It is your tooth signalling a problem that pressure changes are simply exposing. A dental exam and, if needed, an X-ray can usually pinpoint the exact tooth and cause.

Treatment depends entirely on the cause, and costs in Sector 15, Gurugram typically range based on whether it is a simple filling, a crown replacement, or root canal therapy. Your dentist can give you a clearer estimate once the exact issue is identified.
